From rem-conf-request@es.net Tue Jun 1 21:47:37 1993 Date: Wed, 2 Jun 93 0:36:46 EDT From: Jim Martin To: rem-conf@es.net Subject: Space Shuttle audio on the MBone Status: RO Content-Length: 11846 X-Lines: 264 Gentlepeople, I happen to have access to the NASA Select audio channel during the upcoming STS-57 mission. This broadcast includes almost all of the audio communication between Mission Control and the Endevour as well as periodic status and informational messages. I've mentioned a few times on MBone Audio that I would be multicasting the broadcast within Rutgers and asked if others were interested. A number of people were, so starting with the launch during the evening (EDT) of June 3rd (Thursday) I will be transmitting the Shuttle audio Internet-wide with a TTL of 127. This broadcast will continue through the landing 6 or 7 days later. Be aware that there are often times of silence during these broadcasts, so be patient! Attached below are some mission highlights and the mission schedule. If anyone has a real problem with this, or if you have any suggestions, let me know. Jim ---- Included Text Follows: ---- FIRST SPACEHAB FLIGHT HIGHLIGHTS STS-57 SHUTTLE MISSION The beginning of a new era in the commercial development of space and the retrieval of a European satellite highlight NASA's Shuttle Mission STS-57. The mission, scheduled for early June 1993, also will see Space Shuttle Endeavour and her six-person crew use experiments designed by and for students, operate a payload which may improve crystal growth techniques and demonstrate possbile on-orbit refueling techniques. A rendezvous with the European Space Agency's European Carrier (EURECA) satellite is scheduled to take place on the fourth day of the mission. The Shuttle's robot arm will be used to grapple the satellite. It then will be lowered into Endeavour's cargo bay and stowed so it can be returned to Earth. The EURECA satellite has been on-orbit collecting data since its deployment during Shuttle Mission STS-46 in July 1992. On STS-57, NASA will be leasing a privately-developed mid-deck augmentation module known as SPACEHAB. The primary objective is to support the agency's commercial development of space program by providing additional access to crew-tended, mid-deck locker or experiment rack space. This access is necessary to test, demonstrate or evaluate techniques or processes in microgravity. NASA's secondary objective is to foster the development of space infrastructure which can be marketed by private firms to support commercial microgravity research payloads. In this instance, SPACEHAB, Inc., has the capability of leasing SPACEHAB facility space to other commercial customers on upcoming flights of the module. The experiments flying inside this first SPACEHAB include investigations ranging from drug improvement, feeding plants, cell splitting, the first soldering experiment in space by American astronauts and high-temperature melting of metals. Included are 13 commercial development of space experiments in material processing and biotechnology, one NASA biotechnology experiment and five other NASA investigations related to human factors and the Endeavor's environment and a space station environmental control system test. Three other payloads, the Get Away Special (GAS), the Consortium for Materials Development in Space Complex Autonomous Payload-IV (CONCAP-IV) and the Superfluid On-Orbit Transfer (SHOOT) payload will be carried in Endeavour's cargo bay. The GAS system, which has flown many times on the Space Shuttle, allows indiviudals and organizations around the world access to space for scientific research. During the STS-57 mission, 10 GAS payloads from the United States, Canada, Japan and Europe will perform a variety of microgravity experiments. The CONCAP-IV payload is the fourth area of investigation in a series of payloads. It will investigate the growth of nonlinear organic crystals by a novel method of physical vapor transport in the weightlessness of the space environment. Nonlinear optical materials are the key to many optical applications now and in the future with optical computing being a prime example. The SHOOT payload is designed to develop and demonstrate the technology required to re-supply liquid helium containers in space. Because so little experience exists with cryogen management in microgravity, SHOOT is designed to gather data about how the liquid feeds to pumps, the behavior of the liquid/vapor discriminators and the slosh and cool down of the liquid. Middeck Experiments Two experiments which previously have flown aboard the Shuttle will be carried in Endeavour's middeck area. The Fluid Acquisition and Resupply Experiment (FARE), which last flew on Shuttle Mission STS-53 in November 1992, will continue to investigate the fill, refill and expulsion characteristics of simulated propellant tanks. It also will study the behavior of liquid motion in microgravity. The Air Force Maui Optical System (AMOS) is an electro-optical facility located on the Hawaiian Island of Maui. The primary objectives of AMOS are to use the orbiter during flights over Maui to obtain imagery and/or signature data from the ground-based sensors. Spacewalk on STS-57 STS-57 crew members David Low and Jeff Wisoff will perform a 4-hour extravehicular activity (EVA) on the fifth day of the flight as a continuation of a series of spacewalks NASA plans to conduct to prepare for construction of the space station. The spacewalk tests, the first of which was performed on STS-54 in January 1993, are designed to refine training methods for spacewalks, expand the EVA experience levels of astronauts, flight controllers and instructors, and aid in better understanding the differences between true weightlessness and the ground simulations used in training. In addition, since the Shuttle's remote manipulator system mechanical arm will be aboard Endeavour to retrieve EURECA, the STS-57 spacewalk will assist in refining several procedures being developed to service the Hubble Space Telescope on mission STS-61 in December. Education NASA's on-going educational efforts will be represented by two payloads. The Get-Away Special (GAS) #324 - CAN DO experiment is designed to take 1,000 photos of the Earth allowing students to make observations and document global change by comparing the CAN DO photos with matched Skylab photos. The primary payload of CAN DO, known as GEOCAM, contains four Nikon 35mm cameras equipped with 250 exposure film backs. The GEOCAM system will match closely the larger Skylab film format in both coverage and quality allowing direct examination and comparison of the changes that have occurred to the planet in the last 20 years. The canister also contains 350 small, passive, student experiments. STS-57 crew members will take on the role of teacher as they educate students from around the world about their mission objectives and what it is like to live and work in space by using the Shuttle Amateur Radio Experiment (SAREX) experiment. Brian Duffy and Janet Voss will operate SAREX. Operating times for school contacts are planned into the crew's activities. Mission Summary Leading the six-person STS-57 crew will be Mission Commander Ronald Grabe who will be making his fourth space flight. Pilot for the mission is Brian Duffy, making his second flight. Leading the science team will be Payload Commander David Low who also is designated as Mission Specialist 1 (MS1) and is making his third flight. The three other mission specialists for this flight are Nancy Sherlock (MS2), Jeff Wisoff (MS3) and Janice Voss (MS4), all of whom will be making their first flight. The mission duration for STS-57 is planned for 6 days, 23 hours, 19 minutes. However, the mission may be extended by 1 day immediately after launch if projections calculated at that time for energy and fuel use during the EURECA rendezvous permit. If for some reason STS-57 remains a 7-day flight, the extravehicular activity scheduled for flight day five would be cancelled. The STS- 57 mission will conclude with a landing at Kennedy Space Center's Shuttle Landing Facility. This will be the fourth flight of Space Shuttle Endeavour and the 56th flight of the the Space Shuttle system.

If you intend coming along, please let me know. (The secretariat need an estimate of numbers so they can allocate a suitably-sized room.) IETF Meeting in Amsterdam BOF Session on NETWORKING MULTIMEDIA APPLICATIONS (currently scheduled for Tuesday 13 July, 1930-2200) The ready availability of user-friendly multimedia authoring tools such as Authorware Professional, Asymmetrix Multimedia Toolbook, Macromind Director and many more, has stimulated much interest in multimedia within the user community. Sophisticated interactive multimedia applications are being developed in many disparate subjects and for a wide range of purposes. Users are now beginning to ask us, as network technologists, "how can I make my multimedia application available to others across the network?". In a parallel development, existing client-server network information retrieval tools are being enhanced with multimedia handling features. Gopher+ for instance has been designed with multimedia data firmly in mind. The World Wide Web project is currently defining a new version of its hypertext markup language, to be called HMML - HyperMedia Markup Language - which includes multimedia support. A third strand of activity is the emergence of network technologies capable of carrying audio and video data across the network, initially driven by multimedia conferencing applications. Network technologies such as ATM and protocols such as RTP are potentially capable of handling isochronous multimedia data in an effective way. This BOF session will focus on issues which link these three strands. Particular questions to be addressed are: * What are user requirements in terms of responsiveness, and what demands this places on the network and server system, and how these might be mitigated. * The prospects for making existing interactive multimedia applications available over the network - eg by writing conversion tools from proprietary formats to a suitable open format. * To what extent can existing network information retrieval tools such as Gopher, WWW, WAIS be used for sophisticated multimedia applications? What about the tools emerging from the research community such as AthenaMuse 2 (MIT), Microcosm (U of Southampton), HyperG (U of Graz)? Do we need another tool, or can we build on what we have? * How can such tools be enhanced to take advantage of isochronous data streams? * What relevance do standards such as HyTime and MHEG have? The BOF is intended to test interest in the subject, to define issues that need resoving, and to see whether a WG can be formed to work on those issues.

Metzger" Content-Length: 1495 Status: RO X-Lines: 30 Very often, people in fora like this note that the experiments we are doing with video and audio over the internet are just "experiments" and that the internet isn't really the right platform for doing things like this. My query for the list is, "Why"? Given an appropriate IP:TNG so that everyone in the world can have their home on the internet, and given appropriate additions to the routing protocols to allow things like bandwidth reservation along particular paths, why shouldn't IP:TNG or something like it be "the only communication protocol you'll ever need"? Why shouldn't day-to-day television, radio, telephony, data transmittion and everything else actually go down the same cable via the same protocol? Naturally the routing systems we use now aren't up to this task -- but future routers specifically designed for an internet in which much of the traffic is real time don't really seem that outlandish. Naturally we don't currently have the bandwidth to do all this, but as we all know thats rapidly changing. So, to the people who assert that the internet is not going to be, among other things, the telephone, videophone, and cable TV system of the future, I ask the question "Why shouldn't it be?" Perry Metzger PS I fully realize that a system only capable of transmitting two or five frames a second (like the ones we have now) with random pauses isn't acceptable -- but then again, we are using todays routers and low bandwidth. My question only addresses the future.

Chances are your officemate was videoteleconferencing by turning the computer screen into a version of a videophone. He may also use a camcorder/computer combo to add video footage to presentations. Now the FlexCam from VideoLabs of Minneapolis offers a more elegant solution: a tiny color camera about 1.5 inches in diameter perched on the end of an 18-inch flexible stalk. Twist the FlexCam to point to an an object or a document, or set it directly in front of your monitor so you can communicate eyeball to eyeball without looking away from the screen. The spherical head of the camera contains the lens and light sensor, plus two stereo microphones. These are connected to audio and video processors in the base by an electric cable. The FlexCam works with all popular video teleconferencing and editing packages for IBM-compatible PCs and Macintoshes and sells for $ 595... Luckily the FlexCam isn't chained to a desk -- it also can work as a candid camera when plugged into a VCR. ------ Looks like a nifty gadget from the picture ... Anyone seen this in real life?

It also affords quick alternation between showing your face and something down on the desktop. The on/off switch on the base (which controls both the video and the audio) and the "on" light indicator are good privacy features (although the light indicator is too subtle to be easily seen under normal lighting conditions). Having the microphone packaged with the camera is a big plus for desktop conferencing use. We actually went through two versions of the camera. The first version had poor low light performance in an interior (no window) office with flourescent lighting, although it performed acceptably in a window office. The audio appeared to be somewhere between mike level and line level. VideoLabs said that both problems were addressed in an upgrade, which they sent us. The upgrade had reasonably good video image performance in a window office. The audio level was good for input to a SPARCstation--worked with an attenuator plugged into SPARC audio just as we do with a camcorder audio line level. Field of view was good--wider than a standard camcorder. However, performance in an interior office was still poor. For some reason, the auto-iris was being fooled to close down more than needed. Consequently, the subject appeared very dark, and the video image would not be acceptable without supplemental lighting. It doesn't help that all of our office walls are painted white, tending towards a backlight problem for the camera. When we chatted with VideoLabs again about the low-light problem, they indicated that they had discovered a problem in some of their CCD camera components, so we're waiting to hear what adjustments might be made to address the problem. We're evaluating two other desktop conferencing cameras at the moment, and so far the VideoLabs FlexCam does seem to be the best overall package, although low-light performance and backlighting problems seem to be an issue for all of them.

It addresses QoS specification through flow specification, but does NOT specifiy any mechanisms to achieve this. It relied initially on the cute DQDB variant employted on BBns terrestrial wideband net, and currently (at least to UCL) on an ad hoc IP 'fair share'/resource control mechanis, again unspecified... 2. It includes its own Multicast/Group Control which has at least once undergone revision (in implementation) because of hitting problems that were already known about in IP multicast 3. It has been criticisd elsewhere as overly complex 4. It competes unnecesarily for implementation effort wqith some of the IPng proposals which address many (but not all, yet) of the problems... my view is a) leave IP as the basis of current routing including multicast b) enhance it through IPng work to provide i) more scalable multicast ii) resource control through a seperate resource specification protocol (e.g. rsvp, but ST could be used in part i nthe same way too..) basicaly, i feel ST-II falls between two stools - I - end to end resource control, based on adaptive playout and congestion avoidance, etc II - use of underlying ATM net to do same job... (whose signalling already does (1). if you want to share the net with IP traffic, you HAVE to solve the resource control problem at the IP level. there: you wanted a debate! jon p.s. i have another problem with the current clear, legitimate overlap between big-internet and rem-conf, but that's another cross-posting...which i'm not going to make From rem-conf-request@es.net Wed Jun 16 06:45:06 1993 Date: Wed, 16 Jun 93 9:20:42 EDT From: Chip Elliott To: rem-conf@osi-west.es.net Subject: ST-II Implementations Status: RO Content-Length: 469 X-Lines: 16 I've been (slowly) writing a paper on the existing ST-II implementations. At present count, there are 13 different implementations; some are based on the two public domain versions, some are not. Interest is particularly lively in Europe, primarily due to the BERKOM project. Thus absence of ARPA funding does not mean absence of interest in ST-II. In fact, ST-II seems to be enjoying something of a boom time right now, mainly for multimedia data streams. -- Chip From rem-conf-request@es.net Thu Jun 17 11:05:43 1993 Received: from research.att.com by osi-west.es.net with SMTP (PP) id <05140-0@osi-west.es.net>; Thu, 17 Jun 1993 07:47:41 +0000 Received: by inet; Thu Jun 17 10:46 EDT 1993 Date: Thu, 17 Jun 93 10:46:34 EDT From: hgs@research.att.com (Henning G.

Sometime later this week I will be installing a Sparc 1+ on a subnet which is not connected to other local multicast infrastructure but with sufficient IP bandwidth to carry two tunnels out into the NSFnet. Its name will be zworykin-66 (look it up in your technology dictionary). If the US top level distribution points have sufficient BW facing NSFnet to carry an additional tunnel each, we can inject routes and traffic from zworykin with metrics and TTLs comparable to what we expect from europe. Is this feasible from the top level distribution points? How do we prevent backfeeding Europe? What I don't have is good signal generators. zworykin will have rather uninteresting video sources and no reasonable audio sources. I would strongly prefer to have either pre-recorded clips with precisely known packet traces or computational (audio and video) sources. Some comments about local topology: Snipe sits on the ethernet DMZ to ENSS132, zworykin will be in our Cray machine room, and have connectivity via the FDDI interface on ENSS132. zworykin could sustain 2*400Kb/S for 24*7 hours without any difficulty. I will be happy to run the test generators on what ever schedule best serves the community, as long as it can be implemented with cron. I have a tool that I will send out later today that directly measures availible CPU cycles on a unix router. Although theory suggests that Snipe should be out of steam, I have measured it and it is not.

Jim ---- Included Text Follows: ---- FIRST SPACEHAB FLIGHT HIGHLIGHTS STS-57 SHUTTLE MISSION The beginning of a new era in the commercial development of space and the retrieval of a European satellite highlight NASA's Shuttle Mission STS-57. The mission, scheduled for early June 1993, also will see Space Shuttle Endeavour and her six-person crew use experiments designed by and for students, operate a payload which may improve crystal growth techniques and demonstrate possbile on-orbit refueling techniques. A rendezvous with the European Space Agency's European Carrier (EURECA) satellite is scheduled to take place on the fourth day of the mission. The Shuttle's robot arm will be used to grapple the satellite. It then will be lowered into Endeavour's cargo bay and stowed so it can be returned to Earth. The EURECA satellite has been on-orbit collecting data since its deployment during Shuttle Mission STS-46 in July 1992. On STS-57, NASA will be leasing a privately-developed mid-deck augmentation module known as SPACEHAB. The primary objective is to support the agency's commercial development of space program by providing additional access to crew-tended, mid-deck locker or experiment rack space. This access is necessary to test, demonstrate or evaluate techniques or processes in microgravity. NASA's secondary objective is to foster the development of space infrastructure which can be marketed by private firms to support commercial microgravity research payloads. In this instance, SPACEHAB, Inc., has the capability of leasing SPACEHAB facility space to other commercial customers on upcoming flights of the module. The experiments flying inside this first SPACEHAB include investigations ranging from drug improvement, feeding plants, cell splitting, the first soldering experiment in space by American astronauts and high-temperature melting of metals. Included are 13 commercial development of space experiments in material processing and biotechnology, one NASA biotechnology experiment and five other NASA investigations related to human factors and the Endeavor's environment and a space station environmental control system test. Three other payloads, the Get Away Special (GAS), the Consortium for Materials Development in Space Complex Autonomous Payload-IV (CONCAP-IV) and the Superfluid On-Orbit Transfer (SHOOT) payload will be carried in Endeavour's cargo bay. The GAS system, which has flown many times on the Space Shuttle, allows indiviudals and organizations around the world access to space for scientific research. During the STS-57 mission, 10 GAS payloads from the United States, Canada, Japan and Europe will perform a variety of microgravity experiments. The CONCAP-IV payload is the fourth area of investigation in a series of payloads. It will investigate the growth of nonlinear organic crystals by a novel method of physical vapor transport in the weightlessness of the space environment. Nonlinear optical materials are the key to many optical applications now and in the future with optical computing being a prime example. The SHOOT payload is designed to develop and demonstrate the technology required to re-supply liquid helium containers in space. Because so little experience exists with cryogen management in microgravity, SHOOT is designed to gather data about how the liquid feeds to pumps, the behavior of the liquid/vapor discriminators and the slosh and cool down of the liquid. Middeck Experiments Two experiments which previously have flown aboard the Shuttle will be carried in Endeavour's middeck area. The Fluid Acquisition and Resupply Experiment (FARE), which last flew on Shuttle Mission STS-53 in November 1992, will continue to investigate the fill, refill and expulsion characteristics of simulated propellant tanks. It also will study the behavior of liquid motion in microgravity. The Air Force Maui Optical System (AMOS) is an electro-optical facility located on the Hawaiian Island of Maui. The primary objectives of AMOS are to use the orbiter during flights over Maui to obtain imagery and/or signature data from the ground-based sensors. Spacewalk on STS-57 STS-57 crew members David Low and Jeff Wisoff will perform a 4-hour extravehicular activity (EVA) on the fifth day of the flight as a continuation of a series of spacewalks NASA plans to conduct to prepare for construction of the space station. The spacewalk tests, the first of which was performed on STS-54 in January 1993, are designed to refine training methods for spacewalks, expand the EVA experience levels of astronauts, flight controllers and instructors, and aid in better understanding the differences between true weightlessness and the ground simulations used in training. In addition, since the Shuttle's remote manipulator system mechanical arm will be aboard Endeavour to retrieve EURECA, the STS-57 spacewalk will assist in refining several procedures being developed to service the Hubble Space Telescope on mission STS-61 in December. Education NASA's on-going educational efforts will be represented by two payloads. The Get-Away Special (GAS) #324 - CAN DO experiment is designed to take 1,000 photos of the Earth allowing students to make observations and document global change by comparing the CAN DO photos with matched Skylab photos. The primary payload of CAN DO, known as GEOCAM, contains four Nikon 35mm cameras equipped with 250 exposure film backs. The GEOCAM system will match closely the larger Skylab film format in both coverage and quality allowing direct examination and comparison of the changes that have occurred to the planet in the last 20 years. The canister also contains 350 small, passive, student experiments. STS-57 crew members will take on the role of teacher as they educate students from around the world about their mission objectives and what it is like to live and work in space by using the Shuttle Amateur Radio Experiment (SAREX) experiment. Brian Duffy and Janet Voss will operate SAREX. Operating times for school contacts are planned into the crew's activities. Mission Summary Leading the six-person STS-57 crew will be Mission Commander Ronald Grabe who will be making his fourth space flight. Pilot for the mission is Brian Duffy, making his second flight. Leading the science team will be Payload Commander David Low who also is designated as Mission Specialist 1 (MS1) and is making his third flight. The three other mission specialists for this flight are Nancy Sherlock (MS2), Jeff Wisoff (MS3) and Janice Voss (MS4), all of whom will be making their first flight. The mission duration for STS-57 is planned for 6 days, 23 hours, 19 minutes. However, the mission may be extended by 1 day immediately after launch if projections calculated at that time for energy and fuel use during the EURECA rendezvous permit. If for some reason STS-57 remains a 7-day flight, the extravehicular activity scheduled for flight day five would be cancelled. The STS- 57 mission will conclude with a landing at Kennedy Space Center's Shuttle Landing Facility. This will be the fourth flight of Space Shuttle Endeavour and the 56th flight of the the Space Shuttle system.

However, it may be extended by 1 day immediately after launch if projections calculated at that time for energy and fuel use during the EURECA rendezvous permit. If STS-57 remains a 6-day (MET) flight, the extravehicular activity scheduled for flight day five would be cancelled. Activities planned for the first four flight days would be unchanged. Flight control system checkout, reaction control system hot-fire and Spacehab deactivation would take place on flight day seven. Entry and landing would be on flight day eight. The following is a schedule for the extended, 7-day, 23-hour (MET) mission: Flight Day One Flight Day Six Ascent Spacehab operations OMS-2 (251 n.m. x 169 n.m.) FARE operations Spacehab activation Spacehab operations NC-1 burn (251 n.m. x 174 n.m.) Flight Day Two Flight Day Seven Remote manipulator system checkout Spacehab operations SHOOT operations FARE operations Spacehab operations NC-2 burn (251 n.m. x 178 n.m.) Flight Day Three Flight Day Eight SHOOT operations Spacehab operations Spacehab operations Flight control systems checkout NC-3 burn (251 n.m. x 184 n.m.) Reaction control system hot-fire Spacehab deactivation Flight Day Four Cabin stow EURECA retrieval NSR burn (251 n.m. x 248 n.m.) Flight Day Nine NH-4 burn (257 n.m. x 250 n.m.) Spacehab deactivation completed TI-burn (259 n.m. x 256 n.m.)

This talk should be of great interest to the rem-conf/mbone community, as he will be talking about some of the design philosophy behind tools like vat and wb. ("wb" is LBL's soon-to-be-released shared whiteboard program.) The seminar will be transmitted on the MBone, using PCM audio at a TTL of 191, and nv video at a TTL of 127. The wb session will also be transmitted, at a TTL of 191, for the sake of those folks who are beta-testing wb for Van. Please do *not* ask for a copy of wb if you don't already have one -- we will point the TV camera at the wb display, so you will be able to see it in action over the video session. Individual sessions for all three media are being advertised in sd. For the sake of those without sd, the session parameters are as follows: PARC Forum Audio 224.2.248.152, ttl 191, port 53826, id 12617 PARC Forum Video 224.2.248.152, ttl 127, port 49991 PARC Forum Whiteboard 224.2.248.152, ttl 191, port 62517 I request that the Radio Free Vat DJs refrain from transmitting RFV from 3 pm to 6 pm, PDT, on Thursday. Thanks. Here is the title and abstract for Van's talk, as well as driving directions to the PARC Auditorium for any of you who are in the SF Bay Area; if you are in the area and are interested in hearing the talk, I highly recommend that you attend in person, rather than relying on the "best efforts" of the MBone. -------------- LIGHTWEIGHT SESSIONS -- A NEW MODEL FOR MULTIMEDIA NETWORKING Van Jacobson Lawrence Berkeley Laboratory Although packet audio and video have been a well-funded research topic for more than a decade, the user community has been tiny until quite recently. The past year has seen an explosive growth in the use of the Internet for real-time audio and video conferencing and we have reached a point where every day hundreds of people all over the world use conferencing tools developed at LBL and PARC to work together over the "MBone" -- a globe-spanning IP multicast backbone built on top of the Internet. There are many reasons for this recent growth but perhaps the major one is the evolution of a new protocol and application structure, based on the IP multicast communication model, that we call "Lightweight Sessions". This talk will briefly describe the Lightweight Sessions model and some conferencing tools based on it. Then, after indulging in some wild speculation as to why this model succeeded when earlier approaches based on connection-oriented networking and peer-to-peer communication protocols failed, I will try to convince you that Lightweight Sessions are the wave of the future and "the one true way". -------------- Refreshments will be served at 3:45 P.M. The PARC Auditorium is located at 3333 Coyote Hill Rd. in Palo Alto. We are in the Stanford Research Park, between Page Mill Road (west of Foothill Expressway) and Hillview Avenue. The easiest way here is to get onto Page Mill Road, then turn onto Coyote Hill Road. As you drive up Coyote Hill past the horse pastures, PARC is the building on the left after you crest the hill. Park in the large lot, and enter the auditorium at the upper level of the building. (The auditorium entrance is located down the stairs and to the left of the main doors.)

(I also thought this sounded rather interesting!) The "full-color, full-motion" part is true (most of the time) but the "through Internet data communication network" is over-selling my work. My group has indeed experimented on the internet with an audio/video transport protocol we've developed, however, our work really addresses campus- area networks. Research in multimedia networking at UNC has primarily involved OS & transport services for high-bandwidth, live, digital audio and video. The particular piece of the digital A/V puzzle that we are working on is how conferencing solutions can be obtained using readily available commodity audio and video technology for workstations, and todays' networks based on asynchronous communications. To date, we have demonstrated empirically that it is possible to support most user requirements for (point-to-point) conferences across small (e.g., campus area) packet-switched networks without using special network services, even in the presence of congestion. Part of the goal here was to establish a baseline for measuring the benefits and costs of more specialized solutions. Our arguably parochial network environment was chosen because we expect that networks consisting of a heterogeneous mix of conventional LANs, bridges, routers, and ATM switches will be widely used during the evolution of networks towards ATM. Our work attempts to provide a solution that is particularly applicable if conventional LANs are widely used in the "last mile" to the desktop. As far as the aforementioned demo goes, it's not clear what we'll actually demonstrate (I was only asked to do this yesterday!) but it most certainly will not use any significant portion of the internet.

There are also changes in the mrouted, mrinfo and map-mbone programs to report on down or disabled tunnels and interfaces, and `stub' networks. With the new mrouted and mrinfo, the version number reported is "2.0". These changes were provided by Van Jacobson. The release now includes all necessary files to add IP Multicast support to the following SunOS version and architecture combinations: SunOS 4.1.1: sun3, sun4, sun4c SunOS 4.1.2: sun4c SunOS 4.1.3: sun4c, sun4m The changes to ip_mroute.c and to the mrouted, mrinfo, and map-mbone programs should port directly to other platforms on which IP Multicast is supported. The new release can be fetched from: gregorio.stanford.edu: vmtp-ip/ipmulti-sunos41x.tar.Z or parcftp.xerox.com: pub/net-research/ipmulti-sunos41x.tar.Z It is strongly recommended that all machines running mrouted and attached to the MBone be upgraded to this latest release as soon as possible, in order to improve the robustness and manageability of the MBone. Please report any problems or bugs to mbone@isi.edu. Steve Deering P.S. This release does *not* include a number of significant improvements that are currently under development -- this time we decided not to release major new features so close to the date of an IETF. However, good progress is being made on some important new capabilities. Just today, we successfully tested code that limits the bandwidth allocated to multicast traffic over a tunnel or physical link, with prioritized packet dropping when the demand exceeds the rate limit (e.g., video packets get dropped before audio packets). We have also begun implementing multicast tree pruning in mrouted (at last!), and have designed changes to mrouted to improve the choice of delivery paths (in particular, to prefer higher-bandwidth delivery paths, rather than just minimum-hop paths). We are targetting the end of the summer for release of these new features.

Hi, I am very interested in ST-II. I would appreciate if you could send information about where and how (ftp anonymous, e.t.c) can I find the two public domain versions of ST-II implementations. Futhermore, any information about the 13 different implementations will be very grateful to me.

If you picked up a copy of ip_mroute.c from ftp.ee.lbl.gov earlier this month (anytime since May 28), then you have the same file as the one in the new release. I don't know about any instructions that might have accompanied Van's ip_mroute.c. You should still fetch the new release to get the latest versions of mrouted/mrinfo/map-mbone. They are more recent than any previous versions you may have obtained.

I strongly recommend pre-arranging signal quality monitoring out in the Mbone. This can be used to "ride" the video BW in real time, such that you don't stomp on yourself when illness strikes the mbone. During part of the GCfHPC broadcast we were getting half dozen ICMP's per packet out, so I cut the video rate in half to preserve the audio. I used my own "nvqual" to do the monitering, but it has some problems.... The monitors should be pre-arranged, because otherwise someone will vote the BW down to fit through the weakest link instead of raising the local tunnel threshold. Putting them near the intercontinental distribution points would make sense, but they can't consume too much bandwidth by them selves. The integrated transmission/audience monitoring functions in vat and nv are somewhat problematic. Both would benefit from a "broadcast" mode, in which the transmitter runs as one unix process while the "audience monitor" runs as another (niced as well). When you have several hundred viewers, cold starting or redrawing vat will take painfully long. Other random items: Is there another "MBONE audio" meeting planned? Historicly, we have always received mbone connection requests on the eve of major events. I'd like to suggest that we should widely announce a cut-off date for new connections. How about July 2nd? About backup tunnels (from Casner): >You raise a good point. As I think about it further, even a simple >triangle backup can cause trouble: > > 1 > A --------- B > \ / > \ / > 3 \ /1 > \ / > C > >If AB and BC are the primary tunnels at metric 1, and AC is a backup >tunnel at metric 3, then while everything is up, this collection >represents a load of 1 tunnel to A. But if the BC link goes down, >then A will have to forward traffic over both AB and AC, raising the >load on A to 2. If A already has a full load of other tunnels, this >could cause overload. I suggest solutions for three cases: In the case where "A" is a top level node, solve the problem by quality monitoring at C and drop the broadcast bandwidth when B-C fails. If we use Casner's map, this means something like monitoring at Cornell, JVNC and SESQUInet, each with backup tunnels to the more distant MAE-east level node. (In this case A and B are really a little cloud). If C is part of the "mbone core" it is quite likely that C will receive the signal "backfeed" from further down in the (normal) tree. Since the ratio of active to inactive tunnels drops as you get further down the path, this "backfeeding" is less likely to be a problem. Finally in the case where B is the root of some otherwise singly connected tree (say within one regional), I'd suggest a threshold on the A-C tunnel such that it doesn't pass video. This has the advantage that it damps "counting to infinity" and routing churn.

Last December or so, we had planned on compiling and maintaining a catalog of teleconferencing products. At that time, Chris Adie announced his Survey of Distributed Multimedia Research, Standards and Products. The Products section of his survey covered all of the current tools, and we decided it would not be useful to just duplicate his efforts. What we did decide was to use the products section of his survey as the basis of the catalog in the future, waiting a few months and then checking the currnet status of the listed products and incorporating any new ones. I am just starting to do that, hopefully putting out a newer catalog soon. In the meantime, Chris' survey is available from our ftp server, ftp.concert.net as doc/mmsurvey.ps or doc/mmsurvey.txt.

I'd like more on this .... What do you recommend othere to use ? What were the problems ? Any fixes in hand ? % You raise a good point. As I think about it further, even a simple % triangle backup can cause trouble: % 1 % A ------ B % \ / % 3 \ /1 % \ / % C % % If AB and BC are the primary tunnels at metric 1, and AC is a backup % tunnel at metric 3, then while everything is up, this collection % represents a load of 1 tunnel to A.

In my original (private -- you probably didn't see it) message to Steve, the question I raised was "how many backup channels can a router have ?". Is it a fixed number, or, more likely, some % of the active channels ? My feeling is that we should design backups into the network. If the VJ FO count for a node is "6-7", should we have up to 6 normally active tunnels, and a maximum tunnel count of 7 (or could we manage 8) ? PS: I've just set up a sun3 as an mrouted (I'm thinking of making it a bit like Xkernel) and have no VJ FO # for it. Can I measure it using tcpdump ? Look at the timestamps of the incoming packet and the outgoing packets ? With ip tunnel arriving from external to local1 (ELC) which relays to the LAN (using true multicast) and IP tunnels to clients 1-3. local2 (3/140) receives the LAN multicast and sends it on to clients 4-6. I see something like: 0.000000 external -> local1 0.000382 local1 -> LAN multicast 0.000626 local1 -> client1 0.000869 local1 -> client2 0.001110 local1 -> client3 0.002100 local2 -> client4 0.003570 local2 -> clinet5 0.005035 local2 -> client6 i.e. an ELC can send out packets every 240us, and a sun3/60 every 1270us (all figures +/- 20% or so !!) These figures appears somewhat lower than Van's -- what have I missed ? I assume an ELC is an "SS2" (in fact somewhat less powerful ?), which Van has down as 900us. I would expect the interval between the incoming packet's arrival time and the first outgoing packet might be greater than the interval between subsequent outgoing packets (was this taken into account ?) I see intervals like: ELC: 360, 240, 240, 240 3/60: 1800, 1200, 1200, 1200 So, with a lot of rounding, it's about half a unit to receive the packet, and one unit to xmit each packet. The figure for "1 ms/pkt" was 5 channels, so if an ELC manages about 4 pkts/ms, that makes it about 20 channels ! This would mean that none of the existing "bootenecks" are CPU limited. This shows that a 3/140 can manage 3.5 tunnels ... What have I missed / misinterpreted ?

All products support 2-wire interface for phone lines and 4-wire interface for traditional video codecs. They have built-in power amps for speakers and have connectors for multiple MICs. There is also automaic ambient noise level detection and audio level control. Most of all, they all use DSP-based adaptive echo cancellation to allow full-duplex conversation. Main differences among products come from the degree of cancellation (e.g., echo return loss enforcement (ERLE) in dB, the higher the better), the power amps output level, maximum number of MICs supported, and auxiliary amps for VCR, tape recorder. Here is a list of the products, feature highlights, quoted price, and contact phone numbers: -- Shure ST4300 adaptive acoustic echo canceler: ERLE > 20 dB (with nonlinear processing disabled) adaptive line echo canceler: ERLE > 30 dB (with nonlinear processing disabled) 4-wire audio bandwidth: 300Hz-4 KHz or 50Hz-7KHz selectable price: $3995 -- Coherent Voicecrafter 2000 acoustic echo return loss (AERL) 0dB minimum acoustic echo return loss 65dB minimum, center clipper enabled Enforcement (AERLE) with input level of -10dBm and 6dB ERL (I don't know what these conditions mean yet, please call Coherent for any questions) audio bandwidth: 200Hz-3400Hz or 200Hz-7100Hz selectable price: $6400-$10,000 depending on configuration -- Coherent Voicecrafter 2800 price: $6805-$7995 depending on configuration -- Coherent Voicecrafter 3000 soon to be available on market price: $3995 Fengmin -- Fengmin Gong E-mail: gong@concert.net Network Research Engineer Phone: 919 248-9214 MCNC Center for Communications FAX: 919 248-1405 From rem-conf-request@es.net Mon Jun 28 12:56:29 1993 Received: from mothra.nts.uci.edu by osi-west.es.net with SMTP (PP) id <08184-0@osi-west.es.net>; Mon, 28 Jun 1993 09:41:08 +0000 Received: by mothra.nts.uci.edu id AA11546 (5.65c/IDA-1.4.4 for rem-conf@es.net); Mon, 28 Jun 1993 09:41:04 -0700 Received: from nowayout (nowayout.nts.uci.edu) by mothra.nts.uci.edu with SMTP id AA11537 (5.65c/IDA-1.4.4 for rem-conf@es.net); Mon, 28 Jun 1993 09:41:02 -0700 Message-Id: <199306281641.AA11537@mothra.nts.uci.edu> X-Sender: mtan@mothra.nts.uci.edu Date: Mon, 28 Jun 1993 09:37:20 -0700 To: rem-conf@es.net From: MTan@uci.edu (Mary Tan) Subject: Apology X-Mailer: Content-Length: 78 X-Lines: 5 Status: O I apologize for accidentally forwarding unrelevant mail messages.

With a few improvements, the same basic format as the 1993 conference will be used. The general idea is to build on the success of the first conference by limiting the number of participants, specialization of topics, presenting new problems and problem areas, encouraging the exchange of ideas and generally advancing the state of the art. The conference will be divided into segments with each segment devoted to a specific topic. This will allow for little conflict between segments. All papers will be screened rigorously to ensure the quality of presentations. The number of participants will be limited in order to encourage interaction during and after the formal presentations. In response to suggestions made by last year's participants, we are including both social and cultural activities in the 1994 agenda. Lead Speakers for the conference include: 1. Luigi Fratta, "Deflection Routing Network Architecture" 2. Michel Minoux, "Multicommodity Network Flows and Their Application in Telecommunication Networks" 3.

Every bit probably costs more than its worth and it adds up. (2) Vendors probably compare these boxes with the overall cost of the conventional video conferencing systems, i.e., using video codecs for circuit switched networks, using leased lines from telco, etc. At least that seems to be what they made these boxes for and the price does not loook that ridiculous any more. (3) And you are right about the market factor. I asked one rep at the show about an all-digital and cheaper solution, he said it's up to the packet video people to create the demand. I have heard that there are chip set available for echo control and I am looking into putting my own solution together.

Hmmm, Since Solaris 2.2 is just out I'm wondering if anyone has done full testing on it. The documentation says that most applications compiled under SunOS 4.1.3 will run under Solaris 2.2 (this was NOT true under Solaris 2.1). True this won't help the lack of a VideoPix driver. If anyone has tried 4.1.3 compiled applications under the just released Solaris 2.2 please let me know the results.

The statically linked SunOS 4.x "vat" binary that Van distributes will not run in Solaris 2.1 or 2.2. SunOS 4.x binaries will run in Solaris 2.1 and 2.2, but only if they are dynamically linked. But Van has built a dynamically linked version of "vat" that we have been running under Solaris 2.2, the most recent release of Solaris 2. If he includes a dynamically linked version in his future distributions of "vat", they should run in Solaris 2.2 and subsequent releases. For those of you who can't wait, we have put together a binary re-distribution that includes binaries for "vat", "sd" and "nv" which run in Solaris 2.2. These binaries will also run in Solaris 2.1, however, you will need to install a kernel patch. This distribution is available via anonymous FTP from "playground.sun.com" in "pub/solaris2/vat-dist.tar.Z". Details of how to install and run the programs are in a README file contained in the distribution.

Smaller organizations do not have the resources nor the infrastructure to use this new technology. Small business will face a serious disadvantage in the near future as larger corporations develop efficient methods of working through teleconferencing and groupware. It is virtually impossible for a small business to acess the ISDN lines and other equipment required for this service. To give small business a competitive edge, a communication infrastructure can be built to allow small organizations to communicate rapidly and with nearly the ease of face to face meetings. The Universities of California and New Mexico with participation from Lawrence Livermore National Laboratory and other suppliers, are submitting a proposal to the Advanced Research Projects Agency (ARPA) under the Technology Reinvestment Project (TRP) to fund a project to provide small, defense-expenditure dependent business with access to a national community of research scientists and engineers via video teleconferencing and groupware. These organizations would have available, through their ethernet capable personal computers or workstations, videoconferencing, collaborative work tools, databases, multimedia mail, and bulletin boards. Databases with the participants addresses and phone numbers, areas of expertise and background of participants will be available. We would provide training and support for the use of the equipment. If your are interested in participating in this project, please let me know as soon as possible, preferably by July 2, 1993 to Dr. Meera Blattner, Lawrence Livermore National Laboratory, L-540, P.O. Box 808, Livermore, CA, 94551, or contact me by e-mail (blattner@llnl.gov), or call me at (510) 422-3503. We will fax you the necessary forms and other information required.

However, Solaris 2.x binary versions of a VideoPix device driver, the VideoPix interface library (libvfc.a), the video frame capture tool (vfctool), and the newly created VideoPix XIL pipeline library (xilSUNWvfc.so) are available without support. This software was "ported" from SunOS 4.1.3 to Solaris 2.0 and been used within Sun Engineering as part of other development activities. No problems have been reported with this software, although it has undergone no formal testing. Since proper & formal testing has not been performed, these binaries are considered to be less than Alpha-level.

Herman Towles Sun Microsystems p.s. Some VideoPix install instructions are attached. Installing the VideoPix device driver: 1) login as "root" 2) add the following line to /etc/devlink.tab (NOTE: This line must have *no* spaces) type=ddi_pseudo;name=vfc \M0 3) cp vfc /kernel/drv 4) add_drv -m '* 0666 root bin' vfc 5) ls -l /dev/vfc0 6) boot -r System boots will automatically install the driver if the device is installed on the SBus and found by system probe & selftest.

It turns out that if you plug the FlexCam into a video monitor, the video image shows up well-lit, even in an interior office. We'll tune the software on our board a bit, but I wanted to correct a potentially misleading report on the FlexCam.

SUNSOFT ANNOUNCES NEW SOLARIS 2 CUSTOMER INITIATIVES Speed End-User Transition And Increase Application Base MOUNTAIN VIEW, June 30, 1993 -- SunSoft, Inc. today announced five broad initiatives to enable customers worldwide to further accelerate their move to the powerful Solaris(r) 2 software environment. These new initiatives, which build on SunSoft's current industry momentum, are designed to further increase the presence of Solaris 2 in the enterprise-wide computing arena. Targeted at Global 1000 companies, the programs will enable in-house developers to create applications for Solaris 2 rapidly and cost-effectively and give end users access to a larger number of software packages. SunSoft has already shipped a record 250,000 Solaris 2 licenses in the past six months. More than 650 applications are shipping for the Solaris 2 SPARC(r) environment including products from Autodesk, Lotus, Oracle and Sybase, and more than 1,800 are in the process of migrating to Solaris 2. In the x86 arena, more than 500 applications are expected to ship for Solaris 2 by the end of the year and SunSoft has tripled the number of x86 platforms and peripherals supported by Solaris 2 in the last three months. The initiatives include new Solaris 2 product enhancements, a Solaris 2 communication center, an expansion of SunSoft's popular Catalyst software developer program and a Solaris x86 certification program. In addition, the company will offer the Solaris 1.1 software environment as an option to customers of Solaris 2 on the microSPARC(tm) architecture, allowing corporate users to access existing applications today as they migrate to the new Solaris 2 environment. "Solaris momentum continues in the technology, applications and customer areas," said Jim Billmaier, vice president of product marketing at SunSoft. "With today's announcements, we are equipping our Global 1000 customers with everything necessary to assist in the development of new applications and the rapid conversion of existing applications to the powerful Solaris 2 environment." The customer initiatives are: SOLARIS 2 ENHANCEMENTS - Solaris 2 Binary Compatibility Package As the Global 1000 companies make the transition to the powerful Solaris 2 environment, they require tools that will make the migration easy, fast and cost effective. To achieve this, SunSoft will deliver several new software technologies to the marketplace. The company will extend its Solaris 2 Binary Compatibility Package (BCP) software to enable more of the existing third-party and in-house applications to run on the Solaris 2 environment without modification. In addition to dynamically-linked applications, the extended BCP will also run statically-linked applications, enabling users to run most of their Solaris 1 applications unchanged with no loss in performance. The Solaris 2 BCP currently ships within the standard Solaris 2 environment. The extended BCP with statically-linked support will be incorporated into the next release of Solaris 2 in the fall at no extra charge. - Solaris 2 Network Transition Kit In addition, SunSoft will make a Solaris 2 network transition kit available to customers, allowing them to run the industry-standard Solaris 1 NIS network server software on the new Solaris 2 environment. This will enable corporations to maintain their current network configuration and administrative policies while they transition to the more powerful Solaris 2 NIS+ networking software. NIS+ uses a hierarchical naming model for efficient distributed network administration, lowering the cost of ownership. It maintains a database of the numerous resources across a network, allowing users to transparently access and share data. NIS+ is also scalable and runs on a range of networks, from single LANs to enterprise-wide networks with thousands of nodes. The Solaris 2 network transition kit, which includes the NIS software and media, is priced at $125 for a site license. The kit will be available to SunSoft OEMs in 60 days. SOLARIS 1.1 ON microSPARC SunSoft will also make the Solaris 1.1 software environment available as an option to Solaris 2 customers of microSPARC-based systems, such as the SPARCclassic(tm) and SPARCstation(tm) LX from Sun Microsystems Computer Corp. (SMCC). This will allow end users to take advantage of the price/performance of the microSPARC architecture as they migrate to the new Solaris 2 environment. The next-generation Solaris 2 environment offers features -- such as increased performance, symmetric multiprocessing, multithreading, system administration, security, graphics, multimedia and objects -- to deliver a powerful enterprise-wide computing environment to customers. SunSoft will offer its SPARC(r) OEMs a special Compact Disc (CD) release of Solaris 1.1 for microSPARC immediately. European versions in French, German, Italian and Swedish and Asian versions in Japanese, Korean, Chinese (PRC and Taiwan) will be available to SPARC OEMs in 45 days. System manufacturers worldwide have the option to offer the Solaris 1.1 product to their current and new Solaris 2 customers. For inquiries and pricing, contact individual system manufacturers. SOLARIS 2 COMMUNICATION CENTER SunSoft has established a new Solaris Communication Center to provide just-in-time information on the Solaris 2 transition to system manufacturers. This center will offer a direct electronic mail link between system vendors and SunSoft engineers and a new database repository for daily up-to-date migration information. The database will include product updates, technical articles and access to patches. In addition, it will offer "symptom resolution" -- a program that allows users to type in the words associated with a specific problem and receive an answer immediately. The new center adds to the more than 550 UNIX(r) experts across the world that already support the Solaris environment 7 days a week/ 24 hours a day. For more information, contact 1-800-763-8778 (SOFTSPT) or 510-460-3267. SOLARIS 2 ASSOCIATE PROGRAM The new Associate program extends SunSoft's Catalyst program to specifically address the needs of in-house Solaris 2 software developers. The new program features most of the services already offered to third-party developers and adds specific ones for the in-house developer base. SunSoft will work with system manufacturers and channel partners to begin a pilot program in July. The program will include: Tools - Early access to Solaris products for SPARC and x86 - Early access to developer tools Support - Migration planning support - Access to migration tips database Information - Technical newsletters - Special regional conferences and annual developer conference admission - Regular technical updates For more information, contact 1-800-227-9227 in the United States and local SunSoft offices in Europe and Asia. SOLARIS 2 x86 CERTIFICATION PROGRAM SunSoft offers a new Solaris certification program for testing and certifying systems and peripherals for the Solaris x86 environment. Through the program, SunSoft has already boosted x86 platform and peripheral support more than threefold in the last three months. The Solaris 2 x86 software now supports systems from the leading PC vendors including AST, Compaq, Dell Computer, Gateway 2000, IBM, NEC, NCR and Toshiba. It supports popular video display cards from companies, such as ATI, Compaq and Orchid; network cards from SMC, 3Com and IBM; and the SoundBlaster PRO audio card from Creative Labs. In addition, Solaris x86 has been tested and certified to run with tape subsystems from Archive and Tanberg Panther; pointing devices from Logitech, Microsoft and Mouse Systems; and CD-ROM drives from NEC, Sony and Toshiba. SunSoft plans to support more than 200 peripherals by the end of the year. The certification program offers many features to system and peripheral suppliers including technical support, self-test suites, listings in guides, regular technical updates and marketing promotions. For more information on the program, please contact 1-800-227-9227 in the United States and local SunSoft offices in Europe and Asia.
