He wants to run MBONE on his machine. My question is, does the kernal patches for 4.1.3 apply to 4.1.3_U1?? If not, what other additional changes.upgrades have to be done in order for 4.1.3_U1 to support multicasting?? References/answers/suggestions/pointers are welcome. Thanx.

[I've added int-serv since we're into integrated services issues] Jon: Another way to think of this topic is that the point-to-point links provide a perfect service guarantee: * when the IP layer hands a packet to the p-2-p MAC layer it gets sent immediately while multiaccess LANs provide a different service: * when the IP layer hands a packet to the MAC layer, the packet is transmitted when the MAC transmission rules permit the game is to find a service model that allows us to map between IP's service model and the various MAC models. Mapping to p-2-p is trivial because by the p-2-p rules, anything IP does is, by definition, the p-2-p link's behaviour (unless the link is shared with other protocols). The LAN case is trickier.

This is same the group that brought you the holography lecture last month, and this time we've got all the bugs worked out. We're ready to give you a great show!!! Please email me to let me know if you plan to watch. This is part of a party we're throwing to commemorate the comet Shoemaker-Levy Jupiter impact. We can also offer- a panel of astronomers, dinosaur experts, disaster experts, and historians who will be seeing the comet Shoemaker-Levy impact live (or as live as it gets) at our party. If you want to see their discussion, let me know, I'll arrange it. And of course, we'll take your email questions. I'm sorry its weird time for so many of you, but the improv performance is scheducled as a part of an party/internet extravaganza we're having for comet Shoemaker/Levy impact on Jupiter that night. The comet chunks impact that night from 1PM saturday to 11:55 PM PDT. The party starts at 6PM and goes to 10PM PDT. Hope you will join us!!!

Johnson, Former President of Fulbright Association, The University of Tennessee 11:30 to 11:50 Demonstration of "Multimedia of America (MMOA)" (TM) (tenta- tive): Interconnection of two ShareView units via audio subchannels of a satellite will also be demonstrated by Dr. Mel Muchnik of Governors State University and Mr. Timothy Cook of Nebraska Educational TV. Each of them will uplink analog signals which will be downlinked at the U. of TN to produce two split screens side-by-side, so that how to teach Japanese Kanji brush stroke sequences to students at GSU can be shown on whiteboard of ShareView unit. These demonstrations are toward a one-to-many receive-only ShareView system via inexpensive narrow-band channel of satellite (i.e., our MMOA project), for those students in rural and remote areas where there is no Internet node. Video of instructor, handwriting in color on an elec- tronic whiteboard, image/graphic with annotation, dynamic graphic presentation by real-time execution of an application program/simulation model, etc., can be seen in windows on computer screen at students' sites. Yet these experiences can include high levels of interaction and feedback (via email, fax, etc.) amongst students and instructors. 11:50 to 11:55 General questions 11:55 to 12:00 Closing remarks by Dr. Takeshi Utsumi, President of Global University/USA PARTICIPATION: The computer screen will be uplinked for worldwide broadcast. If you have a satellite downlink facility and our satellite foot-prints cover your area, you can receive our satellite signal. You can also participate with your personal computer and/or workstation which are directly connected to TCP/IP oriented Internet without use of satellite nor dish antenna. Other than participation fee, all participants have to be responsible for the costs of (1) down/uplinking from/to satellites; (2) telephone call to a videoconference center at the U. of TN for Q&A; and (3) sending fax to the center for backstage coordination. ************************************************************************ * Takeshi Utsumi, Ph.D. * * President, Global University in the U.S.A.

If you routinely use the same machine, you can change the .sd.tcl file so that it starts vat in mixer mode pointed at your machine (change the "exec $vat ..." line to something like exec $vat -N "Mixer for " -m /6666/0 -C $sd_sess(name) $packetfmt $confaddr & and run Maven with port 6666. The port stuff is a nuisance, but vat refuses to use the same port for the mixed-in conference and the main conference (I'm not sure why). I use 6666 to be unlikely, and to avoid the default port. You don't need to explicitly connect from Maven when you do this. You can also do more clever stuff with Tcl to automatically extract the target machine from the DISPLAY environment variable. You should have Maven 2.0a16, the latest version. But this version does not work on Power Macintoshes, for unknown reasons. joe P.S. When OpenTransport is released, Macintoshes will be able to receive multicast data directly, without using an intermediary. In the mean time, using MacX and Maven with a Unix host is a solution that works. -- Joe Pallas ATG Integrated Systems "Focused, empowered, and impactful" From rem-conf-request@es.net Thu Jul 07 18:11:59 1994 Received: from philabs.philips.com by osi-west.es.net via ESnet SMTP service id <13035-0@osi-west.es.net>; Thu, 7 Jul 1994 15:11:32 +0000 Received: from mars.Philabs.Philips.Com by philabs.Philips.COM (smail2.5/12-15-87/4.1) id AA20400; Thu, 7 Jul 94 18:11:28 EDT Received: by mars.Philabs.Philips.Com (4.1/SMI-4.1) id AA03501; Thu, 7 Jul 94 18:11:27 EDT Date: Thu, 7 Jul 94 18:11:27 EDT From: jec@philabs.Philips.COM (Jorge E.

With a few changes, the same basic format as the 1994 conference will be used. The general idea is to build on the success of earlier conferences by limiting the number of participants, concentrate on a few topics, present new problems and problem areas, encouraging informal interaction and exchanges of ideas. The objective is to advance the state of the modelling and analysis in telecommunications by stimulating research activity on new and important problems. 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, social and cultural activities will be included in the 1995 agenda. The Program Committee includes: Anant Balakrishnan - MIT Jerome Chifflet - CNET Suk-Gwon Chang - Hanyang U. Imrich Chlamtac - University of Massachusetts at Amherst John Daigle - MITRE Robert Doverspike - Bellcore Bezalel Gavish - Vanderbilt University (Chairman) Andre Girard - INRS-Telecom Richard Harris - Royal Melborn Institute of Technology Konosuke Kawashima - NTT Raj Jain - DEC Jeff Mackie-Mason - U. of Michigan Benjamin Melamed - NEC, USA Michelle Minoux - U. of Paris June Park - U. of Iowa Miguel A. Perez - Katolique U. of Chile Scott Rogers - Toronto U. William W. Sharkey - Bellcore David Simchi-Levi - Columbia University Edward A. Sykes - University of Virginia Yutaka Takahashi - Kyoto University Nicos Van Dijk - U. of Amsterdam Listed below are some of the potential segments: -- Topological Design and Network Configuration Problems -- Design and Analysis of Local Access Networks and Outside Plant Problems -- Low Earth Orbit Satellite communication systems -- Time Dependent Expansion of Telecommunication Systems -- Designing Networks for Reliability and Availability -- Network Design Problems in Gigabit and Terabit Networks -- LAN, WAN Global Network Interconnection -- Quantitative Methods in Network Management -- Pricing and Economic Analysis of Telecommunications -- Impact of Telecommunications on Industrial Organization -- Performance Evaluation of Telecommunication Systems -- Distributed Computing and Distributed Data Bases -- Cellular Systems and PCS Modelling and Configuration The Program Committee is open to any ideas you might have regarding additional topics or format of the conference. The intention is to limit the number of parallel sessions to two. The conference is scheduled over a weekend so as to reduce teaching conflicts for academic participants and to take advantage of weekend hotel airfare rates. This message is sent to a select group of participants which the Program Committee feels will benefit from and will contribute to the conference success. Due to the limited number of participants early registration is recommended. To ensure your participation, please use the following steps: 1. Send to Bezalel Gavish (address below) by August 1, 1994, a paper (preferable), or titles and abstracts for potential presentations to be considered for the conference. Sending more than one abstract is encouraged, enabling the Program Committee to have a wider choice in terms of assigning talks to segments. Use E-mail to expedite the submission of titles and abstracts. 2. Use the form at the end of this message to preregister for the conference. Some institutions require participants to have formal duties in a conference in order to be reimburesed for expensses, let us also know if you would like to have a formal duty during the conference as: Session chair, or discussant. 3. You will be notified by October 15, 1994, which abstract/s have been selected for the conference. December 1, 1994, is the deadline for sending a complete paper. The paper will go through a quick review process and feedback will be sent back by January 1, 1995. A final version of the paper is expected by January 30, 1995. Participants will receive copies of the collection of papers to be presented. All papers submitted to the conference will be considered for publication in the "Telecommunication Systems" Journal. The Program Committee looks forward to receiving your feedback/ideas. Feel free to volunteer any help you can offer. If you have suggestions for Segment Leaders (i.e., individuals who will have a longer time to give an overview/state of the art talk on their segment subject) please E-mail them to me. Also, if there are individuals whose participation you view as important, please send their names and E-mail addresses to the Program Committee Chairman, or forward to them a copy of this message. I look forward to a very successful conference.

Weaver, Robert Simoncic James F. McNabb, Bert J. Dempsey Department of Computer Science University of Virginia Charlottesville, Virginia, USA Content Upper layer protocols can either assist or inhibit the development of multimedia applications. In this tutorial we first examine the characteristics of audio/video bitstreams with regard to their bandwidth, latency, and jitter requirements, and their sensitivity to compression. From these observations we deduce the support services that should be supplied by a modern communications network. Next we look at the network protocols and services which are currently available or soon to be deployed. We will cover: (1) IP multicast and how it is implemented in the MBONE; (2) ST-II, a network layer protocol for resource reservation; (3) RSVP, a recent proposal for achieving resource reservation within the Internet; and (4) the Xpress Transfer Protocol (XTP), a recent proposal that provides unique functionality (transport layer reliable multicast, multicast group management, message priorities, selective retransmission, and orthogonal error, flow, rate, and burst control options) thought to be useful for multimedia data flows. XTP can operate over any network layer (e.g., IP, CLNP) or directly on the datalink layer. We explore the myth that transport layer retransmission is unusable or inappropriate as an error control technique for multimedia streams. We present analytic, simulation, and empirical evidence that shows why and when this technique is useful. Finally, we discuss the influence of high speed ATM networks on multimedia applications and their protocols. Text/Book: Strayer, W.T., Dempsey, B.J., and Weaver, A. C.,"XTP: The Xpress Transfer Protocol,"Addison-Wesley, 1992. Handouts of the tutorial. Both included in the fee of the tutorial.. Instructor Alfred C.

MULTIMEDIA IN OPERATING AND COMMUNICATION SYSTEMS Ralf Steinmetz, Ralf Guido Herrtwich IBM European Networking Center Creative Multimedia Studios Heidelberg, Germany Content Multimedia means audio and video in computing and communications; a multimedia system is characterized by the integrated computer-controlled generation, manipulation, presentation, storage, and communication of independent discrete and continuous media. Key issues of multimedia systems concerning the user demands and the derived implementations with respect to operating and communication systems are presented. The notion of multimedia data, real-time and multimedia applications, details on troughput, compression, operating system mechanisms, and communication system features are introduced. For synchronization some media correlation examples are presented to derive user requirements. Building blocks and key issues are identified. The resource management in local and distributed systems, the notion of resources, types of resources, capacities and the phases of the resource management process are outlined in detail. Examples of local as well as distributed mechanisms and protocols are provided. Operating system mechanisms for scheduling according to the multimedia real-time demands are outlined and compared. Existing operating systems are taken into account. File systems mechanisms for storage and retrieval of multimedia data are described. In the area of multimedia communication systems, the focus lies on the exploitationof existing network capabilities. Results from the operating system environment can be used to "schedule" packet on networks. Media scaling can be used to adapt the data streams to the communication capabilities.

ATM - NETWORKING AND ENGINEERING CONCEPTS FOR INTEGRATED SERVICES Paul J. Kuehn University of Stuttgart, IND Stuttgart, Germany Content The Asynchronous Transfer Mode (ATM) is the basis for the integration of constant and variable bitrate traffics as they appear in the integration of services, such as voice, video, and data. Therefore, ITU-TS has recommended ATM as the transfer mode for the future broadband-ISDN. ATM, however, is also applicable to local area networks, and it seems that it will evolve as the universal transfer mode in our future communication networks. The Tutorial will be structured as follows: Service characteristics and network requirements STM and ATM principles Architecture of ATM networks Wide and local area ATM networks Quality of service and traffic control Modelling and performance of ATM networks Traffic engineering for ATM networks The networking requirements are motivated from the various characteristics of a wide spectrum of services. The architecture of ATM networks, i.e. the physical, ATM and ATM Adaption, layers and their functionalities are introduced formally and technically. A key role plays the Quality of Service (QOS) in integrated services networks which depends on the traffic source characteristics, traffic control (such as usage parameter control UPC, connection admission control CAC and routing) and on the traffic load. The networks performance relies therefore on a proper resource management and capacity engineering. The key modelling issues, performance analysis methods and results are presented to build a common basis for understanding ATM networks. Text/Book: Handel, R, Huber, M.: "Integrated Broadband Networks, Addison-Wesley, 1991. Handouts of the tutorial. Both included in the fee of the tutorial. Instructor Paul J. Kuehn received his Dr.-Ing. and Dr.-Ing. habil. degrees from the University of Stuttgart in the field of performance modelling of computer and communication systems. He joined AT & T Bell Laboratories in 1977 where he was involved in data communication networks. In 1978 and 1982 he was appointed full professor for communications switching at the University of Siegen and Stuttgart, respectively. Since 1985 he and his institute are involved in ATM and high speed network research funded by RACE, ESPRIT and national research programs. Professor Kuehn has been awarded the IEEE Fellow degree; in 1991 he was elected chairman of the International Advisory Council of the International Teletraffic Congress. In 1993 he has been elected as Member of the Academy of Sciences in Heidelberg, Germany.

Comments, corrections, and improvements are welcomed. ============================================================= * READ THE FAQ LIST, available at ----------------- ftp://venera.isi.edu/mbone/faq.txt or http://www.research.att.com/mbone-faq.html The rest of these instructions assume that you have read the FAQ. ----------------------------------------------------------------- * make sure that your network provider can supply a multicast feed Call your network provider/manager. If they don't already get MBONE packets but are willing to try and get them for you, point them to a copy of the FAQ, which explains how they can ask about a feed. * subscribe to the mbone mailing list by sending a message to and asking to be added. If you have any problems while trying to do the install, or if you can't find multicast binaries for your machine, chances are that someone else has had the same question. The first thing to try is to download the archives (ftp://venera.isi.edu/mbone/mbone.mail) and browse/search through the file to see if it's already been mentioned on the list. The second thing to try if you should have problems is to browse through various MBONE resources available via the World Wide Web. http://genome-www.Stanford.EDU/~mosedale/mbone.html contains a meta-directory of many of them. * configure machine(s) for multicasting How much work you need to do to get multicasting going depends in large part on how modern your OS is. Notably, Solaris (2.1+), BSD/386 (1.1+), DEC OSF/1 (2.0+), and IRIX (4.0+) come with kernel support in place. From here on, I will assume that you will be running your multicast applications on the same machine that you use to run mrouted (assuming your LAN needs a tunnel). If the machines you have are all slow, you may want to configure two machines for multicasting and split the duties. As far as kernel multicast support and fixes for various boxes: WARNING - I have not tested all of the platforms listed here and thus cannot personally verify that they all work. Further, some applications may not be available for every platform. SunOS, Ultrix- Available for ftp from ftp://gregorio.stanford.edu/vmtp-ip/ipmulti*. Although it's not so-labelled, the Ultrix patches are said to work with Ultrix 4.3 as well. A newer version (warning: it's still in beta-test!) can be found at ftp://parcftp.xerox.com/pub/net-research/ipmulti-*. To install the gregorio patches, (and maybe the xerox ones also), Ignacio Martinez gives this tip: > Configure kernel and patch kernel code with the sources > included in the distribution (the important thing here is > not just copying the object files *.o and rebuilding, but > generate new *.c & *.h files from the patches as well) Solaris 2 Working kernel support is included in Solaris 2.3. Earlier versions may require a patch. Get this and other stuff from ftp://ftp.uoregon.edu/pub/Solaris2.x/src/MBONE/Solaris2.x. IRIX 4.0.x the mrouted and kernel included with IRIX 4.0.x is badly broken; you must get and install the patches from ftp://sgi.com/sgi/ipmcast. IRIX 5.* newer versions of mrouted, mrinfo and map-mbone can be found at ftp://sgi.com/sgi/ipmcast; this is recommended but not necessary. BSD/386 1.1 From the vat README file: > Not all of the IP Multicast changes made it into BSD/386 v1.1. > In particular, the in_pcb fixes that bring the network code > into conformance with the Host Requirements RFC were left out. > Apply the kernel source patches in > > ftp://ftp.ee.lbl.gov/INPCB-bsd386-v1.1-patch > > if you'd like your kernel to properly demultiplex > multicast packets. If you don't have source, check out ftp://ftp.adelaide.edu.au/pub/av/multicast/bsd386*.tar.Z HP/UX 9.01 ftp://ftp.adelaide.edu.au/pub/av/multicast/ipmulti-hpux.tar.Z contains kernel patches and mrouted. AIX 3.2.5 (RS/6000) ftp://gated.cornell.edu/pub/multicast/aix325-ipmcast.tar.Z ftp://ftp.adelaide.edu.au/pub/av/multicast/aix325-ipmcast.tar.Z DEC OSF/1 (Alpha) v2.0 includes multicast kernel support, but not mrouted. ftp://genome-ftp.Stanford.EDU/pub/mbone/mrouted2-osf.tar.Z has both sources and binaries. v1.3 require kernel patches as well as mrouted; get them at ftp://ftp.adelaide.edu.au/pub/av/multicast/ipmulti-decosf1.tar.Z NetBSD 0.9 ftp://ftp.adelaide.edu.au/pub/av/multicast/netbsd-0.9-mcast.tar.Z * get sd, vat, wb, and the lbl version of ghostscript from the subdirectories of ftp://ftp.ee.lbl.gov/conferencing - install them as per the instructions - note that for some machines (notably Digital boxes), you will also need to ftp and install AudioFile in order to use vat. Details are supplied in the README file for vat. * get nv from ftp://parcftp.xerox.com/pub/net-research - binaries for some machines are available as nvbin-3.2-* - binaries for many newer machines available in the exp subdirecory as nv3.3alpha-*. Note that this is an alpha-test version, however, it's been extremely stable in the couple of months that I've been using it. - install it as per the instructions * with help from net-provider, configure a tunnel using mrouted (if necessary) - Using the information in the man page for mrouted, the FAQ list (which has a specific section about this), and help from your network provider, configure a tunnel to put multicast packets on your LAN. * test sd - within a minute or so (maximum) of starting up sd, you should see at least six sessions, often times a lot more. If not, wait a while and try again (very occasionally, the entire MBONE loses connectivitiy). If this doesn't do it, check out the mailing list archives and www resources mentioned above. If you don't find anything there, send mail to the mbone list. * test vat - on some machines, you may need to start the AudioFile server at this point. - in sd, select the "MBONE audio" session. This will start vat. You should quickly see the names of 20 or more people; there are always this many hanging around. Select the help button for some info about how vat works. - if you have a microphone, turn it on. Use the procedure described in the help window to ask if anyone on the net is hearing you. - test nv - in sd, if there are any conferences going on which advertise video in the nv format, click on them. You should see pictures. - if there are no such conferences, click on "MBONE video." If you have a mike, you can ask the "MBONE audio" session if someone can send you some video for testing. Most of the time, nothing is being broadcast on MBONE video. - test wb - select an sd session that includes whiteboard media. Wb is pretty self-explanatory -- look it over. Participate, if appropriate.

Date: Wed, 13 Jul 94 15:39:55 +0100 From: Gordon Joly At 13:00 GMT/UTC, on July 19, 1994, Victoria Bellotti (EuroPARC) will speak on "Self presentation and self preservation: Managing interpersonal interactions and privacy in ubiquitous computing environments" An announcement will be made in "sd" on the previous day. A remote discussant is sought: please either volunteer yourself, if you feel the topic is within your field, or perhaps suggest a colleague. Abstract. --------- Current developments in information technology are leading to increasing capture and storage of information about people and their activities. This raises serious issues about how individuals and groups can present themselves over computer mediated communication and network systems and also the preservation of privacy. In this talk I shall examine why these issues are particularly important in the introduction of ubiquitous computing technology into the working environment. Certain problems with privacy are closely related to the ways in which the technology attenuates natural mechanisms of feedback and control over information released. I describe a framework for design for better self presentation and for privacy in ubiquitous computing environments and conclude with examples of its application. --------- Information on the MICE seminars kept up to date in the URL http://www.cs.ucl.ac.uk/mice/seminars/ which should also contain archive material (audio and slides).

The version of this module included in the ms2 patch on the SunOS 4.1.3U1 Rev B CD has problems and causes the symptoms you have experienced. You should get the 101508-06 sun4m Jumbo patch with has a newer version of the audio_4231.o module. This is available on sunsolve1.sun.com. However, it still has some problems. Namely, I've experienced frequent loud popping sounds in the output when using it with vat. Also, I've experienced a couple of hard hangs of the machine after the audio driver complained of "DMA_SETUP" errors. -Larry Blunk Merit Network, Inc.

On July 16th, the first fragments of the shattered Comet Shoemaker-Levy 9 will hit Jupiter at 130,000 miles per hour. Each impact will have the explosive force of 200,000 H-bombs. Your guides to this astronomical event will be MIRA astronomers, who will join you in seeing these images for the first time. This event is so unprecedented that scientists have almost no idea what will happen. Speculation includes superheated bubbles of 100,000 degree gases bursting out of the lower, previously unseen depths of Jupiter's dense atmosphere and the possibility of high speed jets of material shooting back into space, perhaps even forming new rings around the giant planet. The speakers and other astronomers from the MIRA staff will be available throughout the evening for questions and discussion with the guests. Illustrated Mini-Talks by: Dr. William Hayden Smith, renowned planetologist and professor of Earth & Planetary Sciences at Washington University, St. Louis, MO, on the effects of comet collisions on our weather. Would the earth's atmosphere survive a comet crash? Dr. David Cudaback, professor emeritus at UC Berkeley, and expert on comet and meteor impact sites and Nemesis, a hypothetical red dwarf twin of our sun, whose close approach to the solar system every few million years would unleash a deadly comet storm. Did a comet wipe out the dinosaurs? Dr. Wm. Bruce Weaver, MIRA's Director of Research, on the discovery of the comet and its extraordinary fate, including the best pictures from observatories around the world of the last few weeks of the comet's life. Thomas Logan, MIRA, an Egyptologist and historian, on the importance of comets on ancient civilizations and the fall of civilizations due to ecological catastrophes. Dr. Russell Coile, Pacific Grove Fire Dept. An expert on disaster planning will answer what would happen to a city after a comet impact. How would you cash a check after a comet impact on earth? A panel discussion will complete the evening, summarizing the first impressions of the scientists to this unprecedented event.

Ian's depends on where the congestion lies w.r.t the sender... exceptions: 1/ when the group is sparse 2/ if the congestion is distributed weirdly 3/ if the randomisation of session messages in groups and subgroups (i.e. receivers in similar localities w.r.t cngestion) is poor (very possible!). we suggest both schemes operate - they both inmprove things, and as far as we can tell, neither does any harm. we believe there may be some nasty second order congestion situations (e.g. rate of change of congestion is high) where both schemes hae trouble... we are going to try an analysis to see what randomneFrom rem-conf-request@es.net Sat Jul 16 23:18:33 1994 Received: from taurus.cs.nps.navy.mil by osi-west.es.net via ESnet SMTP service id <03529-0@osi-west.es.net>; Sat, 16 Jul 1994 20:17:53 +0000 Received: by taurus.cs.nps.navy.mil (4.1/SMI-4.1) id AA02141; Sat, 16 Jul 94 20:19:47 PDT Date: Sat, 16 Jul 94 20:19:47 PDT From: brutzman@cs.nps.navy.mil (Don Brutzman) Message-Id: <9407170319.AA02141@taurus.cs.nps.navy.mil> To: rem-conf@es.net Subject: MBone broadcast: AUV 94 tues/wed This tuesday and wednesday we hope to broadcast selected sessions from the IEEE Oceanic Engineering Society conference Autonomous Underwater Vehicles (AUV) 94 live from Cambridge Massachusetts.

I'm sorry I am very sorry, but the planned MBONe broadcast of the comet impact did not take place because our bridge was saturated with traffic from the MBONe broadcast of the shuttle flight. I am sorry that I did not publicize this as soon as I knew about it. Since I did not recieve any email from the MBONE community announcing your intentions to watch, I didn't think anyone would b joining us. Therefore, I did not assign a high priority to having someone post the news that the broadcast had been cancelled. I do apologize for any inconvenience this may have caused you, we really tried our best to make e MBONE happen. When we can filter MBONE traffic, then we can do this kind of thing even during another MBONE broadcast.

Version 3.3 beta of the 'nv' network video tool is now available. This version is completely upward and downward compatible with the previous (3.2) release when sending nv format video, but it has a number of new features, and runs on additional platforms. At the moment, I don't have binaries built for all the platforms, but I hope to be collecting those over the next week or so. In addition to the sources, binaries are available now for SPARCstations running SunOS 4 and SunOS 5 (Solaris 2.x), and SGIs running Irix 5.2. The files are on parcftp.xerox.com in /pub/net/research: -rw-r--r-- 1 frederic parc 723433 Jul 18 18:14 nvbin-3.3beta-irix5.tar.Z -rw-r--r-- 1 frederic parc 934947 Jul 18 18:13 nvbin-3.3beta-sunos4.tar.Z -rw-r--r-- 1 frederic parc 720426 Jul 18 18:14 nvbin-3.3beta-sunos5.tar.Z -rw-r--r-- 1 frederic parc 301885 Jul 18 18:13 nvsrc-3.3beta.tar.Z The complete list of platforms & grabbers supported is as follows: SPARC/SunOS 4 Parallax, PARCVideo, VideoPix, X11 SPARC/SunOS 5 SunVideo, VideoPix, X11 SGI/Irix 5 SGI VL (Indy, Galileo), X11 DEC 5000/Ultrix PIP, X11 DEC Alpha/OSF 1 J300, X11 HP9000/HPUX VideoLive, X11 RS6000/AIX IBM VCA, X11 In addition, the program may compile on other UNIX systems that support X11, Tcl/Tk, and BSD sockets with just the X11 grabber enabled. I'd be happy to accept binaries for any such system to be put up on the FTP site. Here's a summary from the CHANGES file of what's new in 3.3: The internal interface to grabbers was restructured to allow a single nv binary to support more than one grabber type. Several new grabber modules were also added, including the Parallax XVideo and SunVideo boards on the Sun, a generic Video Library grabber on the SGI, the J300 board on the DEC Alpha, the RasterOps VideoLive board on the HP, and the IBM VCA board on the RS6000. In addition, a generic X11 screen grabber module was added that should work on all platforms. Decode support has been added for Sun CellB format video and the proprietary ViewPoint CPV video. Support for multiple encoders has been added, so nv can now transmit any of its original format, Sun CellB, or Cornell's CU-SeeMe video. Three different transmit sizes are now available, allowing quality to be traded off for frame rate. At the small size, much higher frame rates are possible at a given bandwidth. The large size is useful when sending very detailed images such as slides. Features specific to a particular grabber can now be controlled using a new grabber control panel which can be brought up in the main nv window. This allows nv to control things such as which video input to use. A new "Receive Defaults" panel now allows you to see and change the default settings for brightness, contrast, size, and color settings for new video sources which are received. These options can now also be set with command line switches and/or X defaults. Several major user interface changes were made in this release. A menu bar was added at the top to get at an info panel, select from the set of grabbers supported, select from the set of encodings supported, and add/remove subpanels in the main nv window. When colormap space isn't available in the default colormap, nv will now allocate a private map. It tries to some extent to reduce colormap flashing on systems which can only install a single map at a time, but some amount of that is unavoidable. For images to look correct on those systems, the mouse much be somewhere in one of the nv windows. Systems with multiple network interfaces should now be handled better even without the use of the "-interface" option. -- Ron Frederick frederick@parc.xerox.com From rem-conf-request@es.net Mon Jul 18 16:31:17 1994 Received: from mailhost.lanl.gov by osi-west.es.net via ESnet SMTP service id <10309-0@osi-west.es.net>; Mon, 18 Jul 1994 13:30:42 +0000 Received: from rust.lanl.gov by mailhost.lanl.gov (8.6.8.1/1.2) id OAA21060; Mon, 18 Jul 1994 14:30:37 -0600 Received: by rust.lanl.gov (NX5.67c/NX3.0S) id AA11635; Mon, 18 Jul 94 14:30:37 -0600 Date: Mon, 18 Jul 94 14:30:37 -0600 From: Dick Phillips Message-Id: <9407182030.AA11635@rust.lanl.gov> Original-Received: by NeXT.Mailer (1.87.1) PP-warning: Illegal Received field on preceding line Original-Received: by NeXT Mailer (1.87.1) PP-warning: Illegal Received field on preceding line To: rem-conf@es.net Subject: newer version of SGI wb?

PRESENCE presents startling investigations into major technologies that look torward a time to come. Teleoperators and virtual environments project one or more individuals into new, interactive surroundings by means of electromechanical interface devices - helmets, goggles, earphones, gloves, suit. A person's sense of presence depends upon each interface's character - how distinctly her gloves allow her to feel an environment's curves - and also upon the character of the surroundings, real or virtual, into which she is projected.

I've been promoting an idea to several vendors and associates who have encouraged me to write it up. Although not precisely responsive to the issues here, it seems it may be relevant. Anyway, here it is: Why not run ATM cells in Ethernet frames? Background: At Cornell, we have over 8000 ports of 10BASE-T ethernet installed, going to 10,000 by the end of another year. We want to get ATM to all of those desktops as soon as possible. Solutions being offered or proposed by various vendors promise 25Mbps or 51Mbps or more, but the most optimistic pricing I've heard, projecting for a year or two in the future is about $3-400/port on a mux plus $2-300 for the workstation adapter. Well, that means $5-700 per desktop or $5-7,000,000 for our 10,000 desktops. No way will we be able to afford that much. Also, some of those destop systems have built-in ethernet and no slot for a new ATM adapter. So, my proposal to prospective vendors is: build a 24-port mux (10BASE-T ports) with a 155Mbps ATM port to connect via fiber to a switch. Price it so that the volume discounted cost for us is $100/port, and we will buy approximately 10,000 ports. I think there are probably many campuses with similar needs. Here is how it should work: 1. The mux needs to be as simple as possible to make the cost target. So it should do as little as possible. 2. Rule 1. -- Only one node (workstation) on a port, so it is a point to point link. No contention, no collisions, etc. 3. AAL is done in software at the workstation (a new driver); SAR is distributed between the workstation and the mux (see below). 4. The UNI is available via appropriate API to Native-mode ATM applications. IP etc. run over ATM in *exactly* the same way they do with the 25Mbps etc. desktop solutions. The same native atm applications run, although not as fast, of course with only half-duplex 10Mbps available. Performance will be cpu-limited also for some workstations, but remember it is only 10Mbps. 5. A minimum size ethernet frame is 64 bytes with a 46 byte payload which means that the minimum frame for a cell would be 66 bytes, unless some games were played such as use the type bytes for payload. 6. How about the cell header? Implement the mux as a promiscuous listener. For frames sent toward the mux, put the cell header in the ethernet destination address. Perhaps the mux can calculate the HEC to offload the workstation a little. For frames sent by the mux toward the workstation, the cell header goes in the source address. 7. Rule 2. -- More than one cell payload can go in a frame, but they must all be for the same VC; hence they all have the same cell header; hence the cell header only needs to be supplied once, as above. There is no overhead on the wire for sending data as cells. There is very little compute overhead for the workstation to perform the SAR. 8. For workstation originated data, the workstation can trade off efficiency versus latency by choice of how many cells to put in a frame. 9. For data coming in from the ATM switch and being sent on the ethernet link in frames by the mux, there will (possibly) need to be some signaling at VC setup to set parameters for how the mux frames the cells. The mux, receiving a cell from the high-speed link can dally to see if another for the same VC arrives "soon enough" to be packaged in the same frame. There can be a max number of cells before sending the frame. 10. VC's connecting ports on the same mux could have cells (frames?) switched internally in the mux or they could simply be sent as usual on the high-speed link so the switch at the other end can send them back. Probably it's more important to keep the cost of the mux down by keeping it simple than it is to economize on bandwidth used on the link to the switch. Other comments: This proposal is an alternative to ethernet frame switching, which seems costly, and to several other forms of "preserving investment in the installed base." We've spent the last 5 years getting those 10,000 folks hooked up, learning to operate it, manage it, etc. The next step needs to be directly to ATM to the desktop for everyone. Whether to use such an infrastructure to do LAN emulation, or (my favorite) router emulation for existing applications can be debated in exactly the same terms as for the 25Mbps, 51Mbps, etc. solutions. What about performance? For someone converting from a shared ethernet, they should see a 10 or 20 fold improvement, depending on many things. They should also benefit greatly from being able to get QoS facilities, especially for low bandwidth services such as voice. It should be possible to transmit middle-resolution MPEG at 6 Mbps, unless the workstation is a lower-end PC. Anyway, the point is to get early, massive deployment, affordably. I assume we would also be using the 25Mbps or 51Mbps solutions for those able to afford more $. In effect, being able to show folks the benefits of ATM to the desktop may help to sell them on the need for greater speed.

We want to get ATM > to all of those desktops as soon as possible. I think ATM for the sake of ATM should not be a goal. You are setting yourself up to waste a lot of money with little or no benefit over alternatives. If a goal is to continue to provide high quality data access, then stick with routed IP of 10baseT at $0 incremental cost. ATM will not buy you anything here and will actually worsen your IP performance. The existing TCP congestion control is a much better means of utilizing available bandwidth than resource reservation could ever be and is superior to anything I've seen proposed for ATM traffic management of ABR service. If real time applications such as voice are a concern, track the progress in RSVP and deploy RSVP capable software in routers and hosts as it becomes available and where reservations for real time traffic are needed. This again may be a $0 cost solution if software can be upgraded at no cost. Then and only then, if certain hubs are a congestion point, dealing with that problem can be much cheaper than trying to do funny ATM over ethernet things. A combined router/hub which can treat each 10baseT segment as an individual subnet might be a better solution. You can then have 51 or 155 mb/s into the router/hub using IP over ATM and dozens of 10 mb/s segments (totaling way over 155 mb/s). RSVP can nail up bandwidth for the apps that need it and TCP can do it's usual good job of high utilization and equitable sharing of the remaining bandwidth including bandwidth that real time apps thought they needed but never really used (often 80-90% of what they allocated if compression is applied, since compressed audio and video are both highly bursty). Current ATM products try to replace your hub and group them into logical LAN Emulation bridged subnetworks. A router somewhere in the picture can be used to talk directly to the LAN emulation protocol and establish a very large number of bridging relationships (essentially one on one) to accomplish the same thing described above. If RSVP is implemented, a router understanding both RSVP and the LAN Emulation protocol will be able manage bandwidth by adjusting LAN Emulation VC reservations queueing real time IP frames ahead of elastic traffic (TCP). This LAN Emulation based solution seems to be the immediate direction of things for hub replacements - though many pieces are still in the works (the least of which may be RSVP). Strict bandwidth reservation is a loser, especially if bandwidth is not practically infinite, as would be the case with ATM over 10baseT. Doing things over native ATM loses you internetworking capability as well. If ATM is not ubiquitous for a long time, going native ATM will severely limit your connectivity.

I realize that some people won't see this message before the IETF meeting, but I include it here for the benefit of those who will not be attending. I'll bring up the topic at the meeting as well. Christian argued that QoS feedback control for both the multicast and unicast schemes is still experimental. I agree with that and I think experimenting with a variety of mechanisms is important to really understand the problem. Of course, it is equally important to make sure the ideas being tested will scale and not melt the MBONE before they are unleashed on the world (e.g., it is critical to select conservative defaults and to try to anticipate the behavior of naive users). As Henning pointed out, for the purpose of experimentation in the case where there are no translators or bridges, one can certainly send unicast packets from receivers directly back to the source. There are a number of questions to be answered: - What should be the destination port of the unicast reverse packet? Possibilities are: - The RTCP port of the session, though there could be problems with binding sockets to multicast and unicast addresses - The source port from which forward RTCP packets are sent by the source to which the unicast packet is now being returned (this is roughly the scheme that was used in RTPv1). - What format should the unicast reverse packets have? If they go to the RTCP port and might be mixed with multicast packets, then they probably need to be in RTCP format. - Do the unicast packet need to contain some identification (SSRC or CNAME) of the source to which the unicast packet is sent (that's what SDST used to provide in RTPv1)? Now, how about generalizing this mechanism to work with bridges and translators? First, I think there was some confusion in the earlier discussion. Bridges are application-level relays that combine the traffic from multiple sources and regenerate the data with new timing, so they become the synchronization source for packets they send on. Even in RTPv1, reverse packets were delivered to the synchronization source and did not flow through bridges. If you think about it, this makes sense: for the example of a bridge that mixes a bunch of incoming PCM streams and sends out one compressed GSM stream, it might not be meaningful to pass through a report about the quality of reception of the GSM stream back to the PCM sources. It is likely that the bridge will have to do some application-specific processing of report information, and then generate new report information on the other side. That applies to multicast or unicast reporting. On the other hand, translators do not modify the data; they only pass on the packet to a different address or perhaps with a different underlying protocol. One example is the translation from a multicast address to one or more unicast addresses for end systems that are not multicast capable. In RTPv1, translators kept a table to map from a locally assigned SSRC identifier back to the network address and port from which a particular source's traffic came. The table was also used in the forward direction to get the SSRC id to insert. In RTPv2, there is no need for that table in the forward direction because the SSRC id's are globally unique and are always present. If experiments show the reverse packets to be an important function, then translators could be required to build a table from the forward packets and use it for the reverse packets, as Henning noted. However, there is a gotcha that was not mentioned in the earlier discussion: If the RTP and RTCP packets are encrypted, then the translator won't know what the SSRC is and will have no information from which to build the table or to do the mapping. -- Steve ------- From rem-conf-request@es.net Sat Jul 23 05:40:54 1994 Received: from cs.tut.fi by osi-west.es.net via ESnet SMTP service id <10300-0@osi-west.es.net>; Sat, 23 Jul 1994 02:40:18 +0000 Received: from kaarne.cs.tut.fi (mit@kaarne.cs.tut.fi [130.230.3.2]) by cs.tut.fi (8.6.9/8.6.4) with ESMTP id MAA28275 for ; Sat, 23 Jul 1994 12:41:55 +0300 From: Tsokkinen Mikko Received: (mit@localhost) by kaarne.cs.tut.fi (8.6.8/8.6.4) id MAA14458; Sat, 23 Jul 1994 12:40:12 +0300 Date: Sat, 23 Jul 1994 12:40:12 +0300 Message-Id: <199407230940.MAA14458@kaarne.cs.tut.fi> To: rem-conf@es.net Subject: Jazz Broadcast Repost with Artist Information We will be broadcasting a worldwide live jazz concert from Pori Jazz. Concert is titled: Lalo Schifrin Quartet & Turku Philharmonics - "Jazz Meets Symphony" Argentina born Lalo Schifrin (62) is best known for his many award winning movie soundtracks -- for instance Dirty Harry, Cool Hand Luke, Mission Impossible -- that number over 100 if his tv works are also counted. Jazz and classical music have always competed equally for the love of the pianist who now works as a conductor of Los Angeles based Glendale Symphony Orchestra. Schifrin has played and recorded with Quincy Jones, Sarah Vaughan, Count Basie and Stan Getz not to mention Dizzy Gillespie who in the 50's, upon hearing Lalo play, immediately wanted him to be his pianist. On his recent Jazz meets The Symphony album (East West) the master composer, with bassist Ray Brown, drummer Grady Tate and the London Philharmonic, tips his hat to his favourite composers/compositions with typically elegant arrangements. In Pori the maestro conducts the Turku Philharmonic while reedsman James Morris makes Lalo's trio into quartet.

In the NACK, FIR packets case used in ivs, I'd rather choose the source port from which data packets are sent by the source. Indeed, these packets are directly used by the video coder process without any control/session pass. However, the session manager will avoid/allow the use of these packets according to the current number of participants in the conference.

This version is completely upward and downward compatible with the previous (3.2) release when sending nv format video, but it has a number of new features, and runs on additional platforms. At the moment, I don't have binaries built for all the platforms, but I hope to be collecting those over the next week or so. I have just built a DEC OSF/1 2.0 version of nv 3.3beta which is available for anonymous ftp as ftp://ftp.adelaide.edu.au/pub/av/AXP/nvbin-3.3beta-osf1.tar.Z This is a non MME version and so unless you have jv2driver and a J300 you won't be able to send video but it should be good enough to use to watch the IETF. I will build a MME version once I have a valid MME PAK again :-). I'm not sure if this will work on version 1.x of OSF/1 but I can probably build a kit if anyone is desperate. Mark.

You might see if you can track him before the meeting, and see what he's prepared. I will get into town late Tuesday evening. I am in town for some other meetings regarding our ATM projects in Canada, but would be more than happy to talk to any of the groups regarding multimedia related activities in the LMSC. I've reserved all of Wednesday morning,11am to 2:30 pm Thursday, and (if required) Thursday evening if we can schedule anything. If we can't schedule a presentation time, I will attempt to track down interested partieson my own.

This points out a difficulty, though -- that choice is good for your application because of the particular software architecture. Another application might make a different choice. Therefore it seems that for the protocol to specify one choice would be a problem. It might be necessary to have a control message to specify the port number for receivers to use (we had something like this in a much earlier version of the protocol). As I mentioned, there are several details that should be worked out as part of the preparation for experimenting with a reverse unicast path in RTPv2, and this would be one of them. -- Steve ------- From rem-conf-request@es.net Wed Jul 27 04:57:28 1994 Received: from bells.cs.ucl.ac.uk by osi-west.es.net via ESnet SMTP service id <27749-0@osi-west.es.net>; Wed, 27 Jul 1994 01:56:45 +0000 Received: from rodent.cs.ucl.ac.uk by bells.cs.ucl.ac.uk with local SMTP id ; Wed, 27 Jul 1994 09:55:39 +0100 To: rem-conf@es.net Subject: mbone congestion, admin scoping Date: Wed, 27 Jul 94 09:55:36 +0100 Message-ID: <706.775299336@cs.ucl.ac.uk> From: Jon Crowcroft last nite on UK television, the polcice showed a tour of their video surveillance around london (for non-UKers, there's a signalem strike a tthe moment, so trains aren't running) it occured to me that putting all these cameras as mbone sources would be really useful but you'd want a) very good pruning or sparse mode PIM b) very good admin scoping to stop random trawlign around of all the camera sources... anyhow, just another thing to stress the MboneNg... jon From rem-conf-request@es.net Wed Jul 27 13:18:41 1994 Received: from POSTOFFICE3.MAIL.CORNELL.EDU by osi-west.es.net via ESnet SMTP service id <29020-0@osi-west.es.net>; Wed, 27 Jul 1994 10:18:12 +0000 Received: from [142.1.1.209] (pc-109.ietf.utoronto.ca [142.1.1.209]) by postoffice3.mail.cornell.edu (8.6.5/8.6.5) with SMTP id NAA09654; Wed, 27 Jul 1994 13:17:55 -0400 Message-Id: <199407271717.NAA09654@postoffice3.mail.cornell.edu> X-Sender: swb1@postoffice3.mail.cornell.edu Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Date: Wed, 27 Jul 1994 13:19:28 -0500 To: Jon Crowcroft , rem-conf@es.net From: Scott W Brim Subject: Re: mbone congestion, admin scoping Yup.

LA has it. They have two versions: cameras mounted by local TV stations you can see during the AM traffic annoucements on half-hour intervals an "animated" display of road congestion on a cable channel during rush hours (i.e., nearly 24-hour) Joe From rem-conf-request@es.net Thu Jul 28 04:29:58 1994 Received: from sirius.brunel.ac.uk by osi-west.es.net via ESnet SMTP service id <02189-0@osi-west.es.net>; Thu, 28 Jul 1994 01:29:23 +0000 Received: from babbage.brunel.ac.uk by sirius.brunel.ac.uk with SMTP (PP) id <04251-0@sirius.brunel.ac.uk>; Thu, 28 Jul 1994 09:29:05 +0100 From: Andrew Findlay Message-Id: <10200.9407280829@babbage.brunel.ac.uk> Subject: Re: mbone congestion, admin scoping To: swb1@cornell.edu (Scott W Brim) Date: Thu, 28 Jul 1994 09:28:59 +0100 (BST) Cc: rem-conf@es.net In-Reply-To: <199407271717.NAA09654@postoffice3.mail.cornell.edu> from "Scott W Brim" at Jul 27, 94 01:19:28 pm X-Mailer: ELM [version 2.4 PL21] Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Length: 1057 >Yup.

The UK has a company called TrafficMaster which has sensors on almost every motorway in the country and also on main approach roads to London and some other cities. They supply a graphics pager (!) which displays a map with current traffic speeds and other traffic news. Makes more sense than cameras in many ways - the sensors are small battery-powered things fixed to bridges over the road, and they report back to base using a public packet-radio system when they detect trouble.
