CURRENT_MEETING_REPORT_ Reported by Mark Laubach/Hewlett-Packard Minutes of the Whither ATM - An Update BOF (ATMINFO) An information-only BOF was held on ATM technology and developments since the Amsterdam IETF meeting. Many people were appreciative that the BOF was held. Presentations Bryan Lyles presented a summary of ANSI T1S1 activities towards defining a new ATM Bearer Service called ``Class Y'' for variable bit-rate traffic, i.e. ``best effort.'' Various public ATM providers are viewing this a boon as it is a different service than constant bit-rate (CBR) traffic (voice) and can be tariffed differently. T1S1 will be working further to create an implementation independent definition. When adopted in T1S1, it should make it into ITU-TSS and then be adopted by the ATM Forum. Bryan's closing said to ``tune in again in about six months.'' Eric Hoffman gave a talk on behalf of Allison Mankin and Maryann Perez on the problems of implementing ATM standards. Naval Research Laboratory (NRL) has recently released their Q.93B implementation called VINCE into the public domain. In addition, NRL will be implementing the Classic IP and ARP over ATM model. NRL feels the primary ``snag'' with Q.93B lies in the complicated parsing, forced bitfield parsing for rarely used elements, and spurious ordering rules. They do have a working version that is tracking ATM Forum's UNI 3.0 specification. Ports are being done to support several switch architectures. Mike Goguen gave a review of the work of the ATM Forum's Private NNI Working Group. The groups main work is NNI signaling, VC routing, and Q.93B as the basis for the NNI signaling. This working group just started in July. The November ATM Forum meeting will focus on finalizing requirements and beginning a draft reference configuration. Some key requirement areas to be agreed on: o Policy o To what extent in Phase 1 o Hybrid private/public networks o Source routing versus hop-by-hop The ATM Forum UNI 3.0 Specification is out and available. 1 Attendees Masuma Ahmed mxa@mail.bellcore.com Bart Berger bart_berger@3com.com Caralyn Brown cbrown@wellfleet.com Tracy Brown tacox@mail.bellcore.com Theodore Brunner tob@thumper.bellcore.com Ted Chang tchang@atg.wiltel.com Chris Chiotasso chris@andr.ub.com Blair Copland copland@unt.edu Kurt Dobbins dobbins@ctron.com Christopher Dorsey dorsey@es.net David Engel david@ods.com Dario Ercole Dario.Ercole@cselt.stet.it Michael Erlinger mike@jarthur.claremont.edu William Fardy billf@frontier.com Steve Feldman feldman@mfsdatanet.com Robert Fenoglio fenoglio@vnet.ibm.com Mark Garrett mwg@faline.bellcore.com Steve Garritano steveg@kalpana.com Robert Grow bob@xlnt.com Stuart Hale stu_hale@vnet.ibm.com Augusto Ham ahamm@atg.wiltel.com Daniel Hansen danh@ngc.com Juha Heinanen juha.heinanen@datanet.tele.fi Mike Holloway mikeh@newbridge.com Refael Horev horev@lannet.com Frank Kastenholz kasten@ftp.com Mark Kepke mak@fc.hp.com Cheryl Krupczak cheryl@empiretech.com Ted Kuo tik@ececho.ncsu.edu Andrew Malis malis@maelstrom.timeplex.com Keith McCloghrie kzm@hls.com Evan McGinnis bem@3com.com Steven Onishi sonishi@wellfleet.com Zbigniew Opalka zopalka@agile.com David Perkins dperkins@synoptics.com Kenneth Rodemann krr@qsun.att.com Hal Sandick sandick@vnet.ibm.com Michael Scanlon scanlon@ftp.com Jean-Bernard Schmitt jbs@vnet.ibm.com Kanan Shah kshah@cmf.nrl.navy.mil Satya Sharma ssharma@chang.austin.ibm.com Uttam Shikarpur uttam@zk3.dec.com Timon Sloane timon@timonware.com Kaj Tesink kaj@cc.bellcore.com Panos Tsigaridas Tsigaridas@fokus.gmd.de Thomas Walsh Alice Wang alice.wang@eng.sun.com Honda Wu honda@nat.com 2
