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.
