Area Summary reported by Stev Knowles/FTP Software
The following BOF and working groups met during the November IETF
meeting in Houston:
o Whither ATM - An Update BOF (ATMINFO)
o Dynamic Host Configuration Working Group (DHC)
o Internet Stream Protocol V2 Working Group (ST2)
o IP Over Asynchronous Transfer Mode Working Group (ATM)
o IP Over Large Public Data Networks Working Group (IPLPDN)
o Point-to-Point Protocol Extensions Working Group (PPPEXT)
Whither ATM - An Update BOF (ATMINFO)
An information only BOF was held on ATM technology and on developments
since the Amsterdam IETF meeting.
o 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.''
o Eric Hoffman gave a presentation, on behalf of Allison Mankin and
Maryann Perez, on the problems of implementing ATM standards.
o Mike Goguen gave a review of the work of the ATM Forum's Private
NNI Working Group.
o The ATM Forum UNI 3.0 Specification is out and available.
Internet Stream Protocol V2 Working Group (ST2)
ST2 met for the first time at Houston in two sessions. The first
session involved a brief review of the charter, presentations on ST-II
experience from BBN and ARPA, and an overview of the IBM ST-II
implementation. After the presentations, discussion was started on
which portions of the protocol need revision, removal, or clarification.
The second session was a more detailed working session in which details
of State Transition diagrams, groups of streams, and the join/leave
mechanism were discussed. The group also selected Lou Berger, Steve
DeJarnett, and Luca Delgrossi as the document editors for the
Internet-Drafts and RFC, and decided to issue a further call for writers
over the mailing list. An interim meeting may be held in January to
write the initial Internet-Draft.
IP Over Asynchronous Transfer Mode Working Group (ATM)
The Classical Internet-Draft Last Call closed on Monday, November 1.
All issues raised during the Last Call process were dealt with and
closed. One serious technical issue was raised by Dave Sincoskie
regarding the arp table entry timeout and n*n InARP transmission
characteristics. A paragraph change was presented and adopted by
consensus at the Thursday meeting. Dave Piscitello approved the change
process; another Last Call is not needed. The changed paragraph will
appear in the meeting minutes. The document is awaiting IESG ballot.
Joel Halpern gave a presentation of the Routing Over the Large Clouds
Working Group (ROLC) proposed charter. Ran Atkinson presented his MTU
draft. Bob Cole led a discussion of the framework document. The chair
hopes that this document can be turned into a planning guide for the
working group.
The working group hosted other discussions on security, source address,
the non-optimal behavior of InARP, selectors and multiple LISs,
application binding, and Q.93B parameters. One discussion item, the
issue of IP over the ATM Forum's LAN Emulation specification, was not
completed.
IP Over Large Public Data Networks Working Group (IPLPDN)
The purpose of re-opening the IP over Large Public Data Networks
(IPLPDN) working group was to clean up some unresolved items, and attend
to those items which have come up after the group became inactive.
o Keith Sklower presented summaries of the ``Determination of
Encapsulation of Multi-protocol Datagrams in Circuit-switched
Environments'' and ``Parameter Negotiation over Frame Relay''
Internet-Drafts.
o The draft for the updates to RFC 1315 has expired. Caralyn Brown
has agreed to repost it and set the wheels in motion to get it
forwarded.
o Joel Halpern and Fred Baker volunteered to write an Informational
document covering experience in partial mesh networks. The
document will be posted on the mailing list and discussed there.
o The group decided that the definition of InARP for IPX might better
be handled by Novell.
o During the IP over ATM discussions, it was felt that InARP was not
robust enough. The group decided that because this problem was
related to ATM's ARP server, the ATM group should pursue this work.
o Those who were most interested in IEEE 802.5 Source Routing over
Frame Relay were not present at the meeting. It was decided that
this should be taken to the mailing list for further discussion.
Point-to-Point Protocol Extensions Working Group (PPPEXT)
Two documents were referred, without discussion, to the IESG for
consideration as Proposed Standards.
o ``PPP over ISDN'' (draft-ietf-pppext-isdn-03.txt)
o ``PPP over SONETE/SDH'' (draft-ietf-pppext-sonet-01.txt)
There was discussion about ``PPP over X.25''
(draft-ietf-pppext-x25-02.txt) and it was decided that the document
should be recommended to the IESG for consideration as a Proposed
Standard.
``PPP in Frame Relay'' (draft-ietf-pppext-frame-relay-02.txt) was also
discussed. It was recommended that a single sentence be added, and that
the resulting Internet-Draft, draft-ietf-pppext-frame-relay-03.txt, be
considered by the IESG as a Proposed Standard.
It was recommended that ``PPP LCP Extensions''
(draft-ietf-pppext-lcpext-04.txt) be considered by the IESG as a
Proposed Standard. Another document will be drawn up describing the LCP
option for negotiation of encapsulations.
Dave Rand presented the ``PPP Reliable Transmission'' document,
(draft-ietf-pppext-reliable-00.txt). After some discussion, the
document was recommended for consideration by the IESG as a Proposed
Standard.
Several other documents were presented and discussed.
