MINUTES
-------

1) Administrivia

1.1 Bash the Agenda

The agenda was well bashed, with the addition of several more
protocol and technical management actions to this over-full agenda.
Due to the lack of time available for such a full agenda, the IESG
discussed new working group formation, Packet Audio, and then
protocol actions. Most technical management issues and review of the
earlier minutes were not undertaken.

1.2 Review of the Minutes

A review of the minutes was deferred until a future meeting. The
IESG discussed the possibility of meeting weekly for the following
few weeks to clear up a backlog of work.

1.3 Next Meeting

The next IESG meeting will be held February 6th, 1992.

3) Protocol Actions

3.1 Type of Service in the Internet
<draft-almquist-tos-02.txt>

Philip Almquist was not able to attend this meeting. Discussion was
postponed until February 6th.

3.2 Appletalk Tunneling
<draft-ietf-appleip-aurp-02.txt>

The current version of this document will not become a proposed
standard. It is slated to become an Apple standard and is expected
to be withdrawn from consideration from the IESG.

ACTION: Vaudreuil -- Communicate the withdrawal of AURP from standards
consideration to the IETF.

3.3 TCP-LW
<draft-ietf-tcplw-tcpext-01.txt>

There is a small snag that appeared in the TCP document. There is
concern over the particulars of the SAC option. The last call
scheduled to be send will delayed until this issue is resolved.

3.4 UCP Trouble Ticket Wishlist
<draft-ietf-ucp-tt-01.txt>

This is a private document from Dale Johnson, however it have
received a lot of comment from the UCP group. The IESG briefly
discussed this and agreed that publication is long overdue.

POSITION: The User Connectivity Trouble Ticket Wishlist should be
published as an informational RFC.

ACTION: Vaudreuil -- Send a "Notification" to the RFC Editor that the
Trouble Ticket wishlist document is ready to be published as an
informational RFC.

3.5 RFC 822 Message Extensions
<draft-ietf-822ext-messagebodies-03.txt>
<draft-ietf-822ext-msghead-01.txt>

Due to lack of time, discussion on these documents was deferred. An
offline discussion between Russ Hobby, Dave Crocker, and Greg
Vaudreuil was scheduled to identify points of interest for the
IESG.

3.6 SMDS to Draft Standard

3.6.1 The Transmission of IP Datagrams over the SMDS Service
<RFC 1209> to Draft Standard

No information on the implementation and deployment status of RFC
1209. "The Transmission of IP Datagrams over the SMDS Service" has
been received. Action was deferred until this information is
available to the IESG.

3.6.1 Definitions of Managed Objects for the SIP Interface Type
<draft-ietf-snmp-smdssipmib-06> to Proposed Standard

This document was approved by the IESG. The recommendation to the
IAB will be sent with the SMDS document when it is ready.

3.7 Network Fax
<draft-ietf-netfax-netimage-02.txt>

Discussion on this document was deferred due to lack of time.

4) Technical Management Issues

4.1 User Friendly Naming

Dave Crocker gave a brief report on the status of the effort to
resolve questions raised by the IAB to the X.500 User Friendly
Naming document. The assigned action items are actively being
pursued.

4.5 Video transmission of IETF meetings

Steve Casner and Steve Deering joined the IESG teleconference to
discuss the possibility of using packet audio and multicast to allow
broadcast of the plenary sessions over the Internet. Steve Deering
was patched into the conference by packet voice over the Dartnet.

The technology demonstrated by Deering and Casner during this
meeting requires IP tunneling through non-multicast IP routers. A
limited pilot demonstration can be established by designating
specific multicast "exploder" routers. The IESG was interested in
knowing if this pilot would be widely publicized as a general
service or limited to a select few people.

ACTION: Gross, Coya -- Investigate the possibility and nature of
establishing a "Pilot Experiment" of broadcasting IETF meeting plenary
audio via UDP multicast.

ACTION: Gross -- Investigate the possibility of putting multicast
software on the ANS UNIX based Routers for the July IETF meetings.

5) IESG Technical Evolution Document.

Discussion of the IESG Technical Evolution document was deferred
until a future meeting due to lack of time.

6) New Working Group Actions

6.1 MHS-DS

X.400 flat level 7 routing tables are growing too large to be
maintained and distributed. The X.400 pilot is in danger of
collapsing due to the excessive size. To continue, a directory based
system is needed in the near term. Work is going on in the CCITT on
this topic, but, there is a feeling that this may be too little to
late. CCITT folks have been invited to participate in the Working
Group.

This Working Group will focus on getting X.500 directory services
applied to the X.400 pilot. European production X.400 systems have
been dealing with this problem as well, and coordination will be
sought. The Working Group is co-chaired by an North American and a
European.

ACTION: Vaudreuil -- Announce the MHS-DS working group to the IETF.

6.2 Routing Information Protocol

Gary Malkin has a desire to update RIP to allow it to handle
security, and subnet masks to serve for small domains. A BOF was
held and the community expressed interest in this effort. Bob Hinden
and Noel Chiappa agree that this effort has merit and should
proceed.

The IAB members on the IESG-TECH mailing list have been notified
that the IESG is considering this working group. The IAB is likely
to push back on this effort in terms of the evolving the addressing
and routing architecture. The IESG chair anticipates eventual IAB
approval of the effort provided the protocol meets the requirements
for modern routing protocols. There is a rational reason for a
small scale routing protocol.

Dave Crocker proposed that the IAB be asked for explicit buy-in on
each working group. The idea is that if the IAB approves the
working group, then it does not have basis to reject the work
product of that working group on architectural grounds. The IAB
still exercises a final quality control check on any standards
document. The IESG rejected the notion that the IAB needs to approve
the IESG action, however the IESG will actively solicit comments on
the wisdom of a working group from the IAB.

POSITION: Working group proposals should be sent to the IESG and the
IAB rather than just the IESG-TECH mailing list with an explicit
invitation to the IAB to comment upon the Working group before the
IESG approved the working group.

ACTION: Vaudreuil -- Announce the RIP version 2 working group to the
IETF.

6.3 Audio/Video Teleconferencing

This working group grew out of BOF held at the Santa Fe IETF. This
effort aims to align the various experimental video/audio over UDP
protocols to promote interoperability. The Working Group will
attempt define protocols above the transport layer in a manner which
is consistent with migrating to more optimal transport when it
becomes available.

The IESG discussed the scope of this group. The boundary between
research and engineering was explored. There appear to be two
questions. 1) What does the packet look like, and 2) how do you get
it to there. The IESG felt that the current working group focused
on standardizing packet formats and applications was OK.
Exploration of high speed transport is still a research topic.

ACTION: Vaudreuil-- Announce the Audio/Video teleconferencing working
group to the IETF once a new charter reflecting the clear distinction
between packet format and transport is provided to the IESG.

6.4 DS1, DS3 MIB Revision

The DS1 and DS3 mibs are at the Proposed level. On the way to Draft
standard, these documents need some revision. This Working Group is
chartered to revise the Mibs and to coordinate and align with the
IEEE to the maximum degree reasonable.

ACTION: Vaudreuil -- Announce the DS1/DS3 MIB Revision Working Group to
the IETF.
