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 Philip Almquist was not able to attend this meeting. Discussion was postponed until February 6th. 3.2 Appletalk Tunneling 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 It is slated to become an Apple standard and is expected to be withdrawn from consideration from the IESG.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 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 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 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 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 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 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.
