1. The minutes from the July 11 and July 18 teleconferences were
   approved. Coya will place in the shadow directories.

2. Ross Callon has a draft IPNG WG charter, and will send it to the
   directorate for review.

3. There is a need for an overview to compliment the SST Overview
   transition plan, including a description of when IPv6 addresses are
   needed. Allison asked for volunteers to write a review of the SST
   overview section. Ross Callon volunteered to perform a review and
   send comments to the relevant individuals.

4. Dave Clark reported that they (MIT) had received between 35-40
   requests for information and/or directions for the IPng walkthru.
   Paul Mockapetris (ISI) and Steve Deering (Xerox Parc) reported
   getting 3-7 requests each.

   Use of White Board technology during the presentation is planned by
   a number of folks. This implies a need to get presentations ready
   via Postscript prior to the meeting, and it was suggested that
   copies of the presentation slides be sent to all sites.

5. The proposed schedule for Aug. 22 IPng walkthru is as follows:

	Mankin/Bradner		Introduction
	Deering 		IP6 Protocol
  	Deering 		IP6 Routing and Addressing
  	Katz			IP6 Autoconfiguration
  	Atkinson		IP6 Security
  	Hinden	 		IP6 Transition
	All			Q&A
 

   Allison will work on the agenda and get it to Paul Mockapetris, who
   will then send it out to the IETF.

6. Yakov reported that the addressing architecture document is now
   available as an I-D, and that he and Peter Lothberg are working
   on a provider-based addressing document.

7. Bob Hinden is working on a high level overview of SIPP-16 addressing
   along with a roadmap from here to there (includes mappings to other
   protocol suites).

ALLISON/SCOTT

   The following items are from Dave Clark's discussions which,
   as I recall, was started with the understanding that this was
   for the directorate only. I don't recall when the pen was
   supposed to go down, or if I accurately captured the main points
   of discussion. I've included these notes for three reasons:

	1. So you'll no I wasn't asleep :-)
	2. So you can decide whether they are to be included in
	   the minutes or not (on an item by item basis)
	3. If #2 is yes, did I get them right?


8. There was a discussion focusing on how to get router vendors, host
   vendors, and service providers on the IPv6 bandwagon, and avoid the
   resistance of some to wait until the transition plans are either
   better defined or underway before they commit to producing IPv6
   products, and to avoid unstandardized retro-fitting of IPv6 features
   into IPv4 applications and a host of NAT boxes.

9. It was stated that attention needs to be given to the performance of
   IPv6, especially the case where source domain routing might be
   encapsulated in the IPv6 header, and to take advantage of header
   compression to address concerns that 16 byte headers can/will/might
   slow down processing, or be processed inefficiently.

10. Do certain items, such as hop-by-hop flows, need to be
    included/ specified by December? Can these items wait until more
    experience is gained with Ipv6 AND the items themselves?

    What is the balance between the requirement to specificy IPNG by
    the December committment date vs. including items that, if not in
    the spec, may never happen.

11. It was noted that the SDR working group is working on source domain
    routing with IPv6, but there was concern that it was being done
    outside of the IPNG Working Group and "outside the Directorate's
    perception" (i.e. not all were aware of the work being done).
