CURRENT_MEETING_REPORT_
Reported by Scott Briml/Cornell
AGENDA
1. Report on Europe - Peter Kirstein
2. Report on the Pacific - Torben Nielsen
3. Report on RFC work - Kent England
4. Old and new issues of concern - Scott Brim
5. Internet Cartography Project - Ted Bruner
MINUTES
Coordinating international connectivity has become a significant issue
for this group, first because there are few if any precedents for what
is happening internationally; and second because it is all happening so
fast.
Report on Europe - Peter Kirstein
Peter Kirstein described developments in Europe with special emphasis on
links to North America. He pointed out the problems managing shared
resource ``fat pipes'', multiplexed or not, where different links may
have quite different use restrictions or resource allocation policies
and thus, as an example, complex backup strategies. The problems here
can't be solved by just a technical or just an administrative group.
``Do we know how to manage bits of SPAN separated by bits of DARPA?''
Report on the Pacific - Torben Nielsen
Torben Nielsen mostly gave a status report on the Pacific. Korea is now
on. At some point New Zealand will be daisy-chained to Australia and
the direct link to Hawaii will be removed. Japan has multiple medium
speed links; working on merging them. Taiwan soon. Australia is no
longer urging Coloured Book protocols. Link to Europe within a year.
Singapore, Hong Kong, Indonesia are talking; Thailand and Malaysia are
interested.
Report on RFC work - Kent England
Progress is being made on the RFC for generic mid-level routing policy
and ``rules of thumb''. New guidelines presented at the meeting were:
explicitly engineer every fallback -- none should be accidental; avoid
routing ``ties'' -- there should be distinct preferences, to avoid
bistable situations; and the hardest problem to diagnose is oscillation.
The group working on the RFC continued that night.

Old and new issues of concern - Scott Brim
We had to skip this section because we were out of time. We are
continuing on the TEWG mail list.
Items that have been resolved since the last meeting:
o VMNET interaction with the Internet: VMNET is still being planned;
they will now be more conscious of the physical topology of the
Internet when designing their traffic flows.
o CSNet transcontinental link: Dan Long has written a routing plan
which demonstrates how they are being careful not to cause routing
problems with this link.
o CA*Net and its multiple connections to NSFNET (and NASA): Dennis
Ferguson has written a plan describing how they will use their
multiple connections.
Items that have been brought up outside the meeting so far are:
o The Army Supercomputer Network, and how it will interact with the
rest of the Internet.
o Paths which have both ends in the United States but
*unintentionally* travel through other countries. This same
problem exists for other countries as long as they have possible
fallback paths through other countries.
o NASA's ACTS satellite system and how it will interact with the
Internet.
Internet Cartography Project
Worked on jointly with the NJM working group, and presented in their
report.
