  2. MONDAY, March 17, 2003 - 0900-1130 • Agenda bashing - chair - 5 minutes • Interim Meeting review - chair - 15 minutes • RSVP discussion – Melinda Shore – 30 minutes • Problems to solve – Henning Schultzrinne - 30 minutes • NSIS Analysis doc - Jukka Manner - 15 minutes • http://www.ietf.org/internet-drafts/draft-ietf-nsis-signalling-analysis-01.txt • An Evaluation on RSVP Transport Mechanism - Ping Pan - 15 minutes • http://www.ietf.org/internet-drafts/draft-pan-nsis-rsvp-transport-01.txt

  3. Interim Meeting Update - Consensus • Seperate transport layer protocol state from NTLP state • Soft-state refresh supported independent of transport protocol state. • Extensibility should be provided (see something which a node does not understand, session should not fail) • Seperate flow identifier and session identifier. • Session identifier should be unique. • Don’t overload ids • Link-based congestion control is not a good thing. • Scoping of requests should be avoided (see IPv6 mailing list)

  4. Interim Meeting Update - Problematic Issues • Uniqueness of session id • Supporting multiple transport protocol options create complexity • Security properties & needs • Mobility support

  5. TUESDAY, March 18, 2003 - 1300-1400 • Agenda bashing - chair - 5 minutes • NSIS Requirements doc - Marcus Brunner - 15 minutes • http://www.ietf.org/internet-drafts/draft-ietf-nsis-req-07.txt • NSIS Framework document - Robert Hancock - 20 minutes • http://www.ietf.org/internet-drafts/draft-ietf-nsis-fw-02.txt • RSVP Security Properties - Hannes Tschofenig - 10 minutes • http://www.ietf.org/internet-drafts/draft-ietf-nsis-rsvp-sec-properties-01.txt • NSIS Security Threats - Hannes Tschofenig - 10 minutes • http://www.ietf.org/internet-drafts/draft-ietf-nsis-threats-01.txt

  6. Starting NTLP Work • Melinda Shore & Henning Schulzrinne to co-author; Bob Braden & Michael Thomas to act as expert reviewers. • Starting point • RSVP (2205 + 2961) • Separate service specific stuff out • Separate flow spec & session id • Keep semantics of PATH (discovery & transport combined) • Soft state • Support of RSVP-proxies • Open issues (testing consensus) • Logically separate discovery & transport, in practice they could be piggybacked. • Message fragmentation concerns • Reliability concerns • Optionally supporting other transport protocols • Reduction of multicast complexity • 2752 / policy issues • Routing interaction (handling mid-session path splitting) • Support for explicitly stating message directionality & hop-by-hop vs. end-to-end.
