Presentation Transcript

  1. Seamoby – IETF 56 Pat Calhoun Airespace James Kempf DoCoMo Labs USA

  2. Agenda • Agenda discussion – chairs, 5 min. • Draft status – chairs, 10 min. • Open issues in CT design - John Loughney, 10 min. • Discussion, 20 min. • Open issues in CARD design - Ajoy Singh, 10 min. • Issues with server-based design - Dirk Trossin, 10 min. • Discussion - 20 min. • Moving forward, chairs - 10 min. • Discussion – 25 min.

  3. Draft Status • draft-ietf-seamoby-mobility-terminology-02.txt • Submit to IESG for publication as Informational after this meeting. • draft-ietf-seamoby-context-transfer-problem-stat.txt • Published 9/2002. RFC 3374. • draft-ietf-seamoby-cardiscovery-issues-04.txt • AD Evaluation 11/25/2002. No comments. • draft-ietf-seamoby-ct-reqs-05.txt • AD Evaluation 1/31/2003. No comments. • draft-ietf-seamoby-car-requirements-02.txt • Revised ID Needed 12/06/2002. Allison’s comments: Reviewed it carefully and it does not align well with the security comments from SMB and the complexity and architecture issues review that I gave in the 9/26 email to the mailing list.  As the state says, a revision is needed, even though the protocol is under development. • draft-ietf-seamoby-card-protocol-01.txt,draft-ietf-seamoby-ctp-01.txt • Under development by WG, to discuss today.

  4. Moving Forward

  5. CARD Architecture Learning based approach? Server based Approach? The Back End The Front End ICMP

  6. Reorganization • Freshness date is passed! • Going on 3 years since BOF, not much accomplished. • Reorganize, complete work that can be done within 6 months.

  7. CARD Reorganization Suggestion • Use requirements draft as guidelines, drop publication. • Requirements aren’t helpful to guide research, research questions are. • Framework for research on both server-based and learning-based approaches. • And possibly others. • Focus on IPv6. • Submit protocol to IESG for publication as Experimental after Vienna.

  8. Proposal for Experimental Draft • Complete CARD Front End in Seamoby. • Integrate FMIP and CARD signaling. • One Host to Router IETF protocol for CARD. • Inter-router protocol Back End supporting both server based and learning based approachs. • Later, if deployment interest, restart in INT Area for Proposed Standard.

  9. Research • Simulations to compare server-based and learning-based approaches. • Develop design approaches to solve AP auth/authz problem. • Utilize framework protocol to implement different approaches. • Join with new Mobile IP IRTF Research Group. • Return to IETF when problem better understood.

  10. Context Transfer Interest? • Decline in interest. • No response on list to chairs’ extensive review of DT CT draft. • Minor progress on draft since last IETF. • Competition from IAPP for 802.11 reduces market interest. • Is anybody interested in this work?

  11. If Not… • Let’s drop it.

  12. If So… • Use requirements draft as guidelines, drop publication. • Requirements aren’t helpful for guiding research, research questions are. • Focus on IPv6. • Complete protocol by Vienna. • Submit to IESG for publication as Experimental after Vienna.
