  3. Agenda • 05 mins: Admistrativa • 25 mins: Report from the Interim Meeting • 30 mins: Mesh • 30 mins: Hubs and Spokes • 10 mins: Fred Templin IP tunneling and MTU • 10 mins: General documents the working group needs to take on • 10 mins: Next Steps and Phase 2

  4. Interim Meeting Summary.1 • NOTES: http://bgp.nu/~dward/softwires/2006-02SoftwiresInterimNotes.html • Reviewed some current deployments • KDDI, Freenet6 • Reviewed Security Analysis • Criteria for selection was evaluated based on MUSTs from Problem Statement • ATS6, TSP, 2@L2TPv2, L2TPv3 were proposed as solutions for Hub & Spoke • V4overV6 and tunnel saf were proposed as solutions for Mesh

  5. Interim Meeting Conclusions.1 • Attendees reached consensus on solutions for both scenarios • L2TPv2 was selected as Phase 1 solution for H&S • L2TPv3 was selected as Phase 2 solution for H&S • Combined MPBGP solutions from Yong Cui and C. Metz was selected for Mesh solution • Attendees reached conclusion on next steps • Phase 1 Framework solution for H&S to be written immediately How to solve H&S scenarios w/ L2TPv2 • Phase 2 Framework solution for H&S to be presented as soon as Phase 1 is documented How to solve all H&S requirements w/ L2TPv3 and propose extensions • Create Framework doc for solutions to Mesh scenario How to solve all Mesh requirements w/ MPBGP and propose extensions Adopt Multicast solution by Shepherd, Wu, Li, Farinacci as WG doc • Adopt security analysis and radius extensions as WG docs

  6. Interim Meeting Conclusions.2 • Meeting continued second day w/ break out sessions on two scenarios • Proposed third interim meeting in “September” • Discuss Framework for Phase 2 H&S • List extension set for Phase 2 • Finalize extension set for Mesh • Meeting in Hong Kong was very successful • Many thanks to hosts: CERNET and CHUK • Many thanks to Mark Townsley (INT AD) for being present and keeping us to present and future process • Rough consensus was achieved and notes posted to list

  7. WG activities since the interim meeting • The chairs posted on March 3rd a message with the title: "Notes and Consensus from Interim Meeting in Hong Kong". A number of clarification questions were asked on the mailing list since. • Problem Statement draft at -01. Needs final, final edits in -02 (any second now) • Softwire ML statistics since the interim meeting: • 26 From: Jordi Palet Martinez • 15 From: Alain Durand • 12 From: Maria A. Dos Santos • 11 From: David Ward • 8 From: JF Tremblay • 7 From: Michael Fiumano • 5 From: Bill Storer • 3 From: Tim Chown • 2 From: Ole Troan • 1 From: HUI-HCHBJ DENG • 1 From: Eric Gray • 1 From: Laurent Toutain • 1 From: Tschofenig, Hannes • 1 From: Bruno STEVANT • 1 From: Marc Blanchet • 1 From: Pekka Savola • Much interesting discussion on TTM, support, deployment and technical criteria • No Open issues remain

  8. Consensus • Given that: • There was discussion involving many wg participants • No open issues considered remaining • Solution providers will represent a common vision in next presentations as stated in interim meeting notes and conclusion • We declare rough working group consensus: • Hub & Spokes scenario: • L2TPv2 chosen as the immediate solution • L2TPv3 in phase 2 as a backward compatible upgrade • Mesh scenario: • Conjoined effort for extensions to MPBGP based on work presented by Chris Metz and Yong Cui

  9. Presentations • Mesh • H&S • Fred • Next steps

  10. Deliverables • General docs • Security analysis • Radius accounting • Mesh • Framework doc using MPBGP • Multicast draft extensions • tunnel-safi and any additional softwires attributes • To be reviewd by L2VPN, L3VPN, IDR, Security types • Hub and Spoke • Phase 1 Framework doc using L2TPv2 • Phase 2 Framework doc using L2TPv3Extensions

  11. Next Deliveries • July 2006 • Security analysis • Radius accounting • Mesh Framework doc using MPBGP • Mesh Multicast draft extensions • Mesh tunnel-safi and any additional softwires attributes • Hub and Spoke Phase 1 Framework doc using L2TPv2 • Potential Interim WG meeting September 2006 • Focus on Hub and Spoke Phase 2 and Mesh extensions • November 2006 • Hub and Spoke Phase 2 Framework doc using L2TPv3 • Any new Mesh extensions • March 2007 • Hub and Spoke Phase 2 Extensions
