  1. Applicability analysis of Generalized Multiprotocol Label Switching (GMPLS) protocols for the Layer 1 Virtual Private Network (L1VPN) Enhanced Mode draft-takeda-l1vpn-applicability-enhanced-mode-00.txt Deborah Brungard (AT&T) Adrian Farrel (Old Dog Consulting) Hamid Ould-Brahim (Nortel Networks) Dimitri Papadimitriou (Alcatel) Tomonori Takeda (NTT) 67th IETF San Diego November 2006

  2. History • draft-ietf-l1vpn-applicability-01 • Applicability analysis (gap analysis) covering both of the basic mode and the enhanced mode • Agreed to split into the basic mode part and the enhanced mode part in the IETF65 • The intent is to complete the basic mode part immediately following the basic mode solution work • This I-D is the enhanced mode part • The document is still gap analysis 67th IETF San Diego November 2006

  3. Document Scope • Analyze how GMPLS is applicable to the L1VPN Enhanced Mode • Identify areas for protocol enhancement • The point is how to realize CE-PE routing • Basically, basic mode signaling is equally applicable to the enhanced mode • Convert to an applicability statement as solutions are completed • The text is mostly cut-and-paste from the original version (with text clean-up) 67th IETF San Diego November 2006

  4. Enhanced Mode Sub Models Physical topology P C C CE PE PE CE P Customer site A (VPN#1) Customer site B (VPN#1) Provider network (GMPLS transport network) Overlay extension Virtual Node C C Virtual node CE CE CE CE Virtual Link Per VPN Peer Virtual link P C C C C CE CE PE PE CE CE PE PE P TE information or reachability only 67th IETF San Diego November 2006

  5. Summary of Applicability Analysis 1/2 67th IETF San Diego November 2006

  6. Summary of Applicability Analysis 2/2 67th IETF San Diego November 2006

  7. Next Steps • Ready for WG document? • This I-D is about how easy to support each sub model. In addition, maybe helpful to look at how useful each sub model is. • Look at draft-li-l1vpn-enhanced-mode-analysis • Is there any other sub model? • Look at draft-yasukawa-pce-vpn-req • Select one or two sub model(s) that the WG is going to focus on for solution work 67th IETF San Diego November 2006
