  1. UNI Extensions for Diversityand Latency Support • draft-fedyk-ccamp-uni-extensions-01 IETF 86 – CCAMP WG Don FedykDonald.Fedyk@alcatel-lucent.com Dieter Beller Dieter.Beller@alcatel-lucent.com LievenLevrauLieven.Levrau@alcatel-lucent.com Daniele CeccerelliDaniele.Ceccarelli@ericsson.com Fatai ZhangZhangFatai@huawei.com Yuji TochioTochio@jp.fujitsu.com IETF 86 Orlando

  2. Agenda • I-D history and brief overview • Updates from 00 to 01 version • Relationship with other CCAMP work • Next steps IETF 86 Orlando

  3. I-D History and Brief Overview • draft-fedyk-ccamp-l1vpn-extnd-overlay-01 becamedraft-fedyk-ccamp-uni-extensions-00 as per Vancouver meeting suggestion to broaden the applicability scope from GMPLS UNI for L1VPNs to the GMPLS UNI in general: • Title/I-D file name changed • Content aligned with new scope • Still applicable to the GMPLS UNI for a L1VPN following the overlay extension service model (L1VPN is a special case of the general UNI case) • draft-fedyk-ccamp-uni-extensions-00 is still addressing: • UNI extensions for achieving diversity in the provider network • UNI extensions to deal with latency/latency variation (delay/delay variation) constraints IETF 86 Orlando

  4. Updates from 00 to 01 version • Diversity part: • Error handling procedures added • Latency part: • “Latency Signaling Extensions” section revised (new text added) • Reference added and references updated IETF 86 Orlando

  5. Relationship with other CCAMP work • draft-fedyk-ccamp-uni-extensions-01 complements: • draft-ietf-ccamp-lsp-diversity-01.txt • draft-ali-ccamp-extended-srlg-00.txt • these drafts address signaling extensions to support LSP diversity and SRLG for multi-provider domain networks • draft-fedyk-ccamp-uni-extensions-01 differs from: • draft-beeram-ccamp-melg-00.txt • draft describes routing actions on a virtual topology that has been provided to the CEs IETF 86 Orlando

  6. Next Steps • Solicit feedback/comments from the group • Further refinement of dual-homing solution including more detailed signaling extensions • Further refinement of latency section • Collaboration with authors working on: draft-farrel-interconnected-te-info-exchange-00.txt IETF 86 Orlando

  7. Thank You! IETF 86 Orlando

  8. Backup Slides IETF 86 Orlando

  9. Dual-homing Problem Statement LSP1 PE1 P P PE CE CE LSP2 PE2 P P PE Problem Statement: ensure that LSP1 and LSP2 are mutually disjoint IETF 86 Orlando

  10. Option 1: Exchange of SRLG List LSP1 SRLG_IDs(LSP1) PE1 P P PE SRLG_IDs(LSP2) CE CE LSP2 PE2 P P PE SRLG_IDs(LSP1) Exchange of SRLG ID list for disjoint LSPs via source CE node IETF 86 Orlando

  11. Option 2: Exchange of Path Affinity Set LSP1 PAS(LSP1) PE1 P P PE CE CE LSP2 PE2 P P PE PAS(LSP1) • Exchange of PAS + LSP ID via source CE node • Dissemination of (PAS, LSP ID, SRLG IDs) among PEs for each L1VPN IETF 86 Orlando
