  1. UNI Extensions for Diversityand Latency Support • draft-fedyk-ccamp-uni-extensions-03 IETF 88 – CCAMP WG Don FedykDon.Fedyk@hp.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 Xihua Fu Fu.Xihua@zte.com.cn IETF 88 Vancouver

  2. Agenda • Updates from 02 to 03 version • New: multi-domain aspects • Single and multi-domain use cases • Next steps IETF 88 Vancouver

  3. Updates from 02 to 03 version • Diversity part for dual-homed CEs: • Section on multi-domain aspects added: • Subdividing identifier space • Scoping ID space to domains utilizing the domain sub-objectdefined in draft-ietf-ccamp-rsvp-te-domain-subobjects-00 • Latency part: • No updates • Draft fairly stable IETF 88 Vancouver

  4. Single domain diversity use case(SRLG example) 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 88 Vancouver

  5. Multi-domain diversity use case(sharing a single SRLG ID space) Shared SRLG ID Space Disjoint SRLR ranges for domains A, B, C, and D SRLG ID Range B SRLG ID Range D Domain B SRLG ID Range A PE Domain D PE Domain A PE SRLG_IDs(LSP1) PE PE PE CE CE PE PE Domain C PE PE PE PE SRLG_IDs(LSP2) SRLG ID Range C IETF 88 Vancouver

  6. Multi-domain diversity use case(Scoping the SRLG ID space to domains) SRLG IDs scoped by pre-pended domain ID subobject in RSVP message: SRLG_IDs(LSP1)= [domain_sub-object(DA), SRLG_IDs(DA)], [DB], [DC] Domain C sub-object Domain D sub-object Domain B Domain A sub-object PE Domain D PE Domain A PE SRLG_IDs(LSP1) PE PE PE CE CE Domain C PE PE PE PE PE PE SRLG_IDs(LSP2) Domain C sub-object IETF 88 Vancouver

  7. Next Steps • Solicit feedback/comments from the group • Further completion/refinement  multi-domain part • Collaboration with authors working on other GMPLS UNI/overlay model related drafts discussed in this CCAMP session • Ready for WG adoption IETF 88 Vancouver

  8. Thank You! IETF 88 Vancouver
