  1. GMPLS Extensions for MLN/MRN draft-rao-ccamp-mlnmrn-otn-ospfte-ext-03Rajan Rao & Khuzema Pithewan draft-zhang-ccamp-gmpls-h-lsp-mln-05Fatai Zhang, Xian Zhang, O. Gonzalez de Dios & C. Margaria CCAMP IETF-89, London

  2. Context & Problem Statement • Multiple switching capabilities exist in server Layer • Switching Cap, Adaptation & Switching Granularity • Above info is required for E2E TE path computations • Signaling also needs to carry server layer info • Existing RFCs do not cover all aspects of multi-layer . For e.g. OTN mux layer identification

  3. Example Advertises ISCD_PSC, IACD1 10GigE 100GigE Hybrid Node Ethernet Switch 300G Advertises ISCD_PSC, IACD2 OTU4 OTU4 OTN Switch Advertises ISCD_OTN, IACD1 IACD2 Advertises ISCD_OTN, IACD1 IACD2 IACD1 Upper SwitchCap/EncTyp : PSC/Ethernet Lower SwitchCap/EncType : OTN-TDM/G.709 ODUk SCSI : SignalType+HierarchyODU2-ODU4 (For 10GigE) IACD2 Upper SwitchCap/EncTyp : PSC/Ethernet Lower SwitchCap/EncType : OTN-TDM/G.709 ODUk SCSI : SignalType+HierarchyODU4(For 100GigE)

  4. Relevant Drafts – MLN/MRN I-Ds for Routing and Signaling extensions: • OSPF-TE extensions are addressed in • draft-rao-ccamp-mlnmrn-otn-ospfte-ext-03.txt • RSVP-TE extensions are addressed in • draft-zhang-ccamp-gmpls-h-lsp-mln-05.txt

  5. Status: draft-rao-ccamp-mlnmrn-otn-ospfte-ext-03 • No change since last IETF-88 • Draft is generic & Covers all layers • OTN & Ethernet • OTN & FlexGrid • OTN & SONET/SDH • OTN & OTN

  6. Status: draft-zhang-ccamp-gmpls-h-lsp-mln-05 • No change since last IETF-88 • Draft is generic & Covers all layers • TDM & packet(e.g, OTN (or SDH) & Ethernet (or MPLS-TP)) • TDM & wavelength (e.g, OTN & WSON) • TDM internal multilayer (e.g., OTN, SDH, OTN &SDH)

  7. Next Steps • We would like move both drafts together • We request for WG adoption
