Presentation Transcript

  1. Update on Inter-layer • Framework • draft-ietf-pce-inter-layer-frwk-05.txt • Requirements • draft-ietf-pce-inter-layer-req-06.txt • Solutions: PCEP extensions • draft-oki-pce-inter-layer-ext-00.txt

  2. Framework for PCE-Based Inter-Layer MPLS and GMPLS Traffic Engineering draft-ietf-pce-inter-layer-frwk-05.txt December 4, 2007 Eiji Oki (NTT) Jean-Louis Le Roux (France Telecom) Adrian Farrel (Old Dog Consulting)

  3. Context • Multi-layer networks (MLN) • Often administered with limited TE visibility • Specifically mentioned in the charter • Usage models • One PCE sees everything • One PCE per-layer • Relationship with NMS NMS VNT Mgr PCE All PCE Hi PCE Lo

  4. Document update • Changes from 04 • NMS-VNTM cooperation model added • Possible combinations of inter-layer path computation and inter-layer path control models added • This draft is now stable. • Next step • Requests for feedback.

  5. PCC-PCE Communication and PCE Discovery Requirements for Inter-Layer Traffic Engineeringdraft-ietf-pce-inter-layer-req-06.txt December 4, 2007 Eiji Oki (NTT) Jean-Louis Le Roux (France Telecom) Kenji Kumaki (KDDI) Adrian Farrel (Old Dog Consulting)

  6. Summary of Requirements • Supplements RFC 4657 and RFC 4674 • Only defines new requirements • PCC-PCE Communication • Control of Inter-Layer Path Computation • Control of type of path to compute • Mono-layer (all TE links in only one layer) • Strict or loose hops • Multi-layer path (TE links from different layers) • Hierarchy acceptable? • Triggered signaling allowed? • Inter-layer constraints • Switching type and adaptation • Capabilities Advertisements for PCE Discovery

  7. Document update • Changes from 05 • Only minor changes • Some rewordings for the sake of clarity in section 3.1.2. • This draft is now stable. • Next step • Requests for feedback.

  8. Extensions to the Path Computation Element communication Protocol (PCEP) for Inter-Layer MPLS and GMPLS Traffic Engineering draft-oki-pce-inter-layer-ext-00.txt December 7, 2006 Eiji Oki (NTT) Jean-Louis Le Roux (France Telecom) Adrian Farrel (Old Dog Consulting)

  9. Summary of solution draft • New draft. • PCEP extensions for inter-layer traffic engineering that satisfy the requirements described in draft-ietf-pce-inter-layer-req • Protocol Extensions • INTER-LAYER Object • SWITCH-LAYER Object • REQ-ADAP-CAP Object • Procedure

  10. Next step • Requests for feedback. • Adopt as a WG document?
