  1. PCC-PCE Communication Requirements for Inter-Layer Traffic Engineering draft-ietf-pce-inter-layer-req-02.txt July 13, 2006 Eiji Oki (NTT) Jean-Louis Le Roux (France Telecom) Kenji Kumaki (KDDI) Adrian Farrel (Old Dog Consulting)

  2. Updates from 01 • Section 5.1.2:Control of The Type of Path to be Computed • Definition of a mono-layer path is modified. • a mono-layer path that is specified by strict hops but includes virtual TE link(s), or includes loose hop(s) . • Some rewordings for the sake of clarity

  3. List of PCC-PCE protocol requirement for inter-layer TE • PCC-PCE communication (inter-layer specific) • Indicate inter-layer path computation • Single-layer or inter-layer path computation • Indicate control of type of path route • Mono-layer or multi-layer path • Triggering nested signaling • Communication of inter-layer constraints • e.g. switching type and encoding type • Cooperation between single-layer PCEs • Inter-layer Diverse Paths

  4. Next step… • Propose to start work on inter-layer protocol extensions for PCEP • Probably new TLVs for existing objects • Requests for feedback.
