69th IETF, Chicago, July 2007 Working Group Update New RFC: RFC 4927 on Path Computation Element Communication Protocol (PCECP) Specific Requirements for Inter-Area MPLS and GMPLS Traffic Engineering We need to now close on draft-ietf-pce-interas-pcecp-reqs Rev -02 just posted Please review and comment Objective is to LC after Chicago PCEP (rev08: editorial + minor enhancement) 9 Implementations ! BRPC quite stable (refresh until LC) New Working Group IDs: draft-ietf-pce-global-concurrent-optimization-00 MIB work on PCEP makes progress

69th IETF, Chicago, July 2007 Working Group Update IS-IS and OSPF PCE Discovery IDs Comments received during IESG review New revisions (-06) just posted Terminology: PCE Congested -> PCE Overloaded Congestion Duration field removed from the CONGESTION sub-TLV (now called OVERLOAD sub-TLV). Clarification on the usage of the “overload” information PCE address MUST be reachable => SHOULD "An IS-IS/OSPF implementation SHOULD..." replaced by "A PCE implementation supporting the IS-IS/OSPF extensions SHOULD" On-going discussion on whether to use the RI LSA or define a new Opaque LSA New PCE/OSPF/ISIS WG LC right after Chicago once we will have cleared the DISCUSS.
