Hi all, Here are the major changes in this new revision of the IGP-based PCE discovery ID:
-Clarified the definition and applicability of PCE preferences (in the PATH-SCOPE TLV). -Added protocol elements and procedures for discovery of PCE Congestion Status. A new TLV is defined, the PCES (PCE Status) TLV to be carried within the ISIS Cap TLV and OSPF RI LSA. It allows advertising when a PCE enters or leaves a processing congestion state. Procedures to avoid any impact on the IGP scalability (dampening, hysterisis, congestion duration) are discussed. -Some rewordings for the sake of clarity -Added a new co-author Your comments on this new revision are required.
