November 2009 IETF 76, Hiroshima draft-ietf-ccamp-oam-configuration-fwk OAM Function Continuity Check (BFD for CC) Performance Monitoring/Loss Performance Monitoring/Delay Connectivity Verification (BFD for CC&CV) To be Defined OAM Function field In case of MPLS-TP OAM: OAM Type = 2 BFD is the Choosen tools for MPLS-TP CC&CV in MPLS-TP

November 2009 IETF 76, Hiroshima Unique MEP-ID of source of the BFD packet provides a global context for the BFD session so if packet is mis-delivered, lost context can not be confused Based on draft-asm-mpls-tp-bfd-cc-cv The new tool is obtained introducing Unique MEP-ID, between the ACH (Associated Channel Header) and the current BFD The benefit of this solution is to maintain the base behavior and protocol version of BFD Unique MEP-ID of source of BFD packet BFD Control Packet …from draft-swallow-mpls-tp-identifiers Unique MEP-ID ME ID Node ID Logical Interface Handle BFD for CC&CV in G-ACh
