2 November 2009 IETF 76, Hiroshima draft-ietf-ccamp-oam-configuration-fwk 1000000000000000 OAM Function 0100000000000000 1010000000000000 0001000000000000 0000111111111111 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

3 November 2009 IETF 76, Hiroshima BFD for CC: TLV Definition Path/Resv message LSP Attributes OAM Configuration TLV BFD CC Configuration TLV

4 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

5 November 2009 IETF 76, Hiroshima BFD for CC&CV: TLV Definition Path/Resv message LSP Attributes OAM Configuration TLV BFD CC&CV Configuration TLV

6 November 2009 IETF 76, Hiroshima BFD CC&CV OAM Configuration TLV LSP (RSVP-TE) PE PP Section BFD session draft-bellagamba-ccamp-rsvp-te-mpls-tp-oam-ext Unique MEP-ID of source BFD control packet encapsulated in the ACH Unique MEP-ID of source BFD control pkt BFD control packet encapsulated in the ACH Unique MEP-ID of source BFD control pkt Example of GMLS setup of BFD for CC&CV

7 November 2009 IETF 76, Hiroshima Next Steps Work in collaboration with the authors of: –draft-ietf-ccamp-oam-configuration-fwk –draft-ietf-ccamp-rsvp-te-eth-oam-ext –draft-kern-ccamp-rsvp-te-sdh-otn-oam-ext-01 Integrate the remaining MPLS-TP OAM tools Adopt it as CCAMP WG document
