RSVP-TE extensions for MPLS-TP OAM Configuration

OAM Function field
  • draft-ietf-ccamp-oam-configuration-fwk
  • In case of MPLS-TP OAM
  • OAM Type 2
  • BFD is the Choosen tools for MPLS-TP CCCV in
    MPLS-TP

OAM Function
Continuity Check (BFD for CC)
Performance Monitoring/Loss
Performance Monitoring/Delay
Connectivity Verification (BFD for CCCV)

BFD for CCCV in G-ACh
  • 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

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
