Objectives

• Define failure detection and notification
  procedures between Ethernet PWs and associated
  native Ethernet ACs
• Defect State mapping between Ethernet PWs and
  associated Ethernet ACs
• OAM message mapping between various Ethernet OAM
  mechanisms (e.g., 802.1ag) and PW OAM mechanisms
  (e.g., BFD)
• Extensions to draft-ietf-pwe3-oam-msp-map-06.txt
  , "Pseudo Wire (PW) OAM Message Mapping",
  focusing on Ethernet PW services
• Use same terminology and reference model for
  defect state mapping

History

• draft-mohan-pwe3-mpls-eth-oam-iwk-00.txt was
  submitted in November 2007, and presented in IETF
  71 (March 2008) in Philadelphia
• draft-mohan-pwe3-mpls-eth-oam-iwk-01.txt, current
  draft, addresses the comments received in the
  Philadelphia meeting and on the mailing list
  after that
• PWE3 WG decision in Dublin was to re-confirm
  progressing the draft as a WG draft

4
Main Changes From Previous version 00 to 01

• Ali Sajassi (Cisco) joined as a co-editor
• Addressed comments from the Philadelphia meeting
  and mailing list
• Called out 802.3ah link OAM and Loss of Signal
  (LoS) for link failure detection and notification
  
• Added E-LMI support

5
Next Steps

• Publish draft-mohan-pwe3-mpls-ethe-oam-iwk-01.txt
  as a WG document per Dublin outcome
• Will be done immediately after the Minneapolis
  Meeting
• Solicit additional input/comments from the WG
• Some comments were related to defining a
  mandatory subset of the interworking mechanisms
  more feedback and discussion are needed
