The IESG has approved the following document: - 'MPLS and Ethernet OAM Interworking' (draft-ietf-pwe3-mpls-eth-oam-iwk-08.txt) as Proposed Standard This document is the product of the Pseudowire Emulation Edge to Edge Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pwe3-mpls-eth-oam-iwk/ Technical Summary This document specifies the mapping of defect states between Ethernet Attachment Circuits (ACs) and associated Ethernet Pseudowires (PWs) connected in accordance to the PWE3 architecture to realize an end-to-end emulated Ethernet service. It standardizes the behavior of Provider Edges (PEs) with respect to Ethernet PW and AC defects. Working Group Summary Solutions for mapping OAM messages related to defect notifications from attachement circuits to PWs for ATM, FR, and TDM services were specified in RFC6310. This RFC did not cover Ethernet attachment circuits because of a perception at the time that Ethernet OAM mechanisms were less widely deployed and their standardization was on-going. The WG decided to handle the Ethernet case in a separate draft. This was considered to be an important work item by the PWE3 working group, and there were a number of requests to roll this working into the draft that became RFC6310. However, ultimately the consensus was to progress the Ethernet case separately to not further delay RFC6310. The document received two working group last calls, the second as a result of IPR declaration 1781. The second WG last call resulted in the security section being improved, but no issues were raised about the IPR declaration. Document Quality Previous PW deployment surveys (see draft-ietf-pwe3-pw-vccv-impl-survey-results-00) have indicated that the majority of PWs are Ethernet, and therefore standardizing the interworking of defect notifications for emulated Ethernet services is expected to be of significant interest to the IETF and the operator community in general. There are believed to be numerous implementations and deployments of Ethernet OAM mechanisms referred to in this draft, including cases where the Ethernet service is supported over PWs and where OAM interworking is used.
