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.
