The document specifies an efficient mechanism to detect data plane
failures in MPLS data plane failures, i.e. failures of an LSPs.
The specification consists of two parts:
- information carried in an MPLS "echo request" and "echo reply"
for the purposes of fault detection and isolation
- mechanisms for reliably sending the echo reply messages.
Working Group Summary
This has been a major work performed by a dedicated to team and
the work has regularly been reported in f2f meetings and on the
working group mailing list.
There is a wide spread recognition that there is a need to
consolidate the LSP Ping specification (a widely deployed
technology) into a smaller number of documents.
The support for publishing this document is solid.
RFC 4379 is one of the most widely implemented and deployed MPLS
specifications, the documents that are being obsoleted are also
widely implemented and well deployed.
No specific reviews, other than what has been done within the
working group, are necessary.
