Technical Summary

 This document extends the procedures and Connectivity Verification (CV) types
already defined for Bidirectional Forwarding Detection (BFD) for Virtual Circuit
Connectivity Verification (VCCV) to define Seamless BFD (S-BFD) for VCCV. 
It updates RFC 5885, extending the CV Values and the Capability Selection, and
is thus being submitted to be a Proposed Standard.

Working Group Summary

The draft has been non-controversial and there were no objections to consensus at any point.
Document Quality

 The draft is externally cited by a CableLabs document, Data-Over-Cable
Service Interface Specifications DCA - MHAv2

as a MUST for portions of its functionality. To my knowledge it has not yet been
implemented, as it has not received IANA early allocations, but it is in at least
one vendor's roadmap once the allocations have been made.
