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.
This draft is part of a group of drafts for Seamless BFD (see the references for the related drafts). As some of these drafts are normative references, this draft will need to be published as a part of an RFC Editor cluster.
2. Review and Consensus
As IETF work items go, this draft progressed relatively quickly, as the initial individual draft came out only about a year ago. One of the reasons that it has progressed so rapidly is that the draft has received good discussion and review, first as an individual draft and then as a working group draft. It also received attention as being a part of the larger Seamless BFD effort. The acknowledgements section in the draft reflects the people that submitted substantive reviews and comments. Two WG LC reviews in particular resulted in some good improvements in the draft.
The draft has been non-controversial and there were no objections to consensus at any point.
The draft is externally cited by a CableLabs document, Data-Over-Cable Service Interface Specifications DCA - MHAv2 ( http://www.cablelabs.com/wp-content/uploads/specdocs/CM-SP-R-DEPI-I03-161021.pdf ) 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.
3. Intellectual Property
Each author has confirmed conformance with BCP 78/79. There are no IPR disclosures on the document.
4. Other Points
This draft does not create any new IANA registries. It requests allocations in existing registries that require IETF consensus/review, but not expert review. The allocation requests are clear and straightforward for IANA to execute.
