Technical Summary
This document describes an experimental optimization to BFD
Authentication. It provides procedure where BFD state transitions
require strong authentication and permits the majority of BFD Control
Packets to use a less computationally intensive authentication
mechanism. This enables BFD to scale better when there is a desire
to use strong authentication.
Working Group Summary
The WG consensus represents the strong consensus of a few
individuals. The document got WG attention during the initial
phase of progression through the WG and at one point the
proposal in the document did change significantly (i.e., use
of the ISAAC mechanism covered in the companion document
draft-ietf-bfd-secure-sequence-numbers). During the later
phases in the WG, the document did not receive significant
further inputs/reviews due to lack of active implementation
interest. Thereafter, it was picked up for WGLC where it
received some further reviews and support for publication as
part of the set of 3 related documents that extend BFD
authentication.
There was opposition from one WG member over the licensing
term of the IPR that was declared. Besides that, there were
no controversies or threat of appeals.
Document Quality
There are no known implementations or plans for implementation.
The work started as Proposed Standard and then was the track
was changed by the WG to Experimental as the WG believes
implementation experience was required to ensure maturity as
a Proposed Standard.
The document has undergone review from YANG doctors, as well
as early directorate reviews from RTG, SEC and OPS areas.
