The IESG has approved the following document: - 'Optimizing BFD Authentication' (draft-ietf-bfd-optimizing-authentication-36.txt) as Experimental RFC
This document is the product of the Bidirectional Forwarding Detection Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard and Ketan Talaulikar. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-bfd-optimizing-authentication/ 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. Personnel The Document Shepherd for this document is Reshad Rahman. The Responsible Area Director is Ketan Talaulikar.
