The IESG has approved the following document: - 'Path Computation Element Communication Protocol (PCEP) Extensions for Signaling Multipath Information' (draft-ietf-pce-multipath-29.txt) as Proposed Standard
This document is the product of the Path Computation Element 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-pce-multipath/ Technical Summary A Segment Routing (SR) Policy Candidate Path can contain multiple Segment Lists, allowing for load-balancing and redundancy across diverse paths. However, current PCEP extensions for SR Policy only allow signaling of a single Segment List per Candidate Path. This document defines PCEP extensions to encode multiple Segment Lists within an SR Policy Candidate Path, enabling multipath capabilities such as weighted or equal-cost load-balancing across Segment Lists. These extensions are designed to be generic and reusable for future path types beyond SR Policy, and are applicable to both stateless and stateful PCEP. Working Group Summary This document was in development with the PCE WG for over 5 years and has received good reviews, feedback, and support for progression. Over the course of these years, there have been many contributors to this document that resulted in 9 authors. This was addressed late in the WG phase by identifying two editors on the front page and additional authors in a separate section. There was also one specific extension related to backup paths that was moved into a different WG document that actually used that extension to unblock the progression of this document to publication as RFC. Document Quality The document is of good quality and has benefited from reviews by a diverse set of WG participants that are also implementers. There are at least 3 implementations reported in the document with varying level of support for the extensions in this document. The document has received early directorate reviews from RTGDIR and OPSDIR. There is technology overlap with SPRING WG and this is covered by the overlap in WG participants and worked on and reviewed this document. No other specific external or expert review was thought to be necessary. Personnel The Document Shepherd for this document is Adrian Farrel. The Responsible Area Director is Ketan Talaulikar. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
