The IESG has received a request from the Path Computation Element WG (pce) to
consider the following document: - 'Path Computation Element Communication
Protocol (PCEP) Extensions for
   Signaling Multipath Information'
  <draft-ietf-pce-multipath-25.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2026-06-03. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   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.
