Internet-Draft draft-ietf-pce-multipath-21.txt is now available. It is a wo=

item of the Path Computation Element (PCE) WG of the IETF.

   Title:   Path Computation Element Communication Protocol (PCEP) Extensio=
ns for Signaling Multipath Information
   Authors: Mike Koldychev
            Samuel Sidor
   Name:    draft-ietf-pce-multipath-21.txt
   Pages:   32

Abstract:

   A Segment Routing (SR) Policy Candidate Path can contain multiple
   Segment Lists, allowing for load-balancing and protection 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.
   The extensions are designed to be generic and reusable for future
   path types beyond SR Policy, and are applicable to both stateless and
   stateful PCEP.
