Abstract:

   Certain traffic engineering path computation problems require
   solutions that consist of multiple traffic paths that together form a
   solution.  Returning a single traffic path does not provide a valid
   solution.  This document defines mechanisms to encode multiple paths
   for a single set of objectives and constraints.  This allows encoding
   of multiple Segment Lists per Candidate Path within a Segment Routing
   Policy.  The new Path Computation Element Communication Protocol
   (PCEP) mechanisms are designed to be generic, where possible, to
   allow for future re-use outside of SR Policy.  The new PCEP
   mechanisms are applicable to both stateless and stateful PCEP.
   Additionally, this document updates RFC 8231 to allow encoding of
   multiple Segment Lists in PCEP.
