Abstract:

   Segment Routing (SR) enables a node to steer packet flows along a
   specified path without the need for intermediate per-path states, due
   to the utilization of source routing.  An SR Policy comprises a
   sequence of segments, which are essentially instructions that define
   a source-routed policy

   This document specifies a set of extensions to the Path Computation
   Element Communication Protocol (PCEP) for Segment Routing Policies
   that are designed to satisfy requirements for connection-oriented
   transport services (Circuit-Style SR policies).  They include the
   ability to control path recomputation and the option to request path
   with strict hops only and are also applicable for generic SR policy
   use cases where controlling path recomputation or deterministic and
   persistent path requirements are applicable.
