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
   Circuit Style Policies'
  <draft-ietf-pce-circuit-style-pcep-extensions-13.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 2026-02-20. 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


   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 can consist of
   one or a set of candidate paths, where each candidate path is
   represented by a segment list or a set of segment lists, which are
   essentially instructions that define a source-routed path.

   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 modification and the option to request a
   strict hop-by-hop path, being also applicable for generic SR policy
   use cases where controlling path modification or deterministic and
   persistent path requirements are applicable.
