Ballot Text

Technical Summary

   The Path Computation Element Communication Protocol (PCEP) provides
   mechanisms for Path Computation Elements (PCEs) to perform path
   computations in response to Path Computation Clients (PCCs) requests.
   Segment Routing (SR) can be used to steer packets through a network
   employing the source routing paradigm.  SR can be applied to both
   MPLS (SR-MPLS) and IPv6 (SRv6) data planes.  Stateful PCEP extensions
   for SR allow a PCE to maintain state and to control and initiate SR
   Traffic Engineering (TE) LSPs.

   PCEP supports grouping of two unidirectional MPLS-TE Label Switched
   Paths (LSPs), signaled via RSVP-TE, using association.  This document
   defines PCEP extensions for grouping two unidirectional SR LSPs (one
   in each direction in the network) into a single associated
   bidirectional SR LSP.  The mechanisms defined in this document are
   applicable to both stateless and stateful PCEs for PCE-initiated and
   PCC-initiated LSPs.

Working Group Summary

   There was broad consensus in the working group on this work. This
   work builds on prior specifications published by the WG and extends
   them for segment routing. There was no controvery or contention with
   respect to this work. 

Document Quality

   There are at least two known/declared shipping commercial
   implementations of this specification. This specification
   extends previously published specification for use with
   segment routing and as such has gone through good reviews
   with the WG. It has gone through RTGDIR and OPSDIR early
   reviews and no other review was sought as it does not
   include any YANG, media type, or such contents.

Personnel

   The Document Shepherd for this document is Dhruv Dhody. The Responsible
   Area Director is Ketan Talaulikar.
