Technical Summary

   A Stateful Path Computation Element (PCE) maintains information on
   the current network state, including computed Label Switched Path
   (LSPs), reserved resources within the network, and the pending path
   computation requests.  This information may then be considered when
   computing new traffic-engineered LSPs, and for any associated and
   dependent LSPs, received from a Path Computation Client (PCC).

   RFC 7470 defines a facility to carry vendor-specific information in
   stateless PCE Communication Protocol (PCEP) messages.

   This document extends this capability for the Stateful PCEP messages.

Working Group Summary

The document reached a broad agreement for publication. Nothing significant to report.

Document Quality

There is an implementation by one vendor at least, as listed in Section 6.
