Hi PCE WG,

This update mainly includes:

* editorial modifications of some text, and references.
* changed some 'SHOULD' to 'MUST' according to the context, e.g. the PCE with highest priority MUST be response instead of SHOULD be response.
* added more detailed text in manageability considerations sub-section.

Comments are welcome. IMHO, this draft may be ready for WGLC already 😊

Thanks,
Cheng

Internet-Draft draft-ietf-pce-state-sync-06.txt is now available. It is a work item of the Path Computation Element (PCE) WG of the IETF.

   Title:   Inter Stateful Path Computation Element (PCE) Communication Procedures.
   Authors: Stephane Litkowski

Abstract:

   The Path Computation Element (PCE) Communication Protocol (PCEP)
   provides mechanisms for PCEs to perform path computation in response
   to a Path Computation Client (PCC) request.  The Stateful PCE
   extensions allow stateful control of Multi-Protocol Label Switching
   (MPLS) Traffic Engineering (TE) Label Switched Paths (LSPs) using
   PCEP.

   A Path Computation Client (PCC) can synchronize an LSP state
   information to a Stateful Path Computation Element (PCE).  A PCC can
   have multiple PCEP sessions towards multiple PCEs.  There are some
   use cases, where an inter-PCE stateful communication can bring
   additional resiliency in the design, for instance when some PCC-PCE
   session fails.

   This document describes the procedures to allow a stateful
   communication between PCEs for various use-cases and also the
   procedures to prevent computations loops.
