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

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.
