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.
