     Path Computation Element communication Protocol extension for
                     associating Policies and LSPs
                  draft-ietf-pce-association-policy-01

Abstract

   This document introduces a simple mechanism to associate policies to
   a group of Label Switched Paths (LSPs) via an extension to the Path
   Computation Element (PCE) Communication Protocol (PCEP).
