 Path Computation Element (PCE) Communication Protocol (PCEP) extension
        for associating Policies and Label Switched Paths (LSPs)
                  draft-ietf-pce-association-policy-16

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).  The
   extension allows a PCEP speaker to advertise to a PCEP peer that a
   particular LSP belongs to a particular Policy Association Group.
