  Path Computation Element communication Protocol (PCEP) extension for
          associating Policies and Label Switched Paths (LSPs)
                  draft-ietf-pce-association-policy-06

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).

1.  Introduction

   [RFC5440] describes the Path Computation Element communication
   Protocol (PCEP) which enables the communication between a Path
   Computation Client (PCC) and a Path Control Element (PCE), or between
   two PCEs based on the PCE architecture [RFC4655].  [RFC5394] provides
   additional details on policy within the PCE architecture and also
