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.
