OLD
Path Communication Element (PCE) communication Protocol (PCEP) extension
for associating Policies and Label Switched Paths (LSPs)

Path Communication Element (PCE) Communication Protocol (PCEP) extension
for associating Policies and Label Switched Paths (LSPs)
1. Introduction
OLD
[RFC5440] describes the Path Computation Element communication
Protocol(PCEP) which enables communication between a Path Computation
Client(PCC) and a Path Control Element (PCE),
NEW
[RFC5440] describes the Path Computation Element Communication
Protocol(PCEP) which enables communication between a Path Computation
Client(PCC) and a Path Computation Element (PCE),
2. Terminology
OLD
PCC: Path Computation Client. Any client application requesting a path
computation to be performed by a Path Computation Element.
NEW
PCC: Path Computation Client; any client application requesting a
path computation to be performed by a Path Computation Element.
OLD
PCE: Path Computation Element. An entity (component, application,
or network node) that is capable of computing a network path or
route based on a network graph and applying computational
constraints.
NEW
PCE: Path Computation Element; an entity (component, application, or
network node) that is capable of computing a network path or route
based on a network graph and applying computational constraints.
3. Motivation
OLD
Similarly, a PCC could request a user- or service-specific policy
NEW
Similarly, a PCC could request a user-specific or service-specific policy
3.1 Policy based Constraints
OLD
In the context of policy-enabled path computation [RFC5394], path
computation policies may be applied at both a PCC and a PCE.
NEW
In the context of Policy-Enabled Path Computation Framework [RFC5394], path
computation policies may be applied at either a PCC or a PCE or both.
OLD
The PCC may also apply user- or service-specific policies to decide
NEW
The PCC may also apply user-specific or service-specific policies to decide
OLD
The user- or service-specific policies applied to PCC and are passed to the
PCE along with the Path computation request, in the form of constraints
[RFC5394]
NEW
The user-specific or service-specific policies applied to PCC are passed to
the PCE along with the path computation request, in the form of constraints
[RFC5394]
4. Overview
OLD
This document defines a new Association type, called “Policy Association”
(TBD1), based on the generic ASSOCIATION object.
NEW
This document defines a new association type, called “Policy Association”
of value 3, based on the generic ASSOCIATION object.
OLD
This capability exchange for the PAT (TBD1) MUST be done before using the
policy association.
NEW
This capability exchange for the PAT MUST be done before using the policy
association.
OLD
Thus the PCEP speaker MUST include the PAT (TBD1) in the ASSOC-Type-List TLV
NEW
Thus the PCEP speaker MUST include the PAT in the ASSOC-Type-List TLV
