Title : PCC-PCE Communication and PCE Discovery Requirements for Inter-Layer Traffic Engineering
Author(s) : E. Oki
Filename : draft-ietf-pce-inter-layer-req-05.txt
Pages : 12
Date : 2007-7-10
The Path Computation Element (PCE) provides functions of path
computation in support of traffic engineering in Multi-Protocol
Label Switching (MPLS) and Generalized MPLS (GMPLS) networks.
MPLS and GMPLS networks may be constructed from layered
client/servicr networks. It is advantageous for overall network
efficiency to provide end-to-end traffic engineering across multiple
network layers. PCE is a candidate solution for such requirements.
Generic requirements for a communication protocol between Path
Computation Clients (PCCs) and PCEs are presented in "PCE
Communication Protocol Generic Requirements". Generic requirements
for PCE discovery protocol are presented in "Requirements for Path
Computation Element (PCE) Discovery".

In the body type:
"FILE /internet-drafts/draft-ietf-pce-inter-layer-req-05.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
