Hi all,
A new version of the PCE-based inter-layer framework draft has
been published:
http://www.ietf.org/internet-drafts/draft-ietf-pce-inter-layer-frwk-02.txt
Main changes are:
- In section 4.3, we added the case that the higher layer is multi-homed.
- In section 6.4, we added the section of network complexity.
- References were updated.
Any comments and suggestions are highly appreciated.
Thank you.
Eiji

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Path Computation Element Working Group of the
IETF.
Title : Framework for PCE-Based Inter-Layer MPLS and GMPLS
Traffic Engineering
Author(s) : E. Oki, et al.
Filename : draft-ietf-pce-inter-layer-frwk-02.txt

A network may comprise of multiple layers. It is important to
globally optimize network resources utilization, taking into
account all layers, rather than optimizing resource utilization at
each layer independently. This allows better network efficiency to
be achieved through a process that we call inter-layer traffic
engineering. The Path Computation Element (PCE) can be a powerful
tool to achieve inter-layer traffic engineering.
This document describes a framework for applying the PCE-based path
computation architecture to inter-layer MPLS and GMPLS traffic
engineering. It provides suggestions for the deployment of PCE in
support of multi-layer networks. This document also describes
network models where PCE performs inter-layer traffic engineering,
and the relationship between PCE and a functional component called
the Virtual Network Topology Manager (VNTM).

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.
