[Pce] [Fwd: I-D ACTION:draft-oki-pce-inter-layer-app-00.txt]

folks,

i'm not necessarily sure to understand the scenario 5.2 wrt to section 4.2

are you saying that in order to manage inter-layer relationship there is 
a need to have a separate functional entity (in addition to the PCE) ?

i'm a bit confused here because the requirement document
<http://www.ietf.org/internet-drafts/draft-ietf-pce-inter-layer-req-00.txt>
does not consider such model -

more generically i still believe this effort should concentrate on path 
computation (role of the PCE functionality)

thanks,
- dimitri.

	Title		: PCE Applicability for Inter-Layer MPLS and GMPLS Traffic 
Engineering

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 the applicability of 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).

	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.
