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.

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 Pages : 0 Date : 2006-10-22 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).

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. --------------------- Original Message Ends --------------------
