The IESG has approved the following document: - 'Framework for PCE-Based Inter-Layer MPLS and GMPLS Traffic Engineering ' <draft-ietf-pce-inter-layer-frwk-10.txt> as an Informational RFC This document is the product of the Path Computation Element Working Group. The IESG contact persons are Ross Callon and Adrian Farrel. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-pce-inter-layer-frwk-10.txt Technical Summary A network may comprise multiple layers. In some cases it may be valuable to globally optimize network resource 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 used to achieve inter-layer traffic engineering. This document describes a framework for applying the PCE-based architecture to inter-layer Multiprotocol Label Switching (MPLS) and Generalized MPLS (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). Working Group Summary Good consensus reported (see PROTO writeup in the tracker). Document Quality This document provides an informative framework and as such is not subject to implementation, but rather is useful in the ongoing work of the PCE working group. Personnel JP Vasseur is the Document Shepherd for this document. Ross Callon is the Responsible Area Director.
