Internet Engineering Task Force (IETF) D. Fedyk Request for Comments: 5828 Alcatel-Lucent Category: Informational L. Berger ISSN: 2070-1721 LabN L. Andersson Ericsson March 2010 Generalized Multiprotocol Label Switching (GMPLS) Ethernet Label Switching Architecture and Framework Abstract There has been significant recent work in increasing the capabilities of Ethernet switches and Ethernet forwarding models. As a consequence, the role of Ethernet is rapidly expanding into "transport networks" that previously were the domain of other technologies such as Synchronous Optical Network (SONET) / Synchronous Digital Hierarchy (SDH), Time-Division Multiplexing (TDM), and Asynchronous Transfer Mode (ATM). This document defines an architecture and framework for a Generalized-MPLS-based control plane for Ethernet in this "transport network" capacity. GMPLS has already been specified for similar technologies. Some additional extensions to the GMPLS control plane are needed, and this document provides a framework for these extensions.
