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.
