RFC 4257: Framework for Generalized Multi-Protocol Label Switching (GMPLS)-based Control of Synchronous Digital Hierarchy/Synchronous Optical Networking (SDH/SONET) Networks
In plain English — editorial summary, not part of the RFC
Generalized Multi-Protocol Label Switching (GMPLS) is a suite of protocol extensions to MPLS to make it generally applicable, to include, for example, control of non packet-based switching, and particularly, optical switching. One consideration is to use GMPLS protocols to upgrade the control plane of optical transport networks. This document illustrates this process by describing those extensions to GMPLS protocols that are aimed at controlling Synchronous Digital Hierarchy (SDH) or Synchronous Optical Networking (SONET) networks. SDH/SONET networks make good examples of this process for a variety of reasons. This document highlights extensions to GMPLS-related routing protocols to disseminate information needed in transport path computation and network operations, together with (G)MPLS protocol extensions required for the provisioning of transport circuits. New capabilities that an GMPLS control plane would bring to SDH/SONET networks, such as new restoration methods and multi-layer circuit establishment, are also discussed. This memo provides information for the Internet community.
