Abstract
The suite of protocols that defines Multi-Protocol Label Switching is in th e process of enhancement to generalize its applicability to the control of optical networks. One area of prime consideration is to use these generaliz ed MPLS protocols in upgrading the control plane of optical transport netwo rks. This article describes those extensions to MRS directed toward control ling SDH/SONET networks. SDH/SONET networks are ideal candidates for this p rocess since they possess a rich multiplex structure, and a variety of prot ection/restoration options are well defined and widely deployed. We discuss the extensions to MPLS routing protocols to disseminate information needed for transport path computation and network operations, and the extensions to MPLS label distribution protocols needed for provisioning of transport c ircuits.
