MPLS-TP Control Plane Framework
The MPLS Transport Profile (MPLS-TP) supports static provisioning of transport paths via a Network Management System (NMS), and dynamic provisioning of transport paths via a control plane. This document provides the framework for MPLS-TP dynamic provisioning, and covers control plane addressing, routing, path computation, signaling, traffic engineering, and path recovery. MPLS-TP uses GMPLS as the control plane for MPLS-TP LSPs. MPLS-TP also uses the control plane for Pseudowires (PWs). Management plane functions such as manual configuration and the initiation of LSP setup are out of scope of this document. This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunication Union Telecommunication Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and Pseudowire Emulation Edge-to-Edge (PWE3) architectures to support the capabilities and functionalities of a packet transport network as defined by the ITU-T. This Informational Internet-Draft is aimed at achieving IETF Consensus before publication as an RFC and will be subject to an IETF Last Call. [RFC Editor, please remove this note before publication as an RFC and insert the correct Streams Boilerplate to indicate that the published RFC has IETF consensus.]
