    abstract =  {This document specifies the requirements necessary to manage the elements and networks that support an MPLS Transport Profile (MPLS-TP). This document is a product of a joint International Telecommunications Union - Telecommunications Standardization Sector (ITU-T) and Internet Engineering Task Force (IETF) effort to include a MPLS Transport Profile within the IETF MPLS architecture. The requirements are driven by the management functionality needs defined by ITU-T for packet transport networks.
