    abstract =  {This document specifies an extension to the identifiers to be used in the Transport Profile of Multiprotocol Label Switching (MPLS-TP). Identifiers that follow IP/MPLS conventions have already been defined. This memo augments that set of identifiers for MPLS-TP management and Operations, Administration, and Maintenance (OAM) functions to include identifier information in a format typically used by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T).},
