The IESG has approved the following document: - 'MPLS-TP Identifiers' (draft-ietf-mpls-tp-identifiers-07.txt) as a Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-tp-identifiers/ Technical Summary This document specifies identifiers for MPLS-TP objects. Included are identifiers which are compatible with existing IP, MPLS, GMPLS, and Pseudowire definitions. The identifiers apply to the ends of Label Switched Paths (LSPs) and the ends of Pseudowires. They also apply to the identifiable objects within Operations, Administration, and Maintenance (OAM) Maintenance Entities. Working Group Summary This document defines a format for MPLS-TP LSP Identifiers based on global node IDs (ie, IP addresses). A previous version of this draft included MPLS-TP identifiers based on ICCs (ITU Carrier Codes). However, late in the process, technical problems with the global uniqueness of the ICC format were discovered. Due to the anticipated delay in getting these issues resolved, the ICC based identifiers have been removed from the document. It is anticipated that a further document handling ICC based identifiers will be developed once the issues have been resolved by the ITU-T. There was a request from a few people to allow use of a global node ID for one end of an LSP and an ICC based ID for the other end of the same LSP. After extensive discussion on the MPLS WG email list, there was a clear consensus to progress the document without support for mixed use. Clearly this could not be done in any case until the issues with the ICC based identifier have been resolved. Future work on "mixed mode" identifiers was not ruled out. Other than these issues there was little controversy, and the document is needed for important ongoing work on MPLS-TP. Document Quality The document has been extensively reviewed and is an important basis for ongoing work on MPLS-TP. Many of the identifiers using standard IETF addressing fields are already implemented by default in MPLS and pseudowire systems. A number of vendors are building MPLS-TP solutions and will include identifier formats described in this document. Personnel Ross Callon (rcallon@juniper.net) is the Document Shepherd.
