The IESG has approved the following document: - 'MPLS-TP Applicability; Use Cases and Design' (draft-ietf-mpls-tp-use-cases-and-design-08.txt) as Informational RFC 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-use-cases-and-design/ Technical Summary This document provides applicability, use case studies and network design considerations for the Multiprotocol Label Switching Transport Profile (MPLS-TP). In the recent years, MPLS-TP has emerged as the technology of choice for the new generation of packet transport. Many service providers (SPs) are working to replace the legacy transport technologies, e.g. SONET/SDH, TDM, and ATM technologies, with MPLS-TP for packet transport, in order to achieve higher efficiency, lower operational cost, while maintaining transport characteristics. The use cases for MPLS-TP include Metro Ethernet access and aggregation, Mobile backhaul, and packet optical transport. The design considerations discussed in this document range from operational experience; standards compliance; technology maturity; end-to-end forwarding and OAM consistency; compatibility with IP/MPLS networks; multi-vendor interoperability; and optimization vs. simplicity design trade off discussion. The general design principle is to provide reliable, manageable, and scalable transport solutions. Working Group Summary This document has a strong support in the working group and has been well reviewed. The AD review resulted in significant restructuring of the document and revision of the text. The new document was taken back to the working group for discussion and a further last call. Document Quality This an informational document, it presents some use-cases and provides design guidelines, but it is not possible to say that there are implementations. The document has had the review that is needed, the working group last call was brought to the attention of SG15 in ITU-T. Personnel Loa Andersson is the document shepherd. Adrian Farrel is the responsible AD.
