Internet Engineering Task Force (IETF) D. Frost, Ed. Request for Comments: 5960 S. Bryant, Ed. Category: Standards Track Cisco Systems ISSN: 2070-1721 M. Bocci, Ed. Alcatel-Lucent August 2010 MPLS Transport Profile Data Plane Architecture Abstract The Multiprotocol Label Switching Transport Profile (MPLS-TP) is the set of MPLS protocol functions applicable to the construction and operation of packet-switched transport networks. This document specifies the subset of these functions that comprises the MPLS-TP data plane: the architectural layer concerned with the encapsulation and forwarding of packets within an MPLS-TP network. 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.

Introduction The MPLS Transport Profile (MPLS-TP) is the set of functions that meet the requirements [RFC5654] for the application of MPLS to the construction and operation of packet-switched transport networks. MPLS-based packet-switched transport networks, and the overall architecture of the MPLS-TP, are defined and described in [RFC5921]. It is assumed that the reader is familiar with that document. This document defines the set of functions that comprise the MPLS-TP data plane: the architectural layer concerned with the encapsulation and forwarding of packets within an MPLS-TP network. This layer is based on the data plane architectures for MPLS ([RFC3031] and [RFC3032]) and for pseudowires [RFC3985].Show full document text
