MPLS Transport Profile User-to-Network and Network-to-Network Interfaces

Overview

RFC 6215, “MPLS Transport Profile User-to-Network and Network-to-Network Interfaces”, is an Informational document published in April 2011 by M. Bocci, L. Levrau, D. Frost. It updates RFC 5921. The canonical text is published by the RFC Editor.

Abstract

The framework for MPLS in transport networks (RFC 5921) provides reference models for the MPLS Transport Profile (MPLS-TP) Transport Service Interfaces, which are a User-to-Network Interface (UNI), and a Network-to-Network Interface (NNI). This document updates those reference models to show detailed reference points for these interfaces, along with further clarification of the functional architecture of MPLS-TP at a UNI and NNI.

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 as defined by the ITU-T. This document is not an Internet Standards Track specification; it is published for informational purposes.
