A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF.
Title : A Framework for MPLS in Transport Networks
Author(s) : M. Bocci, et al.
Filename : draft-ietf-mpls-tp-framework-07.txt
Pages : 46
Date : 2009-12-22
This document specifies an architectural framework for the
application of Multiprotocol Label Switching (MPLS) to the
construction of packet-switched equivalents of traditional circuit-
switched carrier networks. It describes a common set of protocol
functions - the MPLS Transport Profile (MPLS-TP) - that supports the
operational models and capabilities typical of such networks,
including signaled or explicitly provisioned bi-directional
connection-oriented paths, protection and restoration mechanisms,
comprehensive Operations, Administration and Maintenance (OAM)
functions, and network operation in the absence of a dynamic control
plane or IP forwarding support. Some of these functions are defined
in existing MPLS specifications, while others require extensions to
existing specifications to meet the requirements of the MPLS-TP.
This document defines the subset of the MPLS-TP applicable in general
and to point-to-point paths. The remaining subset, applicable
specifically to point-to-multipoint paths, are out of scope of this
document.
This document is a product of a joint Internet Engineering Task Force
(IETF) / International Telecommunications Union Telecommunications
Standardization Sector (ITU-T) effort to include an MPLS Transport
Profile within the IETF MPLS and PWE3 architectures to support the
capabilities and functionalities of a packet transport network as
defined by the ITU-T.
