Network survivability is the network's ability to restore traffic
delivery following failure of network resources or an attack on the
network. It plays a critical role in the delivery of guaranteed
services in transport networks to meet the requirements expressed in
Service Level Agreements (SLAs).
The Transport Profile of Multiprotocol Label Switching (MPLS-TP) is a
packet transport technology based on the MPLS data plane and re-using
many aspects of the MPLS management and control planes.
This document provides a framework for the provision of survivability
functions in the data plane of an MPLS-TP network using tools
provided by the management plane and the control plane as well as
techniques inherent in the data plane itself.
This document is a product of a joint International
Telecommunications Union (ITU)-IETF 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 International Telecommunications Union -
Telecommunications Standardization Sector (ITU-T).
