The Transport Profile for Multiprotocol Label Switching (MPLS-TP) is
being specified jointly by IETF and ITU-T. This document addresses
the functionality described in the MPLS-TP Survivability Framework
document and defines a protocol that may be used to fulfill the
function of the Protection State Coordination for linear protection.
Linear protection provides rapid and simple protection switching.
In a mesh network, linear protection provides a very suitable
protection mechanism because it can operate between any pair
of points within the network. It can protect against a defect in an
intermediate node, a span, a transport path segment, or an end-to-end
