     MPLS Transport Profile (MPLS-TP) Linear Protection to Match the        Operational Expectations of Synchronous Digital Hierarchy,   Optical Transport Network, and Ethernet Transport Network Operators


   This document describes alternate mechanisms to perform some of the    functions of MPLS Transport Profile (MPLS-TP) linear protection    defined in RFC 6378, and also defines additional mechanisms.  The    purpose of these alternate and additional mechanisms is to provide    operator control and experience that more closely models the behavior    of linear protection seen in other transport networks.

   This document also introduces capabilities and modes for linear    protection.  A capability is an individual behavior, and a mode is a    particular combination of capabilities.  Two modes are defined in    this document: Protection State Coordination (PSC) mode and Automatic    Protection Switching (APS) mode.

   This document describes the behavior of the PSC protocol including    priority logic and state machine when all the capabilities associated    with the APS mode are enabled.

   This document updates RFC 6378 in that the capability advertisement    method defined here is an addition to that document.
