PSC protocol updates for non-revertive operation
This document optionally updates [RFC6378], "MPLS Transport Profile (MPLS-TP) Linear Protection", to change non-revertive operation to be aligned with the behavior defined in [RFC4427] and in an effort to satisfy the ITU-T's protection switching requirements. An operator command, Manual Switch to Working (MS-W) is also included to revert traffic to the working path in non-revertive operation.
