    abstract =  {Dynamic Multi-Segment Pseudowire (MS-PW) setup through an explicit path may be required to provide a simple solution for 1:1 protection with diverse primary and backup MS-PWs for a service, or to enable controlled signaling (strict or loose) for special MS-PWs. This document specifies the extensions and procedures required to enable dynamic MS-PWs to be established along explicit paths.},
