The SSM based synchronisation routing is not state of the art, but a
fairly well understood and documented thing. The ITU-T G.781 is
available for free download. The ETSI documents is also available for free.
SSM based synchronisation routing suffers from several deficiencies and
essentially requires a management system to handle the error case and
reconfigure the network.
The SSM processing essentially allows for the network nodes to act as
the first line of defence in quick interaction and if properly
configured will do it almost right most of the time. It's not bad, but
not what we expect from networks these days.
