An automated optical transport system is provided which provides for
automatic discovery of system components, automatic inventory of system
components, automatic topology detection, automatic provisioning of
channels, and automatic characterization and tuning of system components
and fiber. The invention provides automation capability through inclusion
of management card capabilities at each station which communicates
through a reverse propagating service channel. Dynamic and propagation
direction independent segments are provided in conjunction with a
token-based scheme to repeatedly tune, update and monitor the transport
system.
