Title:
A DEVICE OF REALIZING OPTICAL SUPERVISORY CHANNEL INFORMATION TRANSMISSION AND A SYSTEM AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/009188
Kind Code:
A1
Abstract:
A device of realizing optical supervisory channel information transmission
and a corresponding system and method are disclosed; the said device comprises:
an optoelectronic converter, a level converter, an internal level converter,
a physical layer information preprocessor, a switch of any layer from layer 2
to layer 7, and a route generating and switching controller; the said system comprises:
a channel switching device, a controlling device, a multiplexing/demultiplexing
device; the method includes: the layer 3 switch receives the optical supervisory
channel information, then according to the correspondence of its own port and
each nodes in the network, the switch selects a suitable route to transmit the
said information. The present invention does not establish a fixed link between
the source and the destination, after finishing the transmission, the bandwidth
resource will not be consumed anymore so that the bandwidth resource can be fully
utilized. At the same time, a multi-layer switching technique is applied by the
invention, therefore, the bandwidth resource provided by the system can be further
employed to dynamically adapt to the change of the network topology.
