Abstract
Example embodiments include a method for monitoring an optical network. The method provides received network data to a network model, which determines if there is an inconsistency within the optical network. The network models include a statistical model and a detailed-physical model, both of which model amplifier physics.
Claims18
A method for automatic monitoring of an optical network, the method comprising:
- receiving optical network data at a monitoring station, the received optical network data including at least measured optical network data for a span of the optical network;
- and
- determining whether the received optical network data is consistent with modeled optical network data determined from at least one optical network model, the optical network model modeling the physics of amplifiers in a span of the optical network.
A computer readable medium encoded with a method for automatic monitoring of an optical network, the method comprising:
- receiving optical network data at a monitoring station including at least measured optical network data for a span of the optical network;
- and
- determining whether the received optical network data is consistent with modeled optical network data determined from at least one optical network model, the optical network model modeling the physics of amplifiers in a span of the optical network.
A monitoring station comprising:
- receiver for receiving optical network data including at least measured optical network data for a span of the optical network;
- and
- controller for determining whether the received optical network data is consistent with modeled optical network data determined from at least one optical network model, the optical network model modeling the physics of amplifiers in a span of the optical network.
