ABSTRACT:
In accordance with the teachings of the present invention, a system and method for managing wavelength drift in an optical network is provided. In a particular embodiment, the method includes receiving traffic in one or more optical channels transmitted by one or more transmitters, each channel having successive timeslots, each transmitter assigned to transmit in a channel in allocated timeslots in the channel. The method also includes determining whether the traffic received in a particular channel in a particular timeslot was transmitted by one of the transmitters that was not assigned to transmit in the particular channel. The method further includes, if the traffic in the particular channel was transmitted by one of the transmitters that was not assigned to transmit in the particular channel, identifying the transmitter that was not assigned to transmit but that did transmit in the particular channel, assigning the identified transmitter to transmit in the particular channel, and allocating timeslots in the particular channel to the identified transmitter.
