Abstract:
1. One or more non-transitory computer-readable media having instructions stored thereon that, responsive to execution by one or more processors, cause the one or more processors to perform operations to defragment an optical network, the operations comprising: selecting one of a plurality of frequency slots as a selected frequency slot and another of the frequency slots as an end frequency slot, the frequency slots each spanning a portion of an optical spectrum of an optical network; assigning each of a plurality of optical signals within the optical network to one or more of the frequency slots; constructing a frequency slot dependency map based on the assignation of the optical signals to their respective frequency slots, wherein identifying a release of the second optical signal; and in response to the release of the second optical signal, reassigning the first optical signal associated with the released second optical signal to one or more of the frequency slots of the second set of the frequency slots based on the association of the first and second optical signals in the frequency slot dependency map.
