Claim Text:
1. A method, comprising: determining a bandwidth of a data stream to be transmitted; identifying a set of available spectral fragments, each of the available spectral fragments being defined by a respective bandwidth size; allocating at least a portion of the available spectral fragments, as a set of allocated spectral fragments, to support the data stream; dividing the data stream into a set of output sub-streams, the output sub-streams being associated with respective ones of the allocated spectral fragments; modulating the respective output sub-streams to provide respective modulated signals adapted for transmission via the respective allocated spectral fragments; monitoring, for at least one of the respective allocated spectral fragments, data indicative of channel performance of a respective channel associated with the respective allocated spectral fragment; based on identification of degraded channel performance of one of the channels associated with one of the allocated spectral fragments, adapting one or more parameters associated with transmission of the one of the allocated spectral fragments to compensate for the identified degraded channel performance, the one or more parameters associated with transmission of the one of the allocated spectral fragments including a forward error correction (FEC) rate; and based on a determination that the degraded channel performance of the one of the channels associated with one of the allocated spectral fragments exceeds a threshold level, selecting a backup spectral fragment for use by the modulated signal associated with the one of the allocated spectral fragments.
