Abstract:
1. A method for provisioning bandwidth in an optical data network, comprising: allocating, by a processor, at least one channelized connection to carry a first incremental bandwidth between a first layer 2/3 device and a second layer 2/3 device through an optical switching device connected to the first layer 2/3 device; determining, by the processor, an additional required bandwidth between the first layer 2/3 device and the second layer 2/3 device, wherein a total required bandwidth, including the first incremental bandwidth and the additional required bandwidth, exceeds a threshold bandwidth; allocating, by the processor, a direct channel to carry the total required bandwidth between the first layer 2/3 device and the second layer 2/3 device, bypassing the optical switching device; wherein allocating at least one channelized connection to carry the first incremental bandwidth, further comprises:
