Abstract:
1. A method comprising: determining, for each of a plurality of packet-optical transport devices interconnected to form an optical transport system, a respective channel group size specifying a number of optical channels to reserve for each of the packet-optical transport devices from a total number of optical channels for the optical transport system, wherein the respective channel group size for each of the packet-optical transport devices is determined based on a bandwidth requirement for the respective packet-optical transport device; reserving, in accordance with the each of the determined channel group sizes, a set of optical channels for each of the packet-optical transport devices from an optical spectrum supported by the packet-optical transport devices, each of the reserved optical channels having an unassigned wavelength, and each of the sets of optical channels being associated with a different portion of the optical spectrum and having an spectral range that is based on the channel group size determined for the respective packet-optical transport device; and for each of the packet-optical transport devices, assigning a respective wavelength from the optical spectrum to one or more of the optical channels of the set of optical channels reserved for the packet-optical transport device to balance network traffic associated with the packet-optical transport device around a center of the portion of the optical spectrum associated with the set of optical channels reserved for the packet-optical transport device.
