Claim Text:
1. A method for allocating optical spectrum bandwidth resources, comprising: determining, by a processor of an apparatus for allocating the optical spectrum bandwidth resources, a bandwidth of a base optical channel transmission unit (OTUbase) according to an optical-layer frequency grid bandwidth and a carrier spectrum efficiency; constructing, by the processor, a bandwidth-adjustable higher order optical channel transmission unit (HO OTUflex) according to a bandwidth of customer service data and the bandwidth of the OTUbase, wherein the bandwidth of the HO OTUflex is a first integer multiple of the bandwidth of the OTUbase; mapping, by the processor, the customer service data to a payload area of the HO OTUflex and encapsulating overhead information; and modulating the HO OTUflex that carries the customer service data to a second integer number of optical channel carriers, by implementing the following:
