Abstract

In order to reduce the complexity of the optical switching nodes at a reasonable level and increase its capacity at the same time, the concept of multi-granularity was proposed. With the utilization of multi-granularity switching, the number of ports for the optical switching matrices can be decreased. In this paper, we consider the two-stage multiplexing that includes the wavelength multiplexing and waveband multiplexing. A simple algorithm that can realize the grouping from wavelengths into wavebands efficiently is proposed. As the decreased number of the optical switching matrices' ports is determined partially by the number of the nodes passing the waveband path, the length of the waveband path is considered in this algorithm. To group as more wavelengths as possible into wavebands, all the wavelength paths will be evaluated in the algorithm as long as they have common sub-path. This algorithm is also tested in two networks with six nodes, and the saving number of the switching matrices' ports is compared with which using only the one-stage wavelength multiplexing.
