文摘

A wavelength division multiplexing based multicast Benes switching network considers an input signal on inlets with the given wavelength to one or more fiber outlets with wavelength conversion in the optical domain. The main challenge in the design of multicast routing and wavelength assignment is to reduce the complexity of wavelength conversion without affecting switch capability and no cross-talk signal quality using the Benes network. The proposed design of multicast routing and wavelength assignment wavelength conversion using Benes network complexity is 4Flog₂W/2 and switching complexity of O(Flog₂W/2). The performance loss in terms of throughput, delay, and packet loss of the proposed low-complexity method using output queuing multicast interconnection network. We prove that W > 64 conversion complexity of the optimal design is strictly lower than the existing system Copy route single channel and multicast channel. When we compare with different conversion techniques, the add/drop multicast Benes network and Mach–Zehnder Interferometer using Benes network complexity is higher because 2N × 2N design switching elements are required, and so double the amount of conversion is required. The proposed Multicast routing Wavelength assignment Benes technique achieves more than 80 % reduction in conversion complexity for the design of Benes network as compared to different wavelength conversion techniques.
