Abstract

In order to achieve nonblocking connection, all the switching networks are designed to provide connections of full permutations. To reduce the hardware complexity, we propose designing wavelength-exchanging cross connect (WEX) to support sufficient permutations instead of full permutations. In this paper, we propose an algorithm to construct an optimal Benes WEX architecture with sufficient permutations. The idea is to select a minimal number of switching elements in a Benes WEX so that all connections of sufficient permutations can be provided. Our case study results show that the architectures of our proposed WEX based on sufficient permutations in the cases of 2 and 4 wavelengths in each fiber can to save up to half switching elements compared with that of the existing Benes WEXs based on full permutations.
