Performance Evaluation of the WSW1 Switching Fabric Architecture with Limited Resources

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 1062)


The evaluation of the Wavelength-Space-Wavelength (W-S-W) switching fabrics is considered in this paper. The combinatorial properties of such switching fabrics have been discussed in several papers. The strict-sense nonblocking (SSNB) conditions require tunable spectrum converters (TSCs) of wide conversion range in order to utilize all the interstage frequency slot units (FSUs). In this paper, we simulate the mentioned switching fabric and estimate the required numbers of both frequency slot units and tunable spectrum converters so the internal blocking probability is no more than \(10^{-10}\).
