Analysis of ShuffleNets with limited number of wavelength converters employing deflection routing

Optical node performance analysis in terms of number of wavelength converters for a multihop optical ShuffleNet under deflection routing is presented. From the computed results for a given number of wavelengths, it is found that in order to achieve the minimum deflection probability at full load, the number of wavelength converters required is at most 60% of the number of wavelengths. Any additional wavelength converters would not be necessary in reducing the overall deflection probability. These upper-bound findings are indeed helpful for network engineers designing a cost-effective network node.
