Performance analyses of regular networks with limited number of wavelength converters by employing deflection routing

Optical node performance analysis in terms of number of wavelength converters for a multi-hop regular optical networks under deflection routing is presented in this paper. Based on 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 are 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.
