Evolution of dynamic routing wavelength code assignment in WDM/OCDM OBS network

This paper proposes and investigates the performance of a dynamic routing and wavelength code assignment (RWCA) algorithm using hybrid technology with wavelength and optical code division multiplexing (WDM/OCDM) for Optical Burst Switching (OBS) network. An OCDM-based multigranularity optical cross-connect (MG-OXC) is used to enable the better granularity in optical path (wavelength and code) switching than the wavelength-based path. The results show that Random-Random heuristic has a better performance when the burst blocking probability as a function of traffic load is studied. In addition, show that WDM/OCDM technology increase the capacity and scalability in the optical network.
