Sparse partial optical Code and Wavelength Conversion architecture in hybrid WDM/OCDM OBS networks

The performance of Optical Code/Wavelength Conversion (OCWC) switch architectures are investigated in this work. We employed hybrid technologies within in Optical Burst Switching (OBS) networks, which include wavelength and optical code division multiplexing. The simulated results demonstrate the concomitant increase of optical codes per wavelength and the utilization of Sparse Partial Optical Code/Wavelength Conversion. Both lead to a considerable decrease of the Burst Blocking Probability (BBP). In addition, such hybrid approach also improves the utilization of network resources.
