Performance Evaluation Of Advanced Wdm Networks With Optical Codes And Photonic Switching

We propose and evaluate performance of an innovative hybrid technology using wavelength and optical code division multiplexing (WDM/OCDM) for optical burst switching (OBS) advanced WDM networks. An architecture for the edge routers with fast optical circuit switching and virtual optical code/wavelength paths (VOCP/VWP) is described. We consider burst blocking probability (BBP) as a function of traffic load and various delays. Simulation results indicate that increasing the number of optical codes per wavelength considerably decreases BBP and latency, and also increases network throughput. © 2007 IEEE.187190Jue, J.P., Vokkarane, V.M., (2005) Optical Burst Switched Networks, Springer Science, , Boston, cBattestilli, T., Perros, H., An Introduction to Optical Burst Switching, IEEE (2003) Optical Comm, pp. 510-515Duser, M., Beyvel, P., Analysis of Dynamically Wavelength-Routed OBS Network Architecture (2002) J.
