The possibility of application the optical wavelength division multiplexing network for streaming multimedia distribution

In this paper, simulation is used to investigate the possibility of streaming multimedia distribution over optical wavelength division multiplexing (WDM) network with optical burst switching (OBS) nodes. Simulation model is developed using software tool Delsi for Delfi 4.0. Pareto generator is used to model real-time multimedia stream. The wavelength allocation (WA) method and the deflection routing are implemented in OBS nodes. Performance measures, packet loss and delay, are estimated in order to investigate the quality of multimedia service. Statistical analysis of simulation output is performed by estimating the confidence intervals for a given degree according to the Student distribution. Obtained results indicate that optical WDM network manages multimedia contents distribution in efficient way to give a high quality of service.
