“…To increase the network performance and treat with the data loss, the contention resolution strategies are an important issue in the OBS networks [15]. These strategies such as the wavelength conversion [16], fiber delay line [17], burst segmentation [18], and deflection routing [19] are suggested. The most effectively contention resolution technique is the wavelength conversion in the OBS networks.…”

In Wavelength Division Multiplexing (WDM), several wavelengths run on an optical fiber link that connects two optical switches. The multiple wavelengths are exploited that minimized the contention problem in the Optical Burst Switching (OBS) core node. Mathematical model is used in order to investigate the impact of the wavelengths numbers OBS core node. Two performance metrics are proposed such as the steady-state throughput and the probability of burst loss using steadystate occupancy probabilities and Poisson traffic model arrivals. Numerical results show that at different values of network traffic and some design parameters such as wavelength conversion capability and the mean arrival rate could reveal the OBS performance.
