An Optical Burst Switching Core Node Performance Analysis with Wavelength Conversion and Deflection Routing Capabilities
The most challenge problem in the Optical Burst Switching (OBS) core nodes is the burst loss due to a contention that occurred among the bursts. Wavelength conversion and deflection routing may be viable methods to resolve the burst contention problem and hence to improve the performance of an optical core switch. This paper proposes an OBS core node model with a combination of a wavelength conversion capability and the deflection routing technique to minimize the burst contention probability. First, the optimum values of adjusting the wavelength conversion capabilities and the level of deflection routing are investigated in a different contention resolution cases. Then, a performance analysis according to the effect of the different number of wavelength channels and variable burst length values has been studied at these optimum values. The performance measurement key is the average burst loss probability that performed by using steady-state occupancy probabilities and Poisson traffic model arrivals. Performance analysis results reveal that at the proposed switch contention resolution optimum values with different mean burst arrival rates could improve the OBS performance at high wavelength channels and small burst sizes.
