Contention Problem in Optical Burst Switching Network

Optical burst switching (OBS) is a promising switching technology for next-generation Internet backbone networks. One of the key problems hindering the realization of optical burst switching (OBS) technology in the core networks is the losses due to contention among the bursts at the core nodes. Wavelength Conversion is an effective contention resolution technique used to reduce the number of bursts loss. In this paper, we investigate the problem of burst loss in optical burst switching (OBS) networks. The main goal of this work is to minimize burst loss rate in the network by using wavelength converters and by increasing number of channel wavelengths.
