Optical Burst Switching (OBS) technology has been proposed as a promising switching solution for the terabit bandwidth utilization in next-generation Wavelength Division Multiplexing (WDM) optical transport network. Control architecture and contention resolution are the main issues faced by the optical burst switching networks. This paper only taking care of the contention problem and to overcome this issue the authors propose pre-deflection routing with blocking probability estimation scheme for optical burst switch networks. In this paper, pre-deflection routing approach has been proposed in which routing is carried out in two ways, Shortest Path First (SPF) and Least Hop First (LHF) routing to forward the clusters and canoes respectively.
