Abstract
In optical wavelengthdivision multiplexing WDM networks traffic can be unevenly distributed across the network causing inefficient utilization of resources To solve this problem an improved soft preemptive SP scheme is proposed by considering dynamic resource distribution to deal with the uneven network utilization A novel unevenly distributed traffic model in crosstimezone networks is also presented to evaluate the efficiency of the new scheme Compared with other schemes such as normal shortest path first SPF routing and wavelength conversion WC the new proposed scheme results demonstrate significantly better performance with respect to the network utilization and overall network blocking probability
