Abstract: Current research interests have diverted towards the efficient priority-based routing and wavelength assignment strategy in order to enhance the quality of service in the distributed optical networks. The traditional RWA techniques such as Adaptive Routing (AR), Non priority based RWA schemes etc. are lacking of capability to reduce both the blocking probability and average end to end delay simultaneously during the transmission of networks. In this paper, an Adaptable Priority-based RWA (APRWA) schemes for optical network has been demonstrated and evaluated by utilizing the performance enhancing metric such as reduction in hop count while simultaneously handling distinguishable traffic volume. The simulation result shows considerable reduction both in the blocking probability (approx. 25%) as well as in average end to end delay near around (15 msec.) in comparison to conventional RWA techniques.
