A Dynamic RWA Algorithm for Photonic Networks which Takes Account of Future Demand
نویسندگان
چکیده
A new adaptive RWA (Routing and Wavelength Assignment) algorithm is proposed, which may be used in photonic networks with no wavelength conversion. The problem we address is how to increase the utilization of WDM network resources by taking account of future demand efficiently. In the proposed method, blocking probability is minimized by taking account of future path establishment, using a method for which the computational load is reasonable. Using simulations, we compare the performance of the proposed RWA algorithm with existing methods including fixed-alternate routing and adaptive routing. The results demonstrate that the proposed algorithm can achieve much better blocking performance and the most efficient use network resources.

One of the most important technical problems in optical WDM network is the dynamic routing and wavelength assignment (dynamic RWA) problem, which is to set up lightpaths and assign wavelengths dynamically in order to establish a channel between optical source and destination nodes. Previous studies have solved many variations of the dynamic RWA problem under the assumption of ideal conditions r...

Optical networks form the foundation of today’s information infrastructure. Current generation optical networks consist largely of point-to-point electronically transmitted links which switch between nodes and repeaters. There is a trend in optical networking to move from the current generation opaque networks toward transparent networks. Transparent networks use only optical devices, eliminati...
