A wave-channel balanced algorithm for electric power optical transport network

A wave-channel balanced dynamic RWA algorithm presented in this paper based on the business for electric power optical transport network. This algorithm is designed to solve the routing and wavelength assignment problems of multibusiness request in the complex power optical transport network. This algorithm made the classification of business requests and set the priority of each request according to network topology and business request status. After setting the priority the proposed algorithm completed the wavelength assignment through domain selection and intradomain routing. The simulation results showed that the algorithm can effectively reduce the blocking rate of network requests and at the meantime increase utilization of the optical transport network resource.
