Estimation of Distribution Algorithm for Dynamic RWA in ASON
In order to solve dynamic routing and wavelength assignment(RWA)problem in ASON,the corresponding network model is established,and a new optimization algorithm based on estimation of distribution algorithm is presented.Compared with shortest path algorithm,this algorithm reduces the calculation work significantly,which facilitates the application of algorithm on projects.Simulations showed that a lower blocking probability and the near global optimal solution can be achieved and the solution is definitely satisfactory in engineering.
