摘要
针对ASON网络恢复容量问题,建立了相应的数学模型,并提出了一种基于分布估计的恢复容量优化算法。与传统恢复容量算法相比,该算法在可行解搜索空间及计算量上大大降低,为算法在工程上的实现提供了可行性。仿真实验结果表明,提出的新算法搜索效率高,求解速度快,能够获得高质量的全局近似最优解,具有较强的实用性。
In order to solve the problem of ASON restoration capacity assignment, the corresponding mathematical model was established,and a new optimization algorithm based on estimation of distribution algorithm was presented. Compared with other restoration capacity methods, this algorithm reduces the calculation work significantly, which facilitates the application of algorithm on projects. Simulation results show that the near global optimal solution can be easily obtained and the solution is definitely satisfactory in engineering.
