多域光网络拓扑聚合算法的设计与仿真

Design and simulation of multi domain optical network topology aggregation algorithm

针对聚合算法相对失真性能较差的问题,提出一种多域光网络拓扑聚合算法。对单个域实施赋权,以拟合多域光网络的逻辑物理路径。进一步压缩代表点集合,在坐标系中拟合代表点即拟合楼梯,通过拟合结果构造多域光网络的全连通图,运用获取的星形拓扑实施多域光网络拓扑聚合,实现多域光网络拓扑聚合算法的设计。为了验证算法的相对失真性能设计对比实验,实验结果表明,该算法相对失真性能优于传统网络拓扑聚合算法,更适用于多域光网络的拓扑聚合。

In order to solve the problem of poor distortion performance of aggregation algorithm,a multi domain optical network topology aggregation algorithm is proposed.A single domain is weighted to fit the logical physical path of a multi domain optical network.Further compress the set of representative points,fit the representative points in the coordinate system,that is,fit the stairs,construct the all connected graph of the multi domain optical network through the fitting results,implement the multi domain optical network topology aggregation by using the star topology obtained,and realize the design of the multi domain optical network topology aggregation algorithm.In order to verify the relative distortion performance of the algorithm,the experimental results show that the relative distortion performance of the algorithm is better than the traditional network topology aggregation algorithm,and more suitable for the topology aggregation of multi domain optical networks.
