Considering the constantly changing network resources and randomly generated spectrum fragmentation problem, a dynamic routing, modulation, and spectrum assignment based on the fuzzy logic control (RMSA-FLC) algorithm is proposed in this paper. A fuzzy logic control (FLC) system based on the degree of fragmentation optimization and the degree of link selection is constructed. The path-control weight (PW) is achieved as the output of the FLC system, and the path and spectrum allocation scheme with the maximum PW is selected for the immediate reservation requests. The simulation results show that the proposed RMSA-FLC algorithm can effectively reduce the blocking probability and improve the spectrum resource utilization in a dynamic elastic optical network.
针对网络资源不断变化以及随机产生的频谱碎片问题,本文提出了一种基于模糊逻辑控制的动态路由、调制与频谱分配(RMSA-FLC)算法。构建了一个基于碎片优化程度和链路选择程度的模糊逻辑控制(FLC)系统。将路径控制权重(PW)作为FLC系统的输出,为即时预留请求选择具有最大PW的路径和频谱分配方案。仿真结果表明,所提出的RMSA-FLC算法能够有效降低阻塞概率,提高动态弹性光网络中的频谱资源利用率。
