摘要 针对基于光正交频分复用(OFDM)的频谱灵活光网络中的组播路由问题,提出了一种调制格式可变的组播路由与频谱分配算法(MV-MRSA),并进行了仿真分析。与传统的组播路由与频谱分配算法(MRSA)和距离自适应的组播路由与频谱分配(DA-RSA)算法相比,MV-MRSA算法能够有效地提高业务成功率和频谱资源利用率。 In this paper, for the multicast routing problem that based on optical orthogonal trequency division multiplexing (OFDM) in spectrum flexible optical network, we propose a modulation-variable enabled-multi- cast routing and spectrum assignment (MV-MRSA), and make simulation analysis. Compared with multicast routing and spectrum assignment (MRSA) and distance adaptive multicast routing and spectrum assignment (DA-RSA) algorithms, MV-RSA algorithm can effectively improve the rate of success business and spectrum resource utilization.
