摘要
摘要:为了提高无色无向无冲突灵活的可重构光分插复用器(CDC-F ROADM)节点的弹性光网络IP组播频谱-能耗效率，该文提出一种全光组播能效调度算法(AMEESA)。在算法路由阶段，考虑能耗和链路频谱资源使用情况设计链路代价函数，构建最小代价光树算法组播光树。在频谱分配阶段，设计基于高效光谱分辨率(HSR)光树中间节点频谱转换方法，选择节能频谱转换方案为组播光树分配频谱块资源。仿真分析表明，所提算法能有效提升网络能效，降低IP组播带宽阻塞率。

Abstract:In order to improve multicast’s spectrum energy-efficient of elastic optical network configured with Colorless, Directionless and Contentionless-Flexible Reconfigurable Optical Add/Drop Multiplexer (CDC-F ROADM) nodes, an All-optical Multicast Energy Efficiency Scheduling Algorithm (AMEESA) is proposed. In the routing phase, considering both energy consumption and link spectrum resource utilization, the link cost function is designed to establish the multicast tree with the least cost. In the spectrum allocation phase, a spectrum conversion method based on High Spectral Resolution (HSR) is designed by changing the spectrum slot index of adjacent links according to links availability of spectrum blocks. And an energy-saving spectrum conversion scheme is selected to allocate spectrum block resources for the multicast tree. Simulation analysis shows that the proposed algorithm can effectively improve the network energy efficiency and reduce the bandwidth blocking probability of IP multicast.
