摘　　要：为适应电力网中快速增长的灵活性和多样性业务,将弹性光网络技术引入到电力通信骨干网中,设计了针对不同优先级业务进行流量疏导的路由和频谱分配算法。算法定义了差异化的流量疏导指标,实现了对不同优先级业务的优化处理,并尽可能地减少了业务间的保护带宽。仿真结果表明,与传统无流量疏导的算法相比,本算法能够有效地减少最大频隙使用数和阻塞业务数。In order to provision a variety of flexible electrical service, elastic optical network technology is introduced into the power backbone network. A routing and spectrum allocation algorithm for services with different priority is designed in power backbone network. Considering different priority, the algorithm defines the differentiated traffic grooming strategies to minimize the guard band between different services. Compared with traditional no-traffic grooming algorithms, the simulation results show that a significant reduction is achieved, in maximum spectrum index and blocking on delay sensitive service.
