摘　　要：为降低系统成本,文章通过部分配置波长转换器的方法缓解国网OTN骨干网络的波长连续性限制,并保障波长的资源利用效率。对国网OTN网络中波长转换器配置问题进行了理论研究,详细阐述了子图+ADD算法及其改进算法的设计思想,对各个算法的性能进行分析,在国家电网公司大容量骨干光传输网拓扑上进行仿真,并给出波长转换设备的最佳配置方案。仿真结果表明,通过合理地部署波长转换单元,可达到与全波转换相近的性能指标。In order to reduce system cost, this paper releases the limit of wavelength continuity in state grid OTN backbone network by configuring wavelength converter partly, and guarantees the resource use efficiency of wavelength. Based on the theoretical research of the wavelength converter configuration in State Grid OTN Backbone Network, a detailed description of design idea about the subgraph ＋ADD algorithm and its improved algorithm is given. The performance of each algorithm is analyzed and the simulation is carried out on the large- capacity backbone optical transmission network in SGCC. Finally, the best configuration scheme of wavelength converter is given. The results show that a reasonable wavelength converter deployment can achieve similar perfbrmance with the full-wavelength conversion.
