摘　　要：针对量子密钥分发网络中量子密钥资源均衡应用问题,设计了一种路由改进方案,采用分段路由技术减少QKD网络密钥中继节点的流表开销,同时改进Yen算法的K最短路径,加入链路密钥剩余量和路由跳数路由参数,均衡密钥资源负载。经过仿真实验,验证了分段路由方案和改进的路由选择算法的合理性和可行性。For the issue of quantum key resource balanced application in quantum key distribution network,an improved routing scheme is designed,where the segment routing technology is adopted to reduce the flow table expenses of key relay nodes in QKD network,and the K shortest path of the Yen algorithm is improved by adding a link key remaining amount and a route hop count to balance the load of the key resource.Simulation results validate the reasonability and feasibility of the segment routing scheme and the improved routing algorithm.
