摘　　要：在构建大规模量子密钥分发网络的过程中,为了提高在可信中继模式下密钥中继成功率、减少链路密钥消耗以及平衡网络负载,提出了一种基于桶重计算的量子密钥分发网络路由选择算法,并构建了基于软件定义网络SDN的网络架构模型。在网络源节点到目的节点所经过的所有路径中,根据计算Bucket权重即桶重作为路径优先级,控制器通过优先级选择最优路径;最后,对提出的路由选择方法进行仿真实验,验证了算法的合理性和可行性。In the process of building a large-scale quantum key distribution network,a routing algorithm based on bucket weight calculation for quantum key distribution network is proposed to improve the success rate of key relaying in trusted relay mode,reduce the link key consumption and balance the network load,and a network architecture model based on software-defined network SDN is constructed.Among all the paths from the source node to the destination node,the controller selects the optimal path by calculating the Bucket weight,that is the bucket weight as the path priority.The simulation results show that the proposed routing method is reasonable and feasible.
