摘　　要：传统的量子通信网络采用空分机制,受链路中密钥分发率最低的链路限制。在大规模的量子通信网络中,链路资源浪费将更为显著,呼损率也很高。提出一种结合了分布式链路聚合算法和分布式业务聚合算法,可以支持多种业务,提供第三层路由功能以及服务质量保证的量子通信网络的路由策略。基于OPNET对呼损率的进行了仿真验证。结果表明,在保证安全性的同时可以提高瓶颈链路速率,降低系统呼损率,提高了服务质量。Traditional quantum communication network using an air separation mechanism,is limited by the link with low-est key distribution rate. In large-scale quantum communication networks,the link-resource waste is more significant,and callloss rate is high. A quantum communication network routing strategy is proposed,which combines with distributed link aggrega-tion algorithm and distributed business aggregation algorithm,supports a variety of business,and provides a third layer routingfunction and service quality assurance. A call loss rate simulation verification based on OPNET was carried. The results showthat the strategy can increase bottleneck link velocity,reduce system call loss rate and improve the service quality,while thesafety is ensured.
