摘　　要：为了给将来量子密钥分发(QKD)网络的实际建设提供理论支持,依据QKD网络的实际功能组成重点分析了其功能模型,借助分层网络的思想规范了其接口机制,进而通过引入软件定义网络技术提出了一种集中管控的QKD发网络体系结构并给出了它的工作流程,最后通过实际搭建QKD网络模型实现了QKD网络上节点间的QKD功能,验证了提出的QKD网络体系结构与接口机制的可行性。In order to provide theoretical support for the practical construction of quantum key distribution(QKD)network in the future,this paper focuses on the analysis of its functional model according to the actual functional composition of QKD network,standardizes its interface mechanism with the idea of hierarchical network,and then proposes a centrally controlled QKD network architecture by introducing software defined network technology,and gives its working process.After that,this paper realizes the function of QKD between nodes in QKD network by building the model of QKD network,and verifies the feasibility of the architecture and interface mechanism of QKD network proposed in this paper.
