摘要:

量子保密通信网络是一种新兴的安全网络。如何通过合理的流量规划方法提升量子保密通信网络骨干链路的带宽利用率、提升网络性价比是一个新问题。分析了量子保密通信网络流量规划的特殊性,给出了一种流量规划模型,可以实现下列 3 个方面的目标:在确定网络骨干链路密钥分发带宽的情况下,可以实现用户广域加密通信带宽的规划;借助路由规划可以提升用户广域加密通信带宽和量子链路密钥分发带宽的利用率;可以实现对网络瓶颈量子链路密钥分发带宽的合理调整。最后,通过数值模拟示例演示了本文所提出的流量规划方法的应用。

Abstract:

Quantum secure communication network is a new kind of security network.It is a new problem that how to improve the bandwidth utilization ratio of the backbone link of quantum secure communication network and the network performance-price ratio by reasonable traffic planning method.The particularity of traffic planning in the quantum secure communication network was analyzed,and a traffic planning model was given.Based on this model,the user wide area encrypted communication bandwidth could be planned in the case of determining the key distribution bandwidth of the backbone link.At the same time,the model could be used to adjust the bandwidth of key distribution in network bottleneck links and improve the network performance.Finally,the application of the proposed flow planning method was demonstrated by numerical simulation.

Key words: quantum secure communication network, traffic planning, backbone link
