摘　　要：为了优化大容量星载标签交换机的设计,提出了一种星地流控机制,根据星载交换机存储资源使用状态调整地面网络设备队列调度权重,降低星载交换机存储资源使用量和丢包率。使用网络仿真软件(NS2)仿真分析了地面网队列调度机制对星载交换机存储资源需求和丢包率等关键指标的影响,为星载标签交换机和星地协同网络的设计提供了参考。To optimize the design of high capacity on boara switch, a flow of satellite and terrestrial was proposed which can adjust the queue scheduling weight of ground network devices to reduce the usage amount of storage resource and lossrate of the packet of on board switch. By using NS2, analysis was made of the influence of the queue scheduling mecha- nism of ground network to some key indexes of on board switch such as the requirement of stor- age resource and lossrate of the packet and so on, which provide reference for the design of on board label switch and synergic satellite and terrestrial network.
