摘　　要：随着民机空地传输网络的高速发展,未来航空机载数据传输需要支持分级高速可靠通信。为了满足不同应用的传输质量需求,面向空地传输网络中的多种通信链路,设计了基于改进令牌桶算法的分级协同流控模型,并提出了针对传输层、网络层不同优先级队列的协同流控调度机制,实现了机载数据空地分级可靠传输。仿真实验表明该模型及算法是高效可行的。With the rapid development of the air-ground transmission network of civil aircraft,the future airborne data transmission needs to support multi-level、high-speed and reliable communication.To meet the transmission quality requirements of different applications,a multi-level cooperative flow control model based on improved token bucket algorithm is designed for various communication links in the air-ground transmission network,and a cooperative flow control scheduling mechanism for different priority queues in the transport layer and the network layer is proposed to realize multi-level and reliable transmission of airborne data.Simulation results indicate that the model and algorithm are efficient and feasible.
