摘要
提出一种新型基于通信数据分组到达时间的拥塞避免算法,以数据分组的到达时间差异来判断网络带宽的拥塞情况,为发送端速率控制提供拥塞控制的依据。在模型控制中建立VTP虚拟传输协议,实现拥塞避免和实时传输协议之间解耦合。该算法通过对拥塞控制建模和优化,较好地解决了针对ad hoc网络的实时流媒体传输的带宽适应性难题。
This paper proposes a new congestion avoidance algorithm based on packet arrival time of communication data.The difference of arrival time of data packet was used to judge the congestion overuse and underuse of network bandwidth,which provided the basis of congestion control for sender rate control.VTP virtual transport protocol was established in model control to realize decoupling between congestion avoidance and real-time transport protocol.By modeling and optimizing the congestion control,this algorithm solves the bandwidth adaptability problem of real-time streaming media transmission in ad hoc network.
