摘要
无线网络因为误码丢包导致的错误拥塞使发送端降低发送速率,正确判断网络拥塞状态对网络性能非常重要,实时传输协议的速率控制单元丢包检测方案设置于无线网络和有线网络的边界上,它能够提供网络状况信息给源端,使得源端能够正确的判断网络拥塞状态。仿真实验证明,RTP/RCU的反馈信息可以较好的区分拥塞状况和误码丢包,使得速率控制和差错控制效率得到了较大提高。.
Wireless networks because the error packet loss caused by network congestion so that the sender reduces the sending rate, determine the correct state of network congestion on the network performance is very important, real-time transport protocol packet loss rate control unit inspection program set up in the wireless network and wired network on the border, which provides network status information to the source side, making the source-side to determine the correct state of network congestion. The simulation results show, RTP / RCU feedback information can better distinguish the congestion situation and the error packet loss, making rate control and error control efficiency has been greatly improved.
