摘要
实现UDP和TCP数据流的公平性以及在UDP中解决拥塞控制从而保证传输可靠性是提高服务质量所面临的两个迫切需要解决的问题。提出一种解决上述两个问题的方案——FFUDP(Friend and Fair UDP),即UDP根据丢包率来判断网络的拥塞情况,如果网络拥塞,接收方通知发送方调整发送速率从而有效解决公平性问题以及UDP的拥塞控制问题。仿真结果表明,FFUDP大幅度提高了数据吞吐量,降低了丢包率,实现了与TCP数据流的公平性。
The quality of service is confronted with two challenges. One is how to achieve the fairness of TCP and UDP, and the other is how to solve the congestion control in order to improve the transmission reliability. This paper presents a solution FFUDP （Friend and Fair UDP） to address the two problems. FFUPD determines the network congestion state based on the packet loss rate. If the network congestion is detected, then the receiver notifies the sender of adjusting the transmission rate to effectively address the fairness and UDP congestion control. The simulation results show that FFUDP substantial increases the throughput and reduces the packet loss rate, and moreover the fairness of FFUDP and TCP is achieved.
