支持流媒体传输的模糊PID速率控制器
Fuzzy PID rate controller for supporting streaming media traffic
摘要
Abstract
There exist severe uncertainties in network transmission due to randomness of the network load variants,time-varying characteristics of round trip time（RTT）,which seriously affect the quality of service of streaming media.A fuzzy PID rate controller is proposed to support best-effort of streaming media based on fuzzy set theory,which efficiently compensates the time-varying uncertainties and enhances the stability and robustness of the closed loop systems,and realizes maximum bandwidth utilization.Fuzzy PID rate controller can calculate the desired sending rates of the controlled sources according to the router＇s queues,which makes the router＇s queue attain the set point,so the congestion of the router is avoided.Simulation results show that the fuzzy PID rate controller can efficiently deal with the time-varying characteristics and the fluctuation of the sending rates,which can guarantee the quality of service of streaming media.关键词
