摘要
为方便流媒体传输算法的研究,文中提出了利用流量模拟器对网络流量进行控制和调节的方法,从而在实验室内建立一个能够模拟互联网传输参数的实验环境.影响流媒体传输的主要参数为带宽、延时、延时抖动和丢包率,流量模拟器主要对丢包率、延时和带宽等参数进行控制和调节.在模拟实验中,模拟的输出参数基本同预设参数一致,验证了模拟器的可行性.
In order to explore the algorithms of transmission of the streaming media,the stream simulator is proposed to control the stream of the network.The key parameters of the transmission of streaming media are bandwidth,delay,the jitter of the delay and the rate of packet loss,therefore the stream controller mainly controls packet_less ratio,delay and bandwidth.If the parameters of the simulator are consistent with those of the stream of the real network,the algorithms of the transmission of streaming media is proved feasibile.
