摘要
分析了流媒体业务在无线环境下传输所存在的问题,在TFRC算法研究的基础上,提出了一种适用于流媒体业务传输的无线TCP友好拥塞控制机制WL_TFRC,在接收端引入了丢包区分机制来区分拥塞丢包和无线丢包。
The existing problems of real time multimedia stream Transmission in the wireless network are discussed.In the basis of TFRC algorithm,a TCP-friendly congestion control mechanism based on the wired network named WL_TFRC is proposed.The difference of congestion losses and wireless losses leading to the drop of performances is distinguished by the differentiation drop of performances mechanism.
