Abstract: Recently, there are many difficulties in stream media transmission over the Internet, because massive media files transmission needs high bandwidth, and if there is no corresponding conditions in Internet, it may lead to throw the packages and network delay, which can reduce the quality of stream media. This paper introduces a stream media high quality transmission strategy, which can reduce the package of frequency and guarantee reliable stream media transmission by mistake check and congestion control.

Key words: P2P overlay network, stream media transmission, mistake check, congestion control

摘要： 目前，在Internet上传输流媒体还存在许多困难，因为大量的媒体文件传输要求较高的带宽，所以在网络环境无法满足的情况下，容易造成丢包和延迟现象，降低流媒体的传输质量。该文提出了一个流媒体高质量传输策略，从质量控制的差错控制与拥塞控制两方面来降低丢包率，保证可靠的流媒体传输。
