A PS scheduling algorithm of stream media transmission
Yubo Tan, Zhou Dexing, Tao Yang · 2010
The transmission of stream media over the Internet require a high bandwidth. While the best-effort network could not provide constant transmission speed. The proxy server (PS) is the nearest part of the Internet to the client. The proxy can cache the data, and release the load of the servers. So the proxies have great influence on the video QoS. Through the perfect algorithm, within the acceptable scope, the proxy can improve the performance of the system. In this paper, a new cache replace strategy based on AFEC is proposed, Layered Coded Packets Based Object eXchang Strategy- LCPOXS, which can employee the characteristics of the proxy and can improve the system performance within the normal resource.
