A Distribution Technology Based on Segmentation Prefetching and Pipelining in Classified Streaming Media Service

A proxy server is presented and divides the streaming media service that users access to in the 3G network into different types. According to the characteristics of service types, the proxy server uses different segmentation prefetching to improve the efficiency. Meanwhile, this paper introduces the assembly line technology which improves the speed of the streaming media distribution, effectively utilizes bandwidth and increases the throughput of the proxy server. The simulation results show that using a variety rational of segmentation prefetching algorithms and efficient pipeline distribution can reduce the bandwidth consumptions of the proxy server and the 3G network. Furthermore, the proxy server offers a better quality of service to the users.
