Video Proxy Server Management Policy using Virtual Caching Technique

Due to the limited storage space in video proxy server, it is often required to replace the old video data which is not serviced for a long time with the newly requested video. This replacement causes the service delay and increase of network traffic. To circumvent this problem, we present a virtual caching technique for an efficient video streaming service in video proxy server. For this purpose, we employ a virtual memory. The requested video segment is not residing in the proxy server in first loaded in the virtual memory. The video in the virtual memory is stored in the proxy server depending on the consuming pattern by users. In addition, we propose an efficient replacement scheme in a proxy server. The simulation results show that the proposed algorithm performs better than other algorithms in terms of packet hit rate and number of packet replacement.
