The present, there are growing demands for video streaming which are likely to increase as the users can easily access the Internet. Video file data is usually large and continuously sorted. It requires a lot of resources to process and communicate data between clients and the server. Cache is used to increase the efficiency and to reduce the time to read data from the storage which has a slow reading rate. This thesis introduces a cache system that exploits the video file popularity in the cache replacement policy in order to increase the efficiency of the cache system that serves video files via HTTP streaming, and also add the popularity attenuation process that decrease the popularity as the time passes by. It helps increase the cache efficiency by increasing the cache hit rate, reducing the latency of data retrieval from the backend storage, and as a result for reducing the process time for transmit from the HTTP server to the client.
