“…Systemlevel supports for these new appliances are important to provide different types of services and user interactivities. One of the most important systemlevel supports is the deployment of caching mechanisms in multimedia streaming servers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. An efficient caching mechanism in the multimedia environment can reduce the service latency as well as allow more streams to be admitted by obviating the need for disk I/O.…”

With the prevalence of video-on-demand (VOD) services as well as the diffusion of various multimedia devices, caching in a multimedia streaming server is becoming increasingly important. However, due to some peculiar characteristics of multimedia objects and user activities in streaming services, design of an efficient caching system becomes a more challenging problem compared to the traditional caching systems. This paper discusses some important issues that are of interest in the domain of multimedia streaming caching and presents a new cache management scheme for multimedia streaming servers. Our new scheme considers different streaming rates of multimedia objects as well as the inter-arrival time between two consecutive requests on an identical object. It also considers user activities in requesting and playing multimedia contents. Trace-driven simulations with real world VOD traces show that the proposed scheme improves the performance of multimedia streaming systems significantly.
