Study on VOD server performance and service patterns

The key challenge in VOD domain is to provide interactive services in thousands of potential users at a reasonable cost. In order to address this problem, a deep study on VOD server performance and service patterns is carried out. Firstly, severalcategorizations in VOD systems are introduced. Then a deep and abroad analysis about the critical elements which effect the performance of a VOD server greatly as well as several service patterns that can be applied to the system is presented. Based on the analysis, some practical strategies and techniques that can improve the VOD server's performance and the quality of service the system provides are proposed and discussed.
