一种优化校园VOD系统性能的方案

摘要

Campus network video on demand system(VOD)is an important part of digital campus construction ,and it can make up for the shortage of traditional teaching methods and provide varieties of digital media services. A set of VOD system based on Java platform has been improved during the period of the research ,and some factors that influence the quality of service have also been found in the phase of operation and maintenance. So an optimized scheme of campus VOD system performance has been proposed and realized by experiment. The results show that the integration of Ubuntu and Helix can improve the efficiency of VOD system ,and the scheme can be generalized in practice.%校园网络视频点播（VOD）系统是数字校园建设的重要环节，可提供丰富的数字媒体服务，用以弥补传统教学手段的不足。在以前设计的基于Java的VOD系统的基础上，改进了一些影响服务质量的因素，提出了一种优化校园VOD系统性能的方案并进行实验。结果表明，Ubuntu整合Helix能提高VOD系统的运行效率，使用户有更加流畅的体验，且可推广至实际应用中。
