目前,代理缓存技术广泛应用于改善流媒体传输的服务质量.文章从实际用户日志文件的分析出发,利用发现的用户浏览流媒体对象时的行为分布模型,提出了一种新的视频流媒体缓存算法.仿真结果证明,该算法可以通过记录很少的用户访问信息获取较高的性能表现.
Proxy caching is widely used to improve the quality of streaming media transmission. This paper proposed a new proxy caching algorithm based on the distribution of user access preference in streaming media. The simulation results show that this algorithm has similar performance compare with other segment based caching but it requires significantly less state information.
