摘　　要：针对多媒体应用中快速存储资源相对匮乏和磁盘速度受限问题 ,实现了使用网络空闲内存资源作为快速设备缓冲媒体的机制 ,扩展了多媒体环境中的存储层次 ,并给出了一种简单快速的 cache替换算法 .初步结果表明 。With the widespread of multimedia applications, data storage method becomes a challenging problem because of limited memory and disk bound. In this paper, we point out the benefit of network memory over magnetic disk, present the design and implementation of using network memory as a faster than disk device. It extends the memory hierarchies of computer by introducing a remote memory layer. And also we give a new cache replacement algorithm.As a result of experiment,it can speed up the access of data in multimedia environment.
