摘要： 讨论多媒体文件服务器磁盘I/O带宽的分配策略问题，提出一种根据不同应用请求的负载变化情况对服务器磁盘带宽进行自适应分配的算法。该算法由负载检测模块、带宽管理模块组成，提高了多媒体文件服务器的易管理性，在短暂的过载情况下保持了服务器的稳定性，为更多的软实时请求提供服务。

关键词: 多媒体文件服务器, 自适带宽应分配, 尽力服务请求, 软实时请求

Abstract: This paper discusses the bandwidth allocation scheme in multimedia file server, puts forward a automatic bandwidth allocation scheme for different applications in single-disk. The bandwidth allocation techniques consist of two key components: a workload monitoring module that efficiently monitors the load in each application class, and a bandwidth manager module that uses these workload statistics to dynamically determine the allocation of each class. It raises the manageability of the multimedia file server and provides stable behavior even during transient overloads.

Key words: multimedia file server, dynamic bandwidth allocation, best-effort service, soft real-time request
