集成多媒体文件系统模型研究

目前的文件系统大多是单一类型的文件系统，或者采用尽力服务策略优化文本文件的服务，或者采用资源预留策略优化连续媒体的实时服务，而不能同时满足不同服务类型访问不同类型数据的需要。随着计算机计算能力、存储部件性价比的提高，以及计算机网络的不断发展，应用系统越来越大、越来越复杂，需要同时包含不同的应用类型和同时访问不同类型的数据。文中通过分析典型的应用类型和数据类型的特点，归纳出集成多媒体文件系统应具备的功能，并提出了实现集成多媒体文件系统的层次模型。

A Layer Model for Integrated Multimedia File System

The existing file systems are single class file systems which either provide a best-effort sehoce for textual data or employ resomee reservation algorithms for real-time service of continuous media,but can't meet the needs of simultaneously supporting different server classes and different data classes. With the increasing of computer power,rate of storage performance/price and the developing of computer network,the application systems are becoming more and more large and complexity,which need to suppori different server classes and different data classes. By analyzing typical server classes and data classes,this paper concludes the fonctions that the integnted multimedia file system must have,and put forward a layer model for integrated multimedia file system.
