摘　　要：针对中小型企业数据处理的特点,提出了一种基于局域网的分布式内存管理系统,介绍了系统的数据组织方式、设计原理和各功能实体的具体实现。系统利用局域网内存资源存储数据,解决了磁盘输入/输出的性能瓶颈问题。把数据分成包,通过包管理实体对内存资源进行管理,利用同步协议机制保持主包和备包的同步。测试结果表明,利用系统对数据进行处理的效率是本机硬盘的5到7倍。According to the characteristics of data processing in the middle-small enterprises, a distributed memory management system based on LAN is proposed. The manner of data organizing, the design principle and the concrete implementation of every fu~,ction entity in the system are introduced. The system uses the memory resource in the LAN to store data. solves the problem about I/O capability bottleneck. The data is divided into packages, and the package management entity is used for the management of memory resource. Main package and backup package are kept synchronization by synchronous protocol mechanism. The results of test show that the efficiency of data processing by using the system is 5 to 7 times as high as that by using the local fixed disk.
