摘要： 随着微机局部网络(LAN)产品的不断增加,LAN的体系结构,尤其是其高层结构的标准化已提到的议事日程上。本文的前半部分,提出了一个个人计算机局部网络体系结构的五层模型,并定义了各层的功能及相邻层之间的接口关系。后半部分介绍了一个基于该模型设计实现的个人计算机分布式网络操作系统。

Abstract: Along with the increase of microcomputer Local Area Network (LAN) products, the standardization in the architecture of LAN, especially in high layers, is under investigation. A fivelayer-model of personal computer LAN architecture is proposed in the first part. The functions within each layer and interfaces between adjacent layers are well defined. The second half describes the design and implementation of a distributed network operating system (PC-DNOS) based on the model.
