The main problems of structure of industrial LAN are analysed. Among various structures, the Token Bus and Ring should be principal In the industry application at first, and the master/slave bus and the star structure should be secondary. Furthermore, two kinds of painting models of structure of the industrial LAN are introduced. A new concept of the control structure of the LAN is proposed primarily. And the concepts of effective and viewing bit length and bit length factor are proposed. By means of the bit length factor, the simple data throughput models of the Token Bus and Ring are derived. In most cases, the throughput performance of the Token Ring is higher than that of the Token Bus

本文分析了工业局部网络结构中的主要问题。认为令牌环和令牌总线是工业局部网的主流结构形式,主从式总线和星形结构是它的补充形式。本文初步提出了局部网络的控制结构概念,以及有效位长度,无效位长度、视在位长度、位长度因素等概念。利用位长度因素,本文推导了令牌总线和令牌环的简单吞吐性能模型。根据这个模型及其它工程评价,本文提出了工业局部网的两种参考结构模式,并认为模式二对我国国情更具吸引力。

A new concept of Lan, Control Constitution (CC), is advanced. The differences and relations between CC and MAC from IEEE 802 Standard are discussed. Control Constitution is a structure logically paralleled with Topological Structure, and their integration forms a new concept of LAN. Based on CC, a reference model for LAN structure analysis is proposed. Another new concept of LAN communication, Bit Length Series (BLS), is also advanced. It consists of Effective, Ineffective, Viewing Bit Length and Bit Length Factor. It builds the relations among the LAN performance parameters and the communication efficiency is indicated by BLS. As the application of these new concepts, an LAN performance analysis model is briefly introduced.

本文提出和定义了计算机局部网络的控制结构的基本概念。讨论了它与IEEE 802标准的MAC的区别和联系。认为控制结构和拓扑结构一起,组成了局部网络完整的结构概念,以此本文进一步提出了局部网络的结构分析参考模型,它建议了对局部网络结构进行考察、技术划分、评估的统一方法。 本文还提出和定义了局部网通信的位长度系列概念,包括有效位长度、无效位长度、视在位长度和位长度因素,该概念对通信过程进行了抽象和划分,建立了网络性能参数的普遍联系。其中位长度因素反映了通信效率的大小。 最后,本文略述了以上新概念的应用之一:建立网络性能分析模型。
