企业网的组成技术

Enterprise Network's Component Techniques

企业网是一种涉及局域网、广域网、分布式计算等多方面技术的网络。对这一问题的研究应从企业网的组成技术、共性与特性、一般性原理与具体实现等方面进行。在这样一个总体框架的指导下，才能比较全面的认识目前企业网技术的发展方向和主流。在本文中，侧重于从组成技术方面对工业自动化领域企业网涉及的计算机通信网络、网络管理与安全及分布式计算等作一概要的分析。

Enterprise network in industrial automation consists ofLAN, WAN,Field Bus, and distributed computing etc.. Along withthe development of network technology, Enterprise network will be abackbone based high-speed information network, supportingdistributed multimedia application . As it is a complicated system, itsresearch should be done from three aspects, which are componenttechniques, common and special attributes, general principals andspecific implementations. Under this framework, we have discussedits component techniques of computer communication network,network management and security and distributed computing. Andsome issues for future research are also presented.
