本文对采用光纤通信道的面向终端的计算机网络的总体设计,从体系结构、通信物理媒质及调制技术、网络布局及信息送取方法、通信协议等方面作了描述.系统以光纤作通信传输媒质,用CAMAC型串行系统组成环行网,建立CAMAC通信协议,从而简便地实现了系统的构成,达到资源共享、信息流通量大、响应时间快的目的,且具有较强的容错能力.本系统经过一年多的试验,证明性能可靠,使用灵活,达到了设计要求.
This paper describes the overall design of the terminal-oriented computer network using optical fiber communication channel from the aspects of architecture, communication physical media and modulation technology, network layout and information acquisition method, communication protocol, etc. The system uses optical fiber as the communication transmission medium , A CAMAC serial system is used to form a ring network and a CAMAC communication protocol is set up so as to realize the system structure conveniently, achieve resource sharing, large information flow, fast response time and strong fault tolerance capability. After more than a year of testing, proven performance, flexible use, to meet the design requirements.
