3 COM 公司以太网是目前应用较广、评价较高的一种局部网络,但该网络没有汉字信息处理功能,站点之间的数据通信缺乏实时性。本文在详细分析以太网和初步实验的基础上,主要讨论了以太网二次开发的几个技术难题,指出了以太网络操作系统和网络系统软件汉化的几个关键点。在实现点对点实时通信时,采用网络板硬中断响应方式,利用并发进程调度算法基本解决了“第三方”插入问题。
However, the network does not have the function of Chinese character information processing, and the data communication between the stations lacks real-time performance. Based on a detailed analysis of Ethernet and preliminary experiments, this paper mainly discusses several technical problems of secondary development of Ethernet and points out several key points of the localization of Ethernet operating system and network system software. In the realization of point-to-point real-time communication, the network board hard interrupt response, the use of concurrent process scheduling algorithm basically solved the “third-party” insertion problem.
