由于微型和小型计算机越来越广泛的应用,计算机网的覆盖面积和覆盖密度正在与日俱增。鉴于我国通信资源贫乏,优先发展本地计算机网是适宜的,这样既可以摆脱暂时的困境,又可以获得计算机网建设和应用的经验。本文分析了本地计算机网的各种发展方法,把它们分成三类情况;(1)协议不变;(2)协议转换;(3)制定新协议。 Due to the increasingly widespread use of miniature and small computers, the coverage area and coverage density of computer networks are increasing. Given the paucity of communications resources in our country, it is appropriate to give priority to the development of a local computer network, so that we can get rid of temporary difficulties and gain experience in the construction and application of computer networks. This article analyzes various ways of local computer network development, and they are divided into three categories; (1) the same protocol; (2) protocol conversion; (3) the development of a new protocol.
