分布式计算机网络DSA 是HONEYWELL公司1982年推向世界市场的。我们认为:DSA网络完全符合国际标准化组织ISO定义的七层协议参考模式。其软件本身是模块化的。需要什么功能就加载什么软件模块。DSA网络结构分为主网和次级网:在主网上可运行DPS系列机,在次级网上可运行各种终端,微机,局部网和异种大、中、小型计算机<如IBM计算机>。DSA网络还可与多种公共数据网相连。
Distributed Computer Network DSA is HONEYWELL company in 1982 to the world market. We think: The DSA network fully complies with the seven-layer protocol reference model defined by the International Organization for Standardization ISO. The software itself is modular. What function is needed to load what software module. DSA network structure is divided into the main network and the secondary network: In the main network can run DPS series machines, in the secondary network can run a variety of terminals, computers, local area networks and heterogeneous large, medium and small computers such as IBM computers. DSA networks can also be connected to a variety of public data networks.
