本文对各种可能应用于局部综合业务网的拓扑结构和控制方式进行了研究和比较。论证了总线形结构的若干优于其它拓扑结构的特点。讨论了几种用于总线网的控制方式,证明了单向传输规程Fasnet所需控制信息量为最小。并详细介绍了作者采用Fasnet规程所作的网络接口软、硬件以及在三个终端(电话、微机)之间的通信实验。 This paper studies and compares various topologies and control methods that may be applied to the local integrated services network. Several features of the bus structure are demonstrated that are superior to other topologies. Several kinds of control methods for bus network are discussed, which proves that the amount of control information required for one-way transmission protocol Fasnet is the minimum. The author introduces the network interface software, hardware and the communication experiment between three terminals (telephone, microcomputer) by Fasnet protocol in detail.
