【摘要】 本文介绍了一种适于舰用的计算机局部网络通信协议。该协议主要实现ISO/OSI七层协议模型中的低四层协议,并且满足IEEE 802.4局部网络协议标准。详细介绍了实现协议所采用的VLSI技术的硬件设计和与之相配合的软件设计。同时,对其中的关键技术如:逻辑环的建立和维护、信息的优先级发送及实时响应和数据缓冲区的结构、管理作了重点说明。更多还原

【Abstract】 This paper introduces a kind of Local Area Network(LAN)protocoI suitable for warship environment. This protocol mainly includes the four layers of the ISO/OSI Reference Model, and which is compatible with the IEEE 802,4 LAN standard. The design of the hardware that used the VLSI technique and the software are introduced in details. Meanwhile, the main technique used in the design, such as setting up and maintenance of the logical ring, priority accessing to the network, real time respond, the data buffer structure and management are discribed.更多还原
