光总线系统网络拓扑结构的可靠性分析

光总线精确制导控制与测试系统具有技术难度大、系统性强、所处环境恶劣,电磁兼容性要求高的特点.要有效地保障系统预定任务的顺利执行和完成,提高战斗出勤率,因此,IEEE-1394b 光总线系统必须是高可靠的、高稳定的.分析研究IEEE-1394b光总线拓扑的可靠性实验研究,是解决IEEE-1394b 光总线系统可靠性问题的重要内容之一.提出了基于IEEE-1394b 协议的光总线网络拓扑结构的可靠性研究方案,建立了环状拓扑可靠性分析模型,并给出了示例分析.实验结果表明,这种环状拓扑结构具有高的可靠性.

Reliability analysis of network topology in optical bus system

The accuracy guidance weapon''s control and test system with optical bus have the character of technical difficulties, systemic strong, in a poor environment and high electromagnetic compatibility. To effectively protect the system which is scheduled for the implementation and completion of tasks smoothly and to improve the fighting attendance, therefore, IEEE-1394b optical bus system must be highly reliable, high-stability. The reliability analysis of IEEE-1394b optical bus topology is an important part of the problem to solve the reliability of IEEE-1394b optical bus system. This paper presents the reliability of research programs of network topology based on IEEE-1394b protocol optical bus, establishes the reliability analysis model for ring topology and gives a case study. The experimental results show that the ring topology has high reliability.
