摘要: 针对先进航空电子系统对数据网络的高速和混合通信的需求,基于分布式控制、实时存取和故障容忍的设计思想,进行了分布式光纤网络的结构设计和协议选择.重点分析了光纤链路、介质访问控制协议、拓扑、容错技术和网络管理软件.分析结果表明,基于1394b总线的分布式容错光纤网络能提供确定和可靠的通信,同时该吉比特光纤链路满足误码率要求且功率余量达13dB.因此它是具有高带宽、低延迟和易扩展优势的高综合网络结构.

Abstract: In advanced avionics systems, the date communication system requires high speed and hybrid traffic. A scheme of distributed fiber-optic network system was presented based on the design consideration of distributed control, real-time access and fault-tolerance. Along with designing the architecture and choosing the protocol, the critical technology points of the scheme were analyzed emphatically, including fiber-optic links, media access control(MAC) protocol, fault- tolerance, topology technology and network management software. The analysis result indicates that the distributed fiber-optic network based on IEEE 1394b bus can provide deterministic and reliable communication in which the Gb/s fiber-optic link can meet the necessary of bit error rate (BER) with abundant link margin of 13dB. Therefore it has advantages of high bandwidth, low delay and flexible expandability.
