光纤通道在基于MIL-STD-1553的航空电子系统网络中的应用

光纤通道作为新一代的航空电子系统通信网络技术,具有传输速度高、延时低、传输距离远和可靠性高等特性,高达4G bps的数据传输带宽,为其上层通信协议提供了一种通用的高速率的数据传输通道。FC-1553作为光纤通道上层通信协议之一,对MIL-STD-1553通信协议具有完全的兼容性,它继承了传统MIL-STD-1553通信协议的基本特征,实现了向光纤通道链路层的映射,从而扩展了通信网络的结构,提高了网络的通信能力。本文首先介绍MIL-STD-1553和光纤通道的基本特性,然后描述在光纤通道中对1553通信协议的映射,最后,提出了基于光纤通道和MIL-STD-1553的航空电子系统通信网络结构。

The Application of Fibre Channel to MIL-STD-1553 Based Avionics System Networks

Fibre channel,as one of the candidates for the next generation avionics system networks,has features,such as high transmission rate,low time delay,long transmission distance,and high relia-bility.It provides a high-rate data transmission channel to high-level communication protocols.Its highest bit rate can be up to 4Gbps.FC-1553,a fiber channel protocol,is compatible with MIL-STD-1553,and,by inheriting the basic characteristics of MIL-STD-1553 based systems,implements the map of MIL-STD-1553 on fibre channels.So the scale of the networks will be expanded in structure and data transmission.This paper,first of all,presents MIL-STD-1553 and the basic characteristics of fiber channel,and then describes the data frame mapping from MIL-STD-1553 to fiber channel.Finally,an application of fiber channel network,which is based on legacy MIL-STD-1553 systems,is given.
