IEEEl394是一种具有支持等时传输和异步传输的特点的高速串行数据总线,目前已在航天器载荷试验数据传输中得到良好应用,但在未来大型空间飞行器载荷试验信息传输的应用中仍存在重量功耗开销大、传输距离和速率有限等问题。光纤通道作为一种具有良好兼容性、可靠性高、低时延、传输距离远和传输速率高等优点的先进总线技术,可为上层协议提供通用的高速率数据传输通道。基于IEEEl394和光纤通道的基本特性,给出了一种适用于空间载荷试验信息系统的FC-1394桥接方案,并为基于IEEE1394和光纤通道协议映射的空间信息系统数据网络互连提供了一种解决方案。
IEEEl394 is a kind of high-speed serial data bus which has the characteristics of supporting isochronous transmission and asynchronous transmission and has been well applied in the data transmission of spacecraft payload test at present, however, it still exists in the application of information transmission of large-scale spacecraft payload test in the future Heavy power consumption overhead, limited transmission distance and speed and other issues. As an advanced bus technology with good compatibility, high reliability, low latency, long transmission distance and high transmission rate, Fiber Channel provides a common high-speed data transmission channel for upper layer protocols. Based on the basic characteristics of IEEE1394 and Fiber Channel, a FC-1394 bridging scheme suitable for space load test information system is presented and provides a solution to the interconnection of spatial information system data network based on IEEE1394 and Fiber Channel protocol mapping Program.
