摘要
当前机动平台上广泛使用的1553B协议越来越不适应数据传输的需求增长,需要找到一个1553B协议在光纤通道上实现的方法,以获得光纤通道所具有的优势性能;1553B协议原设计实行在线缆上,因此就必须实现其到光纤通道的转换接口;1553B协议使用的是命令/响应模式,并以消息、字为传输单位,而光纤通道则是以交换、序列、帧为传输单位,对两者传输单位的映射和传输机制进行设计,完成1553B协议在光纤通道上的实现;最终通过测试验证了设计的正确性,经过转换的协议可以支持原有协议的功能,并且在性能上达到光纤通道提供的传输速率。
As the data to be transmitted increases rapidly, the traditional 1558B protocol widely used in present mobile platform is no longer able to meet the demands, which requires implementing the 1553B protocol on fibre channel in order to take advantage of its great performance. To transplant the implementation of the 1553B protocol from cable on which the protocol is original designed, to fibre channel of high speed and high reliability, it is necessary to design and carry out an interface to adapt the 1553B protocol to fibre channel. The 1553B protocol adopts the Command/Response pattern and uses message and word as the data transmission unit, while in fibre channel data is transmitted in sequences and frames. And this paper presents the solution of mapping the corresponding data transmission units between them and designing the mechanism of data transmission, as well as the final implementation of the 1553B protocol on fibre channel.
