针对高速光纤交换网络高质量的交换服务需求,提出了一种适用于信令寻径式高速光纤通道交换机的信令降频方法.该方法采用一套特殊的序列码对信令帧内容进行编码后传输,以达到信令帧信号频率成倍降低的目的,使交换机无需借助串并转换器对高频信令帧进行降频,就能够直接识别信令帧内容.试验结果显示,采用信令降频方法后,交换机的结构显著简化,可靠性得到很大提高,并且硬件成本大大降低.

In order to acquire high speed switching in high-speed fibre channel switch network,a method applying to the token-routing fibre channel switch to reduce the token's frequency was put up.In this scheme, the token is coded with "the reducing-frequency code",that is a special sequence of '0' and 'l',then it's frequency may be reduced multiply, and the switch can extract the information of token without the serial-to-parallel converter.The results show that the structure of switch is simplified while its reliability is greatly improved and its costs is significantly decreased.
