Abstract: In order to acquire high communication performance in high-speed fibre channel switch network, the high-speed fibre channel switch protocol based on reducing the token's frequency,named as FCSP-RTF,was put up. On the basis of the token-routing technology,FCSP-RTF codes the token frames with the reducing-frequency code, so the switch can extract the information of token without the serial-to-parallel converter, and fulfill the work of switch quickly and correctly; and FCSP-RTF also simplifies its frames, so that the higher communication efficiency is achieved. The resups show that the structure of the FCSP-RTF frame is simple and the implementing of FSP-RTF is easy, and the communication performance and the reliability of the fibre channel switch network arc greatly improved while it's costs are significantly lowered.
