The Research of a Method of Reducing the Token´s Frequency in the High-Speed Fiber Switch Network

In order to acquire high speed switching in high-speed fiber channel switch network, a method named MRTF (the method of reducing the token´s frequency) used to reduce the token´s frequency is put up, and the corresponding switch is designed. In this method MRTF, the token is coded with RTFC, the token reducing-frequency code which is a special sequence of `0´ and `1´ , then it´s frequency may be reduced multiplied, and the switch can extract the information of token without the conversion between the serial signal and the parallel signal. The results show that the structure of the switch is simplified while its reliability is greatly improved and its cost is significantly lowered.
