Abstract：With the increasing of industry demand, the concept of network switch which with priority virtual output team was put forward, the scheduling policies of the switch which have virtual output queue become main factors of . In traditional VoQ switches, there is no distinction between the priorities of different businesses, all business priorities are equal, and the internal is only forward based on the advanced working mode. And with the gradually development of network, the traditional VoQ switch is not able to meet certain industries, such as aerospace, complex for high-speed data transmission network computing, distinguish between different business priorities, buA research of virtual output queue scheduling strategy with priority in FC switchsiness take different scheduling policies of different priority requirements. Based on the traditional VoQ switch queue model, this paper puts forward a new type of queue organization and cache scheduling strategy. The problem of head blocking between different priority packets was solved, and a simulation experiment platform was designed using OPNET to verify the feasibility and effectiveness of the scheduling strategy.
