Yicai Li · Journal of Sichuan University · 2007
Based on technology of PFTS,this paper introduces a new scheduling algorithm based on buffered switch fabric,which could be implemented in PFTS nodes to fit the requirement of fast data switching and QoS (quality of service) guarantee in SUPANET(single physical layer user-data platform architecture network).By adding one EPF frame buffer in each cross-point of switch fabric,this new algorithm adopts Round Robin scheduling algorithm in each input port and each output port separately and independently and makes traditional integrated and complicated CIOQ algorithm simpler.Simulation results have shown that the new scheduling algorithm has advantages among effectiveness,scalability and complexity and is most suitable for future high-speed PFTS nodes in SUPANET
