Abstract


In this paper, high-speed routers in a switched network scheduling algorithm is studied , including those based on the structure of the input queuing crossbar scheduling algorithm based on load balancing and two switch fabric scheduling algorithm. Paper introduces the high-speed router switch fabric and development overview and then describes the crossbar structure based on the latest input queuing scheduling algorithm, output queuing scheduling algorithm and joint input and output scheduling algorithm. Which based on maximum matching input queuing scheduling algorithm has good performance , focusing on analysis of several maximal matching scheduling algorithm PIM, RRM, iSLIP algorithm, using queuing theory analyzes the performance of adding priority algorithm , and on this basis proposed anti- burst and non-uniform business lp_iSLIP, op_iSLIP and OSRR algorithms. The two exchanged on the load balancing algorithm is analyzed theoretically proved that the algorithm stability and delay , the classical algorithm has been improved UFS program . Finally, the simulation results show that the proposed algorithm performance of several significant improvements .
