An simulated analysis of maximal matching based on input-queuing

Focused on the lower matching scores of input and output port in every time slot based on input-queuing the maximal matching of router,the proposal is that by changing the methods to update polling pointer so as to improve the number of port matching,solve the synchronization problems on output port,and effectively optimize throughput rate of system.The simulation experiment showed that using matching of polling pointer was able to effectively optimize the performance of switches.
