【Abstract】 Recently many solutions have been proposed for realizing various ATM switching systems,such as the input buffer based,output buffer based,and center buffer based ATM switch systems.It has been proved that the center buffer based ATM switch has better performance under the identical memory size. This paper states the way to multicast cells and illustrates how to solve the collision between multicast and unicast in switching system.It provides a new solution for multicasting cells,avoiding cell loss,and reducing cell delay,which is called single write and single read with output buffer and output mask.Finally,it provides the way to setup a model of simulation.更多还原
