SIMULATION MODELING OF MULTICAST IN ATM SWITCH

It has been proved that center buffer based ATM switch offers better performance under conditions of identical memory size. Here described in detail are the approach to multicast cells and the way to solve the collision between multicast and unicast in switching system. A new solution to multicasting cells called single write and single read with output buffer and output mask, is put forward,thus avoiding cell loss, and reducing cell delay. Finally, the way to setup a model of simulation is also given
