The present invention relates to an AAL switch for multicast and a switching method for performing a flexible multicast connection. An AAL2 switch for multicast and a switching method for performing a flexible multicast connection can be used in applications like video conference and video on demand. An AAL2 switch can include a plurality of receiver circuits that convert an AAL2 packet into a CPS packet by demultiplexing, a plurality of storing devices that store a CPS packet separated from the AAL2 packet, and a plurality of transmitter circuits that periodically search the plurality of storing device and convert the searched CPS packet into an outgoing AAL2 packet by multiplexing. The transmitter circuits can transmit the outgoing AAL2 packet.
