Abstract:
1. A method for generating a train packet in an ATM switch system, comprising: a first scheduling step for selecting a service queue for various traffic type classified according to a number of destination ports of inputted cells and properties thereof as a service queue; and a second scheduling step for reading a unicast cell required to generate the train packet from a unicast queue corresponding to the multicast queue when the first scheduling step selects multicast queue to serve, and generating the train packet including effective cells, when the train packet is not generated with a multicast cell of the selected multicast queue, wherein the second scheduling step further comprises: the first step for reading the necessary unicast cell from the unicast queue identifying the 3 a second step for reading the unicast cell from the unicast queue corresponding to the multicast queue, and sequentially generating effective L0 train packets as many as switch planes, when the L0 train packets are not generated as many as the switch planes by using the multicast queue.
