Apparatus and method for configuring multicasting network in asynchronous transfer mode switching system

Abstract

The present invention relates to a multicasting network apparatus and method for an ATM switching system having a banyan network and a route network which includes a header encoder part for generating a header, a boolean splitter network for copying a cell routed from the banyan network to thereby transmit the same to a route network. The boolean splitter network includes a plurality of boolean splitters, each of the boolean splitters includes the step of dividing the destination addresses of a cell into an upper group and a lower group and selecting an active port to thereby route the same. As described above, any extra translation table is not required owing to a cell copying operation according to the present invention, whereby the number of hardware components can be reduced, and an expansion can be easily performed.
