Design of a multicast packet switch architecture for ATM networks

The paper presents the design and performance evaluation of an ATM switch with multicasting capability. It consists of an input network, a copy network and an output network. The copy network consists of three non-blocking networks and two shared-memory buffers which pressure cell sequencing. It has an overflow controller which controls overflow of cells in the copy network and allows partial cell expansion. The architecture uses fully distributed control and thereby scales well to large size switches.<>
