The multicast ATM switch has been developed for the purpose of the point-to-multipoint cell transmission. The basic structure of conventional multicast ATM switches is mainly based on a T.T. Lee's multicast switch, since it has a very simple and expandable structure. However, in spite of these benefits, it requires excessive hardware for the loss-free cell transmission, since it employs the blocking network, i.e., the banyan network as a copy network and a routing network. In this paper, we propose a new network for the multicast ATM switching. In proposed copy network, we adopt a new structure, the parallel broadcast banyan network with bypass links between switch planes, to offer the maximum cell transmission capacity and the fault tolerance. All conflict cells, which are blocked during the cell routing process, are bypassed to the next switch plane through bypass links and try to be routed. And to support the highly efficient cell transmission, we propose Alternate Path Scheme (APS) and copy-number (CN) comparator in the proposed copy network. APS is a kind of cell transmission schemes and guarantees multicasting capability to achieve a high performance. To estimate the performance of a proposed copy network, we provide several simulation results.
