Summary: 
This paper proposes a new multistage switch architecture for large-scale multicast ATM switching. The proposed architecture uses routing schemes both at the connection level and the cell level. This results in the reduction of the memory capacity required in the trunk number translators of the copy network modules. If Connection Splitting algorithm is used, a nonblocking switch can be constructed under the same nonblocking condition as that of point-to-point Clos network. It is shown that the memory requirements in the new switching network are less than the previous architectures.
