A fair and efficient multicast ATM switch based on deflection routing

In this paper we propose a deflection routing based N×N ATM multicast switch. The switch consists of a copy network, a routing network and a novel mechanism to reduce memory requirements. We analyze the switch performance and show that the switch requires only O(log N) stages for low packet loss rates. Our theoretical results are backed by simulations of the switch. The switch is output queued and allows the delivery of multiple packets to the same destination during a time slot
