It has been shown that input queued (IQ) switches have throughput limitations when loaded with multicast traffic. However, if circulation of packets is allowed, the IQ switches can be non-blocking for any admissible multicast traffic scenario using only a speedup of two. The non-blocking frame based algorithm for scheduling the multicast traffic is proposed.
