This paper proposes an out-of-sequence (OOS) preventative cell dispatching algorithm, the multicast flow-based round robin (MFRR), for multicast input-queued space-memory-memory (IQ-SMM) Clos-network architecture. Independently treating each incoming cell, such as the desynchronized static round robin (DSRR), can lead to cells of the same packet being disordered after traversing the switch fabric. Extra reassembly buffer and delay are thus required at the outputs of the switch fabric to reorder the cells. Simulation results obtained by OPNET Modeler show that the MFRR can eliminate such OOS problem by monitoring the changes of received fan-out vectors
