By recirculating the cells that did not make it to their output ports during the current time slot back to the input ports via a set of recirculation paths, 34 BASICS OF PACKET SWITCHING the cell loss rate can be reduced. This results in system throughput improvement. The disadvantage of recirculation switches is that they require a large switch to accommodate the recirculation ports. Also, recirculation may cause out-of-sequence errors. Some mechanisms are needed to preserve the cell sequencing among the cells in the same connection.
Because of output contention, however, cells destined for the same output may not be able to be delivered at the same time, and some of them may have to be buffered at inputs. We also assume that each input link and output link has the same transmission speed to connect to the outside of the switch, but the internal switch fabric can have a higher speed to improve the performance. In this case, each output may require a buffer also.
