Abstract
A high data rate switch is disclosed. The switch may include fiber optic channels where a plurality of switching elements necessarily operate at a significantly lower data rate providing routing of variable or fixed size data packets from a plurality of source ports to a plurality of destination ports via a single serial link. This is may be provided by storing the high rate data temporarily in memory in each of the source ports and then downloading it at a lower rate in a complete data packet to a designated switching element, almost immediately distributing the next data packet that has been received by the source port to a next switching element. The switching element configuration provides automatic redundancy and a minimum amount of frame overhead while sustaining throughput at the high data rate.
