Abstract
A packet switching network that accommodates the appearance of multiple occurrences of packets addressed to the same destination are accommodated. The network includes a recirculating delay block within the switch, and an expander that includes a modest number of multiple appearances of the same address, followed by memories that accept the packets delivered at those multiple appearances, store the packets, and output the stored packets to the user, one at a time, in accordance with a set priority scheme.
