ABSTRACT:
A full access, non-blocking, self-routing packet switch based on a Batcher sorting network is disclosed. Fake place holding packets are utilized along with a conflict resolution scheme to insure that during each packet switch cycle a packet is routed from each input port to each output port. The use of fake place holding packets insures that real packets which contain user data can be routed to the outputs having the addresses contained in their packet headers.
