ABSTRACT:
The invention switches and forwards information data packets when a plurality of the packets having the same address are competing for simultaneous attention. A plurality of sorting circuits are coupled in a hierarchial cascade. All competing packets are originally received by a superior circuit in the hierarchial cascade. It processes the packet which wins a competition for its attention and passes the rest of the non-winning packets down the hierarchial cascade for processing by an inferior circuit.
