Backplane configuration without common switch fabric

摘要

An electronic system for networking, switching or computing includes a backplane-based interconnection system (100). The system includes a backplane (102) with a plurality of traces coupled to slots for receiving circuit packs (104a-d). The backplane traces are configured to form point-to-point connections (106a-f) from one slot of the backplane to every other slot of the backplane. A hub circuit (110) is provided on each circuit pack for coupling the circuit pack to the point-to-point connections in the backplane. Circuit packs communicate via direct connections over the point-to-point connections or indirectly by sending traffic through point-to-point connections and hub circuits. <IMAGE>
