An interconnect topology providing enhanced fault tolerance to a multi-component data processing system. The topology utilizes a plurality of rings for interconnecting multiple system components, or cards, at least two of which are indirectly connected so that communication therebetween is through a third component. Each of the system components is coupled to a set of at least two different rings and includes interface circuits for routing data and a bridge for permitting data to be transferred between the at least two rings.
