Abstract:
1. An interconnection network for routing data packets comprising: eight switching circuits capable of transferring data packets with each other; eight sequential data links bidirectionally coupling said eight switching circuits in sequence to thereby form an octagonal ring configuration; and only four crossing data links, wherein a first crossing data link bidirectionally couples a first switching circuit to a fifth switching circuit, a second crossing data link bidirectionally couples a second switching circuit to a sixth switching circuit, a third crossing data link bidirectionally couples a third switching circuit to a seventh switching circuit, and a fourth crossing data link bidirectionally couples a fourth switching circuit to an eighth switching circuit, wherein said first switching circuit has switch address wherein each of said eight switching circuits is associated with a processing node capable of processing said data packets, wherein a selected one of said eight switching circuits having switch address S(i) transfers a received data packet to a next sequential one of said eight switching circuits having switch address S(i+1) (modulo 8) if a destination switch address associated with said received data packet exceeds said switch address S(i) of said selected switching circuit by no more than 2.
