Abstract
An input distribution packet switch network includes a plurality of 2×2 switch elements and packet input modules for the switch network. The switch elements are arranged in multistage and connected in accordance with Shuffle type topology to constitute a N×N switch network (N=2 , k: integer number of 2 and over). The links of the leftmost and rightmost switch elements are connected to one another so that the N×N switch network can have a ring architecture. The packet input modules are distributed laterally in the switch network.
