Abstract: A new type of switching fabric architecture—MR (Magic Ring) is proposed. The fabric inherits good performance of the traditional three stage indirect interconnection network, and possesses good scalability due to the adoption of the ring network at its second stage, which solves the problem that the present switching fabrics cannot obtain both of the two characters simultaneously. The good performance and good scalability of this fabric are shown by theoretical and simulative analyse.

Key words: switching fabric, scalability, direct interconnection network, indirect interconnection network, MR network
