As the Internet grows exponentially, scalable high performance routers and switches on backbone are required to provide a large number of ports, higher throughput, lower delay latency and good reliability. At present, most of these routers and switches are implemented on single crossbar as the switched backplane fabric. But the complexity of the single crossbar is increased with O(N2 ) in terms of crosspoint number, which is unacceptable for scalability when N becomes large. A delta class self-routing multistage interconnection network with the complexity of O(Ntimeslog2N) has been widely used in the ATM switches. However, the reduction of the crosspoint number results in the serious internal blocking. To solve this problem, quite a few scalable methods have been proposed. One of them, more stages with recirculation architecture is used to reroute the deflected packets, which increase the latency a lot. In this paper, we first bring out the multiple-panel MIN switching fabrics with interleaved recirculation. We also show how to correctly choose the recirculation points to reroute the cells, compared with the wrong connections of former publication. From the simulation under different traffic patterns, this new interleaved architecture, which is insensitive to congestion, could achieve better performance than its counterpart of single panel fabric.
