Interconnection networks based on a torus or k-ary
n-cube topology are widely used as switch and router fabrics (Avici TSR), processor
memory interconnect, and I/O interconnect (InfiniBand).
In many of these applications, it is essential that the interconnection network guarantee a minimal throughput regardless of the traffic
pattern. In an internet router, for example, there is no backpressure on input channels
so the interconnection network used for the router fabric must handle any traffic pattern at line rate or packets will be
dropped. At the same time, an efficient interconnection network should exploit locality to achieve
high performance and low power on local traffic patterns.
