Benes switching fabrics with O(N)-complexity internal backpressure.

Multistage buffered switching fabrics are the most efficient method for scaling packet switches to very large numbers of ports. The Benes network is the lowest-cost switching fabric known to yield operation free of internal blocking. Backpressure inside a switching fabric can limit the use of expens...
