ABSTRACT:
A multi-stage switching network that can hitlessly reconfigure itself comprising a controller that controls each stage separately. The controller designates the paths through each stage according to the set of paths currently active. If the set of paths changes, the controller sends a new set of paths to the first stage while using the old set of paths for the second stage during a first frame. On the next frame, the controller causes both stages to use the new set of paths.
