ABSTRACT:
In a one-sided crosspoint switch, multiple controllers are used instead of a single controller for control of the switching matrix. The controllers operate in parallel, thereby handling requests for connections and disconnections from ports at a higher speed than with a single controller. In the event of a controller failure, the remaining controllers also take over the control function of the failed controller, thereby providing improved reliability.
