ABSTRACT:
A switch fabric for switching data traffic according to a plurality of links. The data traffic may convey audio information, video information, or any other type of information. The switch fabric includes input, output and at least one intermediate stages, each stage including a plurality of switching elements. The switching elements of the input and output stages respectively have external input and output ports. The switch fabric further includes a switch fabric controller. The switch fabric controller includes a link database including information about the plurality of links. The switch fabric controller is operative to search the link database to identify symmetrical links and to establish internal pathways between the input stage and the output stage through the at least one intermediate stage, wherein at least two symmetrical links identified by the searching are realized using a common switching element of the at least one intermediate stage.
