Abstract
A switch for switching traffic from N sources to M destinations, where M and N are each an integer greater than or equal to 2. The switch includes K segments, where K is greater than or equal to 2 and is an integer. Each segment receiving traffic from R of the N sources, where 1≦R<N and is an integer, and all K segments in total receiving traffic from the N sources. Each segment collecting and queuing traffic from the respective R sources. The switch includes an arbitrator which receives information from the destinations regarding if they can receive data or not, and from the K segments about the traffic they have for different destinations. A method for switching traffic from N sources to M destinations, where M and N are each an integer greater than or equal to 2. The method includes the steps of receiving traffic from the N sources at input ports of K segments, where K is greater than or equal to 2 and is an integer. Each segment receiving traffic from R of the N sources where 1≦R<N and is an integer. Then there is the step of sending traffic from any segment to a destination through an output port of an arbitrator which connects to each segment. An arbitrator. A segment.
