Abstract
A network of switches having a first switch having a first memory interface and a first expansion port. The network also has an expansion bus having a first expansion bus interface and a second expansion bus interface. The first expansion bus interface is connected to the first expansion port. A second switch has a second memory interface and a second expansion port. The second expansion port is connected to the second expansion bus interface, thereby connecting the first switch to the second switch, wherein the expansion bus allows the first switch to directly access the second memory interface through the second switch and the second switch to directly access the first memory interface through the first switch.
