Abstract
A system having an I/O interconnect topology utilizes internal packetized communications. The system includes a host system element, a plurality of switching elements, and a root complex to bridge communications between the host system and the switching elements. The ports of at least some of the switching elements have a cross-link device associated therewith, which is a logical device defined by configuration space of the switching element. Each cross-link device defines a cross-link communication path between two switching elements of the hierarchy allowing communications between peripherals to bypass the host.
