ABSTRACT:
An expandable local area hub network is provided by the present invention. The network comprises a plurality of hubs interconnected for direct communication. Each hub includes a plurality of ports for interfacing with remote stations, wherein the remote stations make requests that packets be transmitted on a memory coupled to the plurality of hubs. In use, one of the plurality of hubs is designated as a temporary controlling hub having controlling access to the memory bus to transmit packets on the memory bus. The temporary controlling hub relinquishing access to the memory bus when the temporary controlling hub has no requests to dispatch a packet on said memory bus.
