Abstract
A network switching hub is implemented on an IC chip, and has a bus connected to external ports through sets of direct switches, which may be sets of queue switch transistors. The direct switches are opened and closed by action of an on-board arbitrator controller following a preprogrammed arbitration scheme. In some cases the ports are parallel ports, and in others parallel ports. Data may be switched between any two ports by controlling the switching elements. Ports may be adapted to special purposes, such as PCI and hub to hub connection for expansion.
