ABSTRACT:
A switching means and method where a number of devices exchange data on a data bus. Each device has at least one data port and at least one of the devices has a plurality of data ports. The data ports may have different data rates. An arbitration takes into account availability or congestion of the ports before allowing data transport from device to device. The devices communicate directly over a cross bar.
