Abstract: The compact brouting switch allows communication between external systems with differing or same protocols. The compact brouting switch includes switch ports which receive and transfer data between the external systems. A processor in the switch controls the movement of data within the switch and assigns data to specific switch ports to transfer data to specific external systems. However, the switch ports also have the capability of directly transferring data from one external system to another external system bypassing the processor.
