The invention provides a method and system for communication between processors. Rather than provide an external network connection solely for providing a communication link between CPUs, the present invention utilizes the network devices to transfer information between CPUs. A transmitting network device marks a control packet, which is intended as a communication between CPUs, as control traffic. The receiving network device will determine whether the received control packet is intended for its own CPU and provide the control packet to its CPU if that is the case.
