Abstract
A system for handling address resolution protocol (ARP) messages has a plurality of communication modules for communicating via a network. Each such communication module has a separate link layer address (e.g., MAC address). Control logic in communication with each of the modules serves as an ARP proxy for the modules. Rather than using its own link layer address in the overhead of the ARP messages, the control logic uses the link layer addresses of the communication modules, thereby causing the network to learn these link layer addresses during ARP processing. Therefore, once ARP messaging between a communication module and a remote network device has been performed, the network has established a data path between the communication module and the remote network device, thereby helping to prevent or reduce message flooding when the two devices begin to communicate.
