Abstract
A method and device for processing an address resolution protocol (ARP) in a software-defined networking (SDN) environment is disclosed. The method includes receiving, by a first network device, an ARP request packet from a first terminal so that the first terminal communicates with a second terminal and transmitting, by the first network device, an ARP response message including MAC address information of the second terminal to the first terminal as a response to the ARP request packet. Accordingly, a load of the controller can be reduced by sharing and processing an ARP proxy function with the network device in the SDN environment.
