Abstract:
Embodiments of the present disclosure disclose an SDN-based ARP implementation method and apparatus. The method includes: receiving, by a controller, an ARP request sent by a first switch, and when it is determined that no ARP entry corresponding to the ARP request exists locally, sending, to the first switch, an instruction configured to instruct the first switch to flood the ARP request. In this way, the ARP request can be broadcast to an entire network by means of message forwarding between switches.

Claim (Index 7):
The method according to  claim 5 , after sending the first ARP request to the destination switch, further comprising:\n if an ARP response returned by the destination switch is not received in specified duration, deleting the locally stored ARP entry corresponding to the first ARP request and, and sending, to the first switch, a second instruction configured to instruct the first switch to flood the first ARP request, wherein the second instruction is configured to instruct the first switch to send the first ARP request to both the switch that is adjacent to the first switch and a host that is connected to the first switch.
