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 14):
The apparatus according to  claim 12 , wherein after sending the first ARP request to the destination switch, the processor is caused to perform the method further comprising:\n if a second ARP response is received from the destination switch, sending the second ARP response to the first switch; or if in specified duration, an ARP response is not received the destination switch, deleting the ARP entry corresponding to the first ARP request and that is stored locally, 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.
