Abstract: An access point (AP) in an AP cluster is provided. During operation, the AP can identify a set of Internet Protocol (IP) addresses of permitted devices in a virtual local area network (VLAN) of the AP cluster from a first set of packets. The AP can also identify a set of media access control (MAC) addresses corresponding to the set of IP addresses from a second set of packets. The AP can then generate a whitelist comprising the sets of IP and MAC addresses. The whitelist can indicate addresses of packets permitted to be forwarded via the wireless interface. The AP can identify a target IP address in an Address Resolution Protocol (ARP) request. If the target IP address is absent in the whitelist, the AP can preclude the wireless interface from forwarding the ARP request to clients wirelessly coupled to the wireless interface.

Abstract: One aspect can provide a system and method for fast Wi-Fi roaming. The system can identify forwarding data associated with a first active session of a first application running on a client device coupled to a home access point (AP), determine a number of neighboring APs comprising a target AP, maintain a roaming cache on each of the neighboring APs, and synchronize the identified forwarding data associated with the first active session to the roaming cache on each neighboring AP. In response to determining that the client device is roaming to the target AP, the system can access the roaming cache on the target AP to obtain the forwarding data associated with the first active session in order to continue the first active session on the client device with reduced roaming latency, thereby facilitating fast roaming of the client device from the home AP to the target AP.
