Claim 8:
9. The AC of claim 7, wherein, the machine executable instructions further cause the processor to:
receive a second upstream flow entry sent by a SDN controller; wherein, the second upstream flow entry is used by the AC to locally forward upstream data messages; the second upstream flow entry comprises a source IP address, a VLAN value, a source MAC address and an AP identifier;
when an upstream data message sent by a second AP is received, and a source IP address, a VLAN value and a source MAC address comprised in the upstream data message match respectively with the source IP address, the VLAN value and the source MAC address comprised in the second upstream flow entry, determine whether the second AP is an AP corresponding to the AP identifier in the second upstream flow entry; and
if the second AP is the AP corresponding to the AP identifier in the second upstream flow entry, forward the upstream data message based on the second upstream flow entry;, or,
wherein the machine executable instructions further cause the processor to:
receive a second downstream flow entry sent by the SDN controller; wherein, the second downstream flow entry is used by the AC to locally forward downstream data messages; the second downstream flow entry comprises a destination IP address, a VLAN value, a destination MAC address and an AP identifier;
when a downstream data message is received, and a destination IP address, a VLAN value and a destination MAC address comprised in the downstream data message match respectively with the destination IP address, the VLAN value and the destination MAC address comprised in the second downstream flow entry, determine whether the second AP for forwarding the downstream data message is an AP corresponding to the AP identifier in the second downstream flow entry; and
if the second AP for forwarding the downstream data message is the AP corresponding to the AP identifier in the second downstream flow entry, send the downstream data message to the second AP based on the second downstream flow entry.
