According to an example, in an AC pool including a MAC and a plurality of LACs registered on the MAC, after a first LAC is registered on the MAC, the MAC issues a first traffic rule to the first LAC, wherein the first traffic rule redirects a discovery packet sent from an AP to the MAC. When receiving the discovery packet sent from the AP or receiving a discovery packet sent from the AP and forwarded via a LAC, the MAC selects, from a plurality of the LACs, a second LAC for handling the AP. The MAC generates a second traffic rule associated with the AP and the second LAC, and issue the second traffic rule to a plurality of the LACs, so that when another LAC receives a communication tunnel protocol packet sent from the AP, the other LAC redirects the communication tunnel protocol packet to the second LAC.
