Method and device for implementing load balancing

A device for implementing load balancing, comprising a control module, a load calculation module, a parsing module and a transmission/reception module, wherein

• the control module is configured to control the load calculation module and the parsing module to determine whether itself is overloaded when a first AP is to transmit data received from an STA which has accessed the first AP, and to determine other APs for load sharing when determining that itself is overloaded;
• and
• the transmission/reception module is configured to offload the received data to said other Aps;
• wherein when determining other APs for load sharing, the control module is configured to:
• in way 1, receive Beacon frames of said other APs, control the parsing module to extract loads of said other APs in Beacon frames;
• or
• in way 2, broadcast a load balancing request to said other APs, receive load balancing responses by said other APs;
• wherein the control module is further configured to:
• in way 1, add a load of a wireless AP into a standard Beacon frame so as to be broadcasted by adding the load of the wireless AP into a Frame Body field of the standard Beacon frame;
• in way 2, reconstruct a Sub Type field of the standard Beacon frame to form a special frame for broadcasting a load balancing request of the wireless AP, and control the parsing module to parse a reconstructed Beacon frame after the reconstructed Beacon frame is received and return a load balancing response according to a structure of the reconstructed Beacon frame;
• wherein the load of the wireless AP is added into a Frame Body field of the load balancing response.
