A pppoe implementation method at the wlan subnet end

Abstract

The invention discloses a PPPoE (point-to-point protocol over Ethernet) realization method for a WLAN (wireless local area networks) sub net terminal. After an upstream PPPoE message sent by a client terminal is received by wireless client end access equipment, a mark which can be used for uniquely identifying the client terminal and can not be changed in primary interaction is extracted from the upstream PPPoE message, the mark and a source MAC (media access control) address in the PPPoE message are stored into a terminal address corresponding table, and the source MAC address in the PPPoE message is replaced into the wireless MAC address of the wireless client end access equipment by the wireless client end access equipment; and after a PPPoE downstream message from a wideband access server sent by a wireless access point is received by the wireless client end access equipment, the mark is extracted from the downstream PPPoE message, according to the mark, the MAC address corresponding to the client terminal is found from the terminal address corresponding table, and then a target address in the PPPoE message is replaced into the MAC address of the client terminal. The technical scheme has the beneficial effects that the PPPoE realization method is simple and feasible, the functional requirement on the wireless access point by WLAN is reduced, and PPPoE connection that a sub net is connected with a local area network in a wireless manner is realized.

Description

technical field [0001] The invention relates to a control method of a wireless local area network, in particular to a method for realizing PPPoE (Point-to-Point Protocol over Ethernet) at the subnet end of a WLAN (Wireless Local Area Networks wireless local area network). Background technique [0002] In the existing wireless local area network, if the terminal is directly connected to the local area network wirelessly, that is, the client terminal-wireless access point-broadband access server mode networking, the terminal can successfully communicate with the BAS (Broadband Access Server) through PPPoE dial-up. server) to interact. However, if the subnet is connected to the LAN through wireless means, such as the networking mode of client terminal-wireless client access device-wireless access point-broadband access server, due to the interaction process between the wireless access point and the wireless client access device In this case, the packets must use the peer MAC o...

However, if the subnet is connected to the LAN through wireless means, such as the networking mode of client terminal-wireless client access device-wireless access point-broadband access server, due to the interaction process between the wireless access point and the wireless client access device In this case, the message must use the peer MAC of the two devices as the destination MAC, so that the upstream message of the client terminal cannot reach the BAS, and the downstream message of the BAS cannot reach the client terminal, so PPPoE cannot be implemented.
