Abstract

The invention provides a message forwarding method and device. The method is applied to AP equipment, and comprises the following steps of: when first STA equipment roams to the AP equipment, obtaining the first MAC address of the first STA equipment, sending a request message carrying the first MAC address to the AC equipment, receiving a response message carrying a first VLAN identifier returned by the AC equipment, and keeping the corresponding relationship of the first MAC address and the first VLAN identifier; and, when a data message from the first STA equipment is received, judging whether the MAC address corresponding to the first VLAN identifier includes the MAC address carried in the data message or not, and if so, sending the data message. By means of the message forwarding method and device disclosed by the invention, pressure on the AC equipment cannot be caused; and the communication capability of a wireless network is ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for forwarding messages. Background technique [0002] The current WLAN (Wireless Local Area Network, wireless local area network) provides an extended service set (Extended Service Set) service. In ESS, multiple AP (Access Point, access point) devices use the same SSID (Service Set Identifier, service Set ID), STA (Station, wireless terminal) devices can be associated with AP devices, and use wireless network services through WLAN. [0003] WLAN roaming refers to the process in which STA devices move between AP devices that belong to the same SSID without interrupting user services. If the VLAN (Virtual Local Area Network, virtual local area network) associated with the STA device changes before and after roaming, it belongs to wireless layer-3 roaming. [0004] In the prior art, after the STA device roams, it usually uses the centralized forwarding ...
