Abstract

The invention discloses a data transmission method and data transmission equipment. The method comprises the following steps that: access controller (AC) equipment judges whether a keep-alive message from access point (AP) equipment is received or not; if the keep-alive message from the access point (AP) equipment is received, the AC equipment determines that a controlling and provisioning of wireless access point (CAPWAP) tunnel is normal and acquires a Session ID corresponding to the AP equipment from the keep-alive message; and the AC equipment maintains the information of the CAPWAP tunnel for the AP equipment according to the session ID. The method and the equipment can adapt to different network address translation (NAT) environments and lighten network maintenance burden.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique

[0002] WLAN (Wireless Local Area Networks, wireless local area network) provides a wireless connection service of a local area network, which can provide high-speed wireless data access, and has been widely used in various places such as cities, enterprises, buildings, and families. Compared with the traditional wired access method, the wireless local area network allows network users to be more free, completely getting rid of the shackles of cables and port locations, and the wireless local area network makes the terminal easy to carry, easy to move, etc., eliminating or reducing Complicated network wiring, only need to place one or more AP (Access Point, Access Point) devices to establish a local area network covering the entire building or region.

[0003] In the current wireless local area networ...
