Embodiment Construction

[0035] by figure 1 Take the network as an example, the wireless terminal STA and the remote access bridges AB-Client1 and AB-Client2 access the central access bridge AB-Center, and the computer terminals PC1, PC2 and PC3 are respectively connected to the AB-Center and AB-Client1 and AB-Client2. This is a simplified example. In practical applications, AB-Client1, AB-Client2, and AB-Center can each connect multiple wired users, and AB-Center can also connect to more wireless terminals and remote access bridges.

[0036] The realization method of wireless local area network bridge transparent bridging of the present invention comprises the realization method of central access network bridge transparent bridging and the realization method of corresponding remote access network bridge transparent bridging.

[0037] The wireless terminal list, the remote access bridge list and the MAC address table need to be created on the central access bridge AB-Center, and the connected wireles...

Abstract

This invention discloses a method for realizing WLAN mail bridge transparent connection including a process flow of center and remote acc mail bridge to data frame, if the frame has labels of remote acc mail bridge, the central mail bridge recovers its source MAC address and length and if the target port is monadic data frame, it should be replaced by MAC address and labeled while other data frames are forwarded directly by the transparent mail bridge, after data frames received, the target MAC address and length are recovered for those having labels of the central acc mail bridge, and those sent to the port should be replaced by source MAC address and labeled to be forwarded by the transparent bridge.

Description

technical field [0001] The invention relates to a communication method of a wireless local area network, in particular to a method for realizing wireless communication by using a central access network bridge and a remote access network bridge for transparent bridging in IEEE 802.11 wireless local area network networking. Background technique [0002] With the popularization of wireless LAN applications, in some areas where it is difficult to set up a network through cables, transparent bridging through wireless LAN bridges solves the problems that traditional wired networks cannot overcome, and this application is more and more popular among users. welcome. The so-called transparent bridging means that the content of the received data frame is not changed, and the data frame is transparently sent to the destination according to the data frame forwarding rules. [0003] In actual networking, a central access bridge (AB-Center) is usually deployed in the central area, and th...
