Problems solved by technology

[0009] Since only one WDS link is in working state between two APs, in a WLAN (Wireless Local Area Network, wireless local area network), this link is easily interfered by interference signals, so that the wireless link between the two APs The link may become a performance bottleneck for the wired network on both sides

Embodiment Construction

[0055] The core idea of ​​the present invention is: two APs are in running state, respectively connected to the wired network, and a WDS link is established between the two APs to connect the wired networks on both sides. Two WDS links (dual frequency) can be established between two APs, one for 11a (11an) and one for 11g (11gn), such as figure 2 shown. After the two links are successfully established, in order to prevent loops, STP (SpanningTree Protocol, Spanning Tree Protocol) blocks a port of a certain AP; then, the two links are added to the meshlink-group according to certain rules, At this time, the meshlink interface information corresponding to the original meshlink interface is shielded and invisible to the entire system, and the interface information visible to the entire system is the meshlink-group interface information. The heartbeat packets of the two links remain unchanged. If data forwarding is performed, meshlink-group will select one to forward according ...

Abstract

The invention discloses a method and a device for bonding wireless distribution system links, which are used in a network having at least two access points AP. The method comprises the following steps that: wireless mesh link-groups are established on the two APs in the network respectively; the APs detect the establishment state of the WDS links, add the successfully established WDS links matched with the parameters in the mesh link-groups into the mesh link-groups, and shield mesh link interface information corresponding to an mesh link interface of the WDS links added into the wireless mesh link-groups; and the APs forward data by using the mesh link groups. The method and the device realize the redundancy backup of the WDS links, improve the reliability of the system and the performance of the WDS links and realize spectrum spreading.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a WDS link binding method and device. Background technique [0002] In the application scenario of WDS (Wireless Distribution System, wireless distributed system), it is often necessary to establish a WDS link between two APs (Access Points, access points) to connect the wired networks on both sides of the AP to realize bridge. E.g figure 1 As shown, a WDS link is established between AP1 and AP2, so that LAN segment 1 and LAN segment 2 of a wired network are connected. In this case, the traffic that needs to pass through the WDS link may be heavy. [0003] The WDS connection includes two processes of WDS connection establishment and WDS connection teardown, which are implemented through the interaction of three WDS connection management Action frames: Peer LinkOpen (open) / Confirm (confirm) / Close (close), including the following steps: [0004] 1. Perform WDS ne...
