Description
Technical field
The present invention relates to WLAN（WLAN, Wireless Local Areal Network）Technical field, especially
It is to be related to one kind in WDS（Wireless Distribution System, hotspot compartment system）Or wireless bridging situation
Under loop detecting method, loop detection means and loop detection system.
Background technology
Wireless network generally overlays a certain region of user's request, and is by multiple AP
（WirelessAccessPoint, wireless access points）The Mesh network of composition（Wireless mesh network）.
One important function of AP is exactly to relay, and so-called relaying is exactly that wireless signal is amplified one between two wireless points
It is secondary so that the client of distal end can receive stronger wireless signal.An AP for example is placed in a points, and has one in c points
Client, between have 120 meters of distance, weakened much to c point signals from a points, then the b points at 60 meters of midway put one
Individual AP just can effectively strengthen as relaying, the signal of the client of such c points, it is ensured that transmission speed and stability.
The important function of another of AP is bridge joint, and bridge joint is exactly to link two end points, between realizing two wireless aps
Data transfer, it is desirable to which two cable LANs are coupled together, general just selection is bridged by AP, for example, have one in a points
15 cable LANs of computer composition, the cable LAN that b points are made up of 25 computer, but the distance of 2 points of ab is very
Far, 100 meters have been exceeded, it is impossible by wired connection, then how two LANs being linked together, this is accomplished by
One AP is respectively set in a points and b points, AP bridging functionalitys are opened, the LAN that 2 points of such ab just can mutually transmit data.
It is noted that, there is no the AP of WDS functions, 2 points is no wireless signal covering after bridge joint.
In some wireless coverage areas, such as some scenic spots more remote by position, network layout is difficult deployment, this
When be accomplished by carrying out distributed deployment with WDS, i.e., using certain frequency range of AP, such as 5G is linked into another as data feedback channel
Individual AP.
In addition, also there is some scene flows of the people big, in order to improve the reliability of whole wireless system, by it is wired it is up with
Wireless uplink comes into force simultaneously, i.e. access in radio POE（Power Over Ethernet, active Ethernet）Interchanger, it is wireless to utilize
5G frequency ranges access another AP, when a certain bar up-link breaks down, another up-link it is replaceable it, there is provided more may be used
The access passage for leaning on.Although this solution solves the deployment issue of wireless coverage well, in practical engineering application
In be very easy to cause the loop of network link, so as to influence the normal operation of wireless network.
The content of the invention
Although the technical problem to be solved in the present invention is to overcome WDS in the prior art or wireless bridged network well

Enterprise or city field network system.In simplest network architecture, the ethernet port of bridge is connected to certain in LAN
On hub or switch, signal emission port is then connected by cable with antenna；Network system is realized by such mode
The extension of system.
As shown in figure 3, the loop detecting method is comprised the following steps：
Step 201, the topological diagram that the data link of radio reception device and radio reception device up direction is constituted is reduced to
One DAG digraphs.
Step 202, a radio reception device APi is selected from the DAG digraphs, construct a loop detection message, and
The mark of radio reception device APi is inserted in the Payload fields of the loop detection message to form set S={ APi }, will
The loop detection message is sent on the radio reception device APm being associated to the up-link with radio reception device APi.
Wherein, radio reception device APi represents i-th radio reception device, and 1≤i≤N, radio reception device APm is represented
M-th radio reception device, 1≤m≤N.
Step 203, radio reception device APm receive the loop detection message, and in the loop detection message
The mark of radio reception device APm is inserted in Payload fields to form set S={ APi, APm }, by the loop detection report
Text is sent to the radio reception device APn being associated with the up-link of radio reception device APm.
Wherein, radio reception device APn represents n-th radio reception device, 1≤n≤N.
Step 204, radio reception device APn receive the loop detection message, judge in the loop detection message whether
In the presence of the mark of radio reception device APn, if then entering step 205, otherwise into step 206.
Step 205, radio reception device APn stop forwarding the loop detection message, and report a discovery wireless loop
Information is to a cloud AC.
In step 205, the discovery wireless loop information includes set S={ APi, APm }.
Step 206, radio reception device APn insert this and wirelessly connect in the Payload fields of the loop detection message
Enter the mark of device A Pn, to form set S={ APi, APm, APn }, by the loop detection message send to the wireless access
On the associated another radio reception device of the up-link of device A Pn.
In this loop detecting method, identified in the presence of it in radio reception device APn judges the loop detection message
When, the loop detection message is just stopped forwarding, and will be seen that wireless loop this case reports cloud AC.Then, have from the DAG
To an optional radio reception device in other radio reception devices of figure in addition to the radio reception device crossed after testing, repeat
Perform above-mentioned loop detection flow.By this way of search, wireless network can be had soon found that with the presence or absence of loop and deposited
In how many loop.
With reference to Figure 4 and 5, name a specific example to illustrate the present invention, to enable those skilled in the art
More fully understand technical scheme：
