Description
Technical field
The present invention relates to wlan network technical field, particularly relate to a kind of WLAN networking and management method thereof.
Background technology
Recent years, wireless network was flourish, the networking scale of wireless network also grows stronger day by day, from initial several or tens AP(wirelessAccessPoint, WAP (wireless access point)) form a wireless network, develop into and nowadays comprise thousands of even several thousand AP in a wireless network.Network size expands, and means that the difficulty of network management and O&M increases.The management means of wireless network, also from initial single-point independent operating, develops into by an AC(wirelessAccessController, wireless controller) equipment is as central administration node, until the most emerging high in the clouds management platform based on cloud.
Existing wireless network generally adopts following two kinds of methods: 1. the networking mode of traditional AC+FitAP formula, and AP all in network passes through proprietary CAPWAP tunnel and is connected with an AC equipment.AC is the Centroid of whole wireless network, can be configured AP by AC, manage and monitor, all wireless datas are also all sent on AC by tunnel, forward process is realized by AC, because all wireless datas all pass through AC, therefore can concentrate on AC easily and realize the wireless traffic such as RRM, Roaming control.But this mode exists following shortcoming: because AC is as the Centroid of whole wireless network, configuration managements all in network, the function of data retransmission are all born by it, and therefore AC is easy to the bottleneck node becoming whole network.Especially, after 802.11n/802.11ac technology occurs, injection Theoretical Rate frequently has reached hundreds of Mbps to 1Gbps, if all wireless flows all pass through AC, AC can become the bottleneck of message repeating undoubtedly.
2., along with the development of cloud, occurred utilizing publicly-owned cloud to carry out the product form of Wireless Communication Equipment registration and management.AP equipment all independent operatings all in network, are similar to the form of initial FatAP.All wireless traffic process all complete on AP, and especially all wireless datas are all directly forward on AP, avoid the bottleneck problem that the single AC node in scheme one causes.The effect of publicly-owned cloud platform is registered and configuration management each AP exactly, also provides the real-time monitoring to AP running status in addition.The shortcoming existed: based in the wireless networking mode of cloud platform, the effect of cloud management platform is exactly that the identity of AP does certification, additionally by cloud platform AP be managed for configuration and issue, in network, operation between each AP node is independently, and the business therefore participated in as the multiple AP of this needs such as RRM RRM (RadioResourceManagement) and roaming is difficult to realize.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned problem, the group-network construction of layering is adopted by the present invention, the function of AC is dispersed in multiple functional layers of network, both the centralized management of configuration had been achieved, achieve again the distributed forwarding of wireless data, also support RRM and the Roaming control of local.

Illustrate below by the detailed construction of embodiment to this WLAN networking and management method thereof:
embodiment 1:
As shown in Figure 1, first using the management platform of Cloud Server as the first floor i.e. cloud management level, then AC layer is set at lower one deck of cloud management level, AC layer and cloud management level pass through wireless connections, wherein AC layer is provided with plural wireless exchange board, arrange the AP layer of multiple AP antenna below wireless exchange board, user side can carry out being associated being connected on network with AP antenna.
When user side is in radio management territory, the client of access can carry out roaming switch between all AP in this territory.As radio management territory 1 comprises AP1 and AP2 by two AP antenna equipments of wireless exchange board 1 and lower extension thereof, the control procedure that client accesses and roams in radio management territory 1 is as follows:
One, when user side enters radio management territory 1 scope first, and successful association is on the AP1 of AC layer equipment;
AP1, by the relevant information of user side, comprises (including but not limited to these information) such as MAC Address, IP address, wireless key, authentication information and terminal types and directly reports wireless exchange board 1 and namely achieve user side and be linked on wlan network;
Two, when user side moves in radio management territory 1, user side roams into the scope of AP2 from AP1 simultaneously, and is associated with AP2;
After AP2 receives the association request of user side, search the relevant information that AP2 local user information table finds not this user side, then AP2 asks this user side to access to the wireless exchange board 1 in radio management territory 1, after WS1 receives the request of AP2, this user side is handed down to AP2 in the local information of AP1, AP2 preserves the information of this user simultaneously, and allows this user side to access.
Three, when user side moves to radio management territory 2 in radio management territory 1, user side roams into the AP3 in radio management territory 2 from the AP1 radio management territory 1, and is associated with AP2;
After AP3 receives the association request of user side, search the relevant information that AP3 local user information table finds not this user side, then AP3 asks this user side to access to the wireless exchange board 2 in radio management territory 2, after wireless exchange board 2 receives the request of AP3, the local information of searching in radio management territory 2 can not find the relevant information of this user side, then radio management territory 2 sends the access request of user side to cloud management platform, then the relevant information of this user is handed down to wireless exchange board 2 by cloud management platform, be handed down to AP3 again, AP3 preserves the information of this user simultaneously, and allow this user side to access.
Achieve user side will roam at this internetwork each independent AP antenna.
Wireless exchange board and its lower antenna AP hung form a radio management territory, and be between the AP antenna in same radio management territory and can realize RRM control, wireless client also can be roamed between these AP antennas.
The AP antenna hung under wireless exchange board can be determined by following strategy:
If AP antenna is directly connected with wireless exchange board, then this AP antenna is exactly the lower extension AP of direct-connected wireless exchange board;
If when AP antenna does not have direct-connected wireless exchange board again, on AP antenna, Lian electricity Hou is directly connected to cloud management platform, cloud management platform is according to circumstances that it specifies a wireless exchange board again.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
