Problems solved by technology

The threshold here usually refers to the number of loads (and a small amount of traffic thresholds are used for configuration). When there are many uplinks and downlinks), the new STA can still access the AP, which will cause network congestion; similarly, this problem will also occur if the traffic is used as a judgment condition without considering the load quantity

Embodiment 1

[0021] The invention adds a network traffic monitoring function on the basis of the existing load balancing strategy, so that the load balancing effect is better and the network is more stable.

[0022] Specifically, please refer to figure 1 As shown, a wireless network architecture with a load balancing function, which consists of a router 20, an access controller 30, a switch 40, and at least two wireless access points (here, the first wireless access point 51 and the second wireless access point Access point 52 as an example), each wireless access point is connected to the Ethernet 10 through the switch 40, the access controller 30 and the router 20 in sequence, and the access controller 30 (for example, using Foundry AF-AC1000) as the load A balanced executive device, used to monitor the number of wireless terminals 70 (STA) accessing each wireless access point, and the wireless access point periodically sends the information of the wireless terminal 70 associated with it ...

Embodiment 2

[0026] Embodiment 2 is an improvement on the basis of Embodiment 1. It connects the network probe between the corresponding wireless access point and the switch, and implements flow measurement through link monitoring. Specifically, please refer to figure 2 As shown, a first optical splitter is installed on the link between the first wireless access point 51 and the switch 40, and a second optical splitter is installed on the link between the second wireless access point 52 and the switch 40. A network probe 61 and a second network probe 62 are respectively connected to the first optical splitter and the second optical splitter. Because the link transmits optical signals, the optical splitter replicates the optical signals on the link (one beam of light becomes two beams of light) to complete the purpose of traffic monitoring.

Embodiment 3

[0028] In the third embodiment, on the basis of the first embodiment, the redundancy of the access controllers is increased, and when one of the access controllers fails, another access controller is activated. For details, please refer to image 3 As shown, the first access controller 31 and the second access controller 32 are the active and standby access controllers respectively, and both the first access controller 31 and the second access controller 32 are connected to the switch 40 and the router Between 20, the output signals of the first network probe 61 and the second network probe 62 are sent to the first access controller 31 and the second access controller 32, while the first access controller 31 and the second The access controllers 32 are connected by a heartbeat line to monitor the status of each other in real time. When the first access controller 31 fails, the second access controller 32 is started. Of course, the structure of the second embodiment can also b...

Abstract

The invention discloses wireless network architecture with a load balancing function and relates to the technical field of a wireless network. The architecture comprises a router, an access controller, a switch and at least two wireless access points. Each wireless access point is connected with an Ethernet through the switch, the access controller and the router in sequence. A network probe is connected with each wireless access point. The output end of the network probe is connected with the input end of the access controller. According to the architecture, traffic and the number of loads are taken as conditions for STAs (Stations) to access APs (Access Points). When the APs satisfy the condition that both the traffic and the number of the loads are smaller than corresponding threshold values, new STAs are allowed to access, network congestion is prevented, and the stability of the wireless network is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a wireless network architecture with a load balancing function. Background technique [0002] With the increasing demand for intelligence and wireless network coverage of wireless terminals (mobile devices such as mobile phones and wireless devices such as tablets and laptops), the application of wireless APs (Access Points) is also becoming more and more extensive. The access point for users with wireless terminals to enter the wired network is mainly used in broadband homes, shopping malls, campuses, parks, warehouses, factories and other places. The typical distance covers tens of meters to hundreds of meters. [0003] In a traditional wireless network, STA (Station station, that is, wireless terminal) communicates with each wireless AP to obtain information such as signal strength through active scanning or passive scanning mode, and finally selects the AP with the ...
