All protected by Patent Law in scope of the presently claimed invention.
A kind of embodiment 1, load-balancing method based on wireless routing device response speed, this method is applied in wireless network
In network region, there are wireless routing device (AP) group, wireless terminal device (STA), then to connect when there is new wireless terminal device
It is fashionable, by the load-balancing method of the present embodiment, the effect that has been in admirable proportion can be reached, as shown in the flowchart of fig.1, can be with
Carry out as follows：
Step S1, wireless terminal device sends probe requests thereby (Probe Request) in wireless zone to all channels
Frame；
Step S2, the wireless terminal device carries out being selectively accessing wirelessly according to the response speed of wireless routing device
Routing device, with balance network load.
This programme is realized based on some characteristics of wireless routing device (AP), wireless routing device (AP)
In the case that load is big, CPU will forward substantial amounts of data, and especially in the case of monokaryon, its response can become slow, namely
With increasing for load, response speed is gradually slack-off, then the proposition of this scheme is just to rely on wireless routing device (AP)
This response speed can be the characteristics of load number changing and changing, both are the relations in inverse ratio, then by current
The situation of the response speed of wireless routing device (AP) simultaneously informs wireless terminal device (STA), can allow wireless terminal device
(STA) preferably make a choice to access, can just be more effectively carried out the task of equally loaded, the scheme that the application is related to is main
It is directed to the wireless routing device (AP) of monokaryon cpu system, and for the wireless routing device (AP) of multi-core CPU system, then needs
Certain Software for Design is wanted to ensure that wireless routing device (AP) response time and its actual loading have certain relation, for example into
Direct ratio etc., realizes that this programme can be loaded somewhat a bit with respect to monokaryon cpu system, and the application is no longer extended, and the description below is also
It is to be launched with the wireless routing device of monokaryon CPU (AP).
According to wireless routing device (AP) feature being previously mentioned, further design：In step s 2, the wireless terminal
The wireless routing device that equipment choice is responded at first is as the target device for accessing, the wireless routing device that responds at first
The wireless terminal device is for the most fast wireless routing device of the response speed in the wireless network for requiring to enter.It is general wireless
Region has different wireless networks, and is made a distinction by SSID (Service Set Identifier), generally,
SSID is the name taken to wireless network, when wireless terminal device needs access wireless routing device to carry out equally loaded task
Before, be the wireless network that to determine required entrance, in the wireless network that the requirement enters respond at first without circuit
The target device that wireless terminal device will will be accessed is only by equipment.In the further design, in addition it is also necessary to further emphasize,
The wireless routing device is showed the response speed of probe request by the response time, the response of the wireless routing device
Time is directly proportional to the actual loading of the wireless routing device, and this feature is possible to can the presence of unstability, load balancing
Precision can somewhat problem, so the load balancing operation higher for stricti jurise, precision, it is desirable in wireless routing device
(AP) when designing, the be directly proportional stability of this feature of wireless routing device (AP) response time and its actual loading will ensure.
In addition in whole response process, the wireless routing device sends probe response (Probe by wireless terminal device
Response) frame is responded.
And the method for the judgement of the wireless routing device for responding at first has various, the present embodiment provides a kind of, that is, receive the
One principle, is construed to first probe response in wireless terminal device (STA) receives the wireless network for requiring to enter
Wireless routing device (AP) corresponding to (Probe Response) frame, then the equipment be set to target device, for example：
Wireless terminal device (STA) can obtain the SSID information of a large amount of wireless networks before equally loaded is carried out, its
It is used as objective network by selecting the network of one of SSID1；
Then, when wireless terminal device (STA) determine receive first mark SSID1 Probe Response frames with
And it is AP1 to send the AP of this Probe Response frame, then can be done when wireless terminal device (STA) carries out load balancing
Go out selection and association request is sent to AP1.
The flow chart of above-mentioned preferred scheme is as described in Figure 2.
To sum up, it is of the invention effectively to carry out the situation of reaction load by the real-time response speed of wireless routing device
To wireless terminal device, wireless terminal device also carries out the selection wireless routing to be accessed and sets by response speed this index
It is standby so that the operability of wireless terminal device is stronger, essentially without lean on AP, AC apparatus assembly network itself,
And flexibility can be effectively improved, the operation of method is also relatively simple, meanwhile, serious forgiveness is high, and load balancing accuracy is high, effect
Also can be better, the utilization rate of Internet resources can be higher, and the probability for network problem occur can be smaller.
Embodiment 2, based on the method for embodiment 1, wherein the method for the judgement of the wireless routing device for responding at first, passes through
First treatment of principle, generally problem is not very big, and can be realized well, but due to wireless terminal device
(STA) there is sequential to probe requests thereby (Probe Request) frame transmission on each channel, namely will not simultaneously to
Each channel sends probe requests thereby (Probe Request) frame, if response speed is all very fast and much the same situation etc. under,
Then occur, first Probe Response frame for receiving is not necessarily the most short response time, a kind of more essence is described below
True determination methods, i.e., the most fast wireless routing device of described response speed is obtained as follows：
Step 1), the wireless terminal device is calculated and stores the response time of each wireless routing device, and by each
Response time is marked with corresponding wireless routing device；
Step 2), the wireless terminal device is from step 1) in each wireless routing device response time in filter out sound
It is value minimum and the wireless routing device corresponding to the value minimum response time is most fast as response speed between seasonable
Wireless routing device.
The process as depicted in the flow chart of fig.3, for example：By corresponding probe requests thereby (Probe Request) frame and
The statistics for sending and receiving the time of probe response (Probe Response) frame, by the method for existing many Time Calculations
Can obtain, it is necessary to set timer etc. for the unit of Time Calculation, that is, this real-time response time just can be more preferably
Ground, more realistically express loading condition, the most fast wireless routing device of the response speed for so obtaining relatively very it is accurate very
It is many, generally, the nothing corresponding to receive first probe response (Probe Response) frame mentioned in embodiment 1
The response time of line routing device is also most short one in the wireless network that requirement enters.
And the scheme that the selection of the wireless network for requiring to enter is used, it is also by a relatively simple, by following step
Suddenly obtain：
Step S2.1, the wireless terminal device collects radio network information, namely SSID letters by beacon (Beacon)
Breath；
Step S2.2, target is selected in the radio network information that the wireless terminal device is collected into step S2.1
Network is used as the wireless network for requiring to enter.
For example：Be to be capable of achieving in 802.11 standards, wireless terminal device by beacon (Beacon) be collected into SSID1,
The multiple radio network information such as SSID2, SSID3, then, autonomous selection will such as enter SSID1 networks, just where selection SSID1
Wireless network, and be to select the wireless routing device in the wireless network to clamp-on in load balancing, flow as described in Figure 4
Figure, this process can be completed before wireless terminal device sends Probe Request frames, because wireless terminal device exists
Into after wireless zone, a large amount of SSID information of the beacon collection are can be by, but, send Probe Request frames
Cannot become to all of channel, because early stage collects SSID information, related AP will not be a lot, may not confirm
The presence of all AP, it is all or to be sent in all channels and ask, and respond, loadbalancing tasks can be just better achieved；
Certainly, said process can be to be completed before association request is sent in wireless terminal device, because wireless terminal device is also
Be need by determination the network to be entered could select out for wireless routing device be used as target device, based on this,
The calculating of response time is optionally, if the confirmation of SSID is in early stage, in can only calculating corresponding SSID
The response time of AP, can just judge which is the wireless routing device of fastest response, if the confirmation of SSID is in the later stage,
Then or the response time of all AP is calculated, the difference that may then pass through SSID is sorted out, so, SSID confirms
Afterwards, it is possible to select response time in the network of corresponding SSID minimum AP as target AP.
In the present embodiment, it is discussed further, the problem that wireless signal sends is in step sl, described in order to reduce interference
Wireless terminal device sends probe request successively to the wireless routing device being arranged on the different channels.It is provided below one
Specific one embodiment：Wireless terminal device can send Probe Request frames on all channels, and in 2.4G frequency ranges
Only 3 independent channels, in order to reduce interference, adjacent AP is arranged on different independent channels, such as in Fig. 5,
It is to believe one by one when wireless terminal device sends Probe Request frames on the different channels that AP1, AP2, AP3 are
Sent on road, sent simultaneously rather than all signals.
Relative to embodiment 1, the present embodiment further optimizes, and can guarantee that the validity of load balancing, accuracy enter one
Step is improved, and the control for network blockage can be more excellent.
Embodiment 3, a kind of SiteServer LBS based on wireless routing device response speed, including：
Transmitting element, probe request is sent for wireless terminal device in wireless zone to all channels；
Response unit, responds for wireless routing device to the probe request that the transmitting element sends；
Judging unit, for the wireless routing device for judging to be responded at first in response unit；
Load Balance Unit, for the wireless routing for responding at first that wireless terminal device is judged to the judging unit
Equipment sends association request.
System diagram as shown in fig. 6, the system be applied to embodiment 1,2 provide load-balancing method, by transmitting element,
The execution of response unit, in the judging unit stage, the judgement of the wireless routing device for responding at first is that have certain limitation, because
It is the multiple AP for there are multiple wireless networks, so to have been distinguished to these AP, distinguishes different using SSID at present
Wireless network, and the wireless routing device that this unit is responded at first should the required nothing for entering of wireless terminal device
In gauze network, namely the AP of heterogeneous networks is distinguished by SSID, so the wireless routing device for responding at first is not all
In AP at first, but mark requires the AP that wherein responds at first in the AP of the SSID of the wireless network of entrance.
And the judgment mode of judging unit can use relatively simple judgment mode：Confirm that wireless terminal device is received
The reply of the AP in the wireless network entered required by first, can with by Probe Response frame modes, with example,
Wireless terminal device requirement enter network for SSID1 network, then, and wireless terminal device send Probe Request frames to
All of channel, after the AP in these channels receives Probe Request frames, replys Probe Response frames to wireless whole
End equipment, merges the Probe Response frames for receiving first mark SSID1, and send this Probe on wireless terminal
The corresponding AP of Response frames is AP1, then wireless terminal device begins to carry out load balancing action：AP1 is sent and is associated
Request, the AP1 target devices as to be accessed.And the determination of the wireless network of required entrance can be in early stage, it is also possible to
It is in the later stage, if if it just be can confirm that before receiving all response frames, judging unit can be only for required entrance
Wireless network in the order that receives of response frame of AP carry out arrangement and judge, determine SSID's if in the later stage
Words, then be accomplished by carrying out all of AP the order that response frame receives and be ranked up, and according to the difference of SSID, is grouped,
According to the action determined after SSID, first Probe Response frame for receiving in corresponding SSID map networks is selected
Corresponding AP as target access device.
Above-mentioned scheme, due to wireless terminal device send request be not simultaneously, so there is sequential, institute
It is not necessarily most accurate with the judgement of first, if using following schemes, can more optimize,
The judging unit includes：
Response time computing unit, for calculating response time of the wireless routing device for probe request；
Response time memory cell, for store response time that the response time computing unit is calculated and with sound
Corresponding wireless routing device information between seasonable；
Comparing unit, the size for comparing the response time that different radio routing device is responded；
Acquiring unit, for obtaining the wireless routing device for responding at first according to the comparative result of the comparing unit.
Here, to the further refinement of judging unit, by the calculating to the response time, can more be accurately determined wireless
The response speed of routing device, so making a decision can more precisely, and relatively reliable for load balancing, the response time can use
The existing transmission such as mark time, the computational methods acquisition for receiving the time, each network different due to further relating to SSID here
Problem, so the operation including computing unit, acquiring unit is also flexible, such as：When choosing of the wireless terminal device to SSID
Selecting is completed in early stage, then response time computing unit can be only for the AP in the wireless network for SSID for requiring to enter
Response time, the signified response time is in the present invention, and wireless terminal device sends corresponding Probe Request frames
Start, Probe Response frames and final wireless terminal device are sent after receiving Probe Request to wireless routing device
This period of the Probe Response frames is received, is discussed back, because the response time for calculating is objective network
In AP, then comparing unit only these AP can be carried out with the comparing of response time, the response time, minimum being was wanted
The target AP of access；And if the selection when wireless terminal device to SSID was completed in the later stage, such as responded at first in acquisition
Wireless routing device before if, then need to calculate the corresponding response time of all AP, and not only in comparing unit
The comparing of the response time of all AP is carried out, also the AP in the wireless network of different SSID is made a distinction, can be divided
The comparing of group, the AP in the wireless network of different SSID is carried out the comparing and sequence of response time size respectively, obtains single
If first acquired primarily directed to the selection to be entered after corresponding SSID wireless network in AP come, therefrom choose
Response time minimum is selected, and if just completion SSID confirms after being stored if in the response time, then in comparing unit
Can be compared according only to the AP in the wireless network of the SSID of required entrance, the AP for therefrom choosing Best-case Response Time is
Can.So, in the problem of wireless network selection, it is desirable to have special unit solves this problem, can be using such as lower section
Case：
The acquiring unit includes：
Wireless network select unit, for the wireless network that wireless terminal device selection requires to enter；
Subelement is obtained, is passed through for the minimum wireless routing device of the response time in the wireless network that will require entrance
The comparative result of comparing unit draws.
Wherein, wireless network select unit is exactly for selecting and determines that the wireless network of the corresponding SSID that requirement enters is made
It is the objective network for entering, the wireless routing device (AP) that acquisition subelement is also directed in the wireless network of required entrance comes
