Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Meet
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The present invention implements to provide a kind of bandwidth speed limiting method, the equipment applied to computation bandwidth threshold value.Referring to Fig. 1, Fig. 1
For a kind of flow chart of the bandwidth speed limiting method of the embodiment of the present invention, comprise the following steps：
Step 101, the outlet bandwidth of the wireless network where the equipment of acquisition computation bandwidth threshold value, and obtain wireless network
The access total amount of client in network.
In this step, outlet bandwidth includes the upstream bandwidth and downlink bandwidth of wireless network, to calculate place
The bandwidth threshold of client in wireless network, and then bandwidth speed limiting is carried out to client according to bandwidth threshold.
Step 102, according to outlet bandwidth and access total amount, the bandwidth threshold of client in wireless network is determined, and use
Bandwidth threshold, bandwidth speed limiting is carried out to the client in wireless network.
It can be seen that in the bandwidth speed limiting method that the present invention implements offer, the equipment of computation bandwidth threshold value can be according to acquisition
The outlet bandwidth of the wireless network arrived and the access total amount of client, calculate bandwidth threshold, to use the bandwidth threshold calculated
It is worth and speed limit is carried out to the client of wireless network, avoid the occurrence of influences whole nothing because individual client occurs robbing network speed behavior
The communication quality of gauze network, ensure that all clients of access wireless network being capable of proper communication.
In one implementation, step 102 specifically includes：
By outlet bandwidth and the ratio of access total amount, it is defined as the bandwidth threshold of client in wireless network；Or
Judge outlet bandwidth and whether access the ratio of total amount less than the minimum bandwidth threshold pre-set for outlet bandwidth
Value；
If so, minimum bandwidth threshold value is then defined as to the bandwidth threshold of client in wireless network；
Otherwise, ratio is defined as to the bandwidth threshold of client in wireless network.
Wherein, the minimum bandwidth threshold value pre-set can include up minimum bandwidth threshold value and descending minimum bandwidth threshold
Value, up minimum bandwidth threshold value correspond to the upstream bandwidth of wireless network and the ratio of the access total amount of client, descending minimum
Bandwidth threshold corresponds to the downlink bandwidth of wireless network and the ratio of the access total amount of client.
In specific implementation, the minimum bandwidth threshold value pre-set can be 100kbps, it is of course also possible to according to wireless
To the minimum network speed requirement of client in network, minimum bandwidth threshold value is adjusted.
This way it is possible to avoid occur in the wireless network client be currently accessed total amount it is excessive in the case of, calculate
Wireless network outlet bandwidth and wireless network in client access total amount ratio it is too small, so as to cause client can not
The problem of carrying out normal network service, realize on the premise of ensureing that client can carry out normal network service, docking
The client for entering wireless network carries out speed limit.
In a kind of implementation of the present invention, the equipment of computation bandwidth threshold value can be to be handed in wireless network with client
Mutual access device, specifically, the access device interacted in wireless network with client can be the Fat for not possessing management function
AP.Referring to Fig. 2, Fig. 2 is another flow chart of the bandwidth speed limiting method of the embodiment of the present invention, is comprised the following steps：
Step 201, the outlet of the wireless network for the access control equipment transmission that access device is managed in wireless network is received
Bandwidth.
Wherein, outlet bandwidth is that access control equipment notifies all access devices of self-management to stop using Access Control
Behind the outlet of equipment, carry out what bandwidth detection obtained to outlet.
In specific implementation, the access control equipment for managing access device can be access controller (Wireless Access
Point Controller, AC) or possess the Fat AP of management function, it is of course also possible to be that other possess control work(
The equipment of energy.
It should be noted that access control equipment stops using Access Control in all access devices of notice self-management
Before the outlet of equipment, the business of outlet bandwidth can be taken on equipment of itself out of service first.
So, in a wireless network, only an access control equipment carries out the detection of outlet bandwidth, avoids more from setting
It is standby the outlet bandwidth of wireless network to be detected simultaneously so as to influence the accuracy of outlet bandwidth detection.Simultaneously, additionally it is possible to keep away
The business for the outlet bandwidth for exempting to run in individual device has undesirable effect to outlet bandwidth detection, further improves outlet bandwidth
The accuracy of detection.
Step 202, the access total amount of client in the wireless network that access control equipment is sent is received.
Wherein, access total amount be access control equipment according to all access devices of self-management in predetermined period to connecing
The access information for entering the client of the respective access of control device transmission is determined and sent.
In this step, by the access device of access control equipment management first according to predetermined period, to access control equipment
The access information of client each accessed is sent, then, access control equipment is according to the access information of the client received
The access total amount of client in wireless network is determined, and the access total amount of client in wireless network is sent to each access and set
It is standby, so that access device is according to the outlet bandwidth of wireless network and the access total amount computation bandwidth threshold value of client, and then use
Bandwidth threshold carries out bandwidth speed limiting to client.
In the access total amount fluctuation more frequently under scene of the client of wireless network, in a kind of implementation, access
Total amount can also be that access control equipment is being judged itself to be set to Access Control in current period according to all access devices
Client is currently accessed total amount in the wireless network that the access information of the client for the respective access that preparation is sent is determined, with from
Difference in the wireless network determined in a upper cycle between the access total amount of client is more than what is sent during predetermined threshold value.
Specifically, in order to avoid frequently adjusting the bandwidth threshold of client, access control equipment is only judging itself
The access information of the client of the respective access sent according to all access devices in current period to access control equipment is true
Client is currently accessed total amount in the wireless network made, and from client in the wireless network determined in a upper cycle
Access total amount between difference when being more than predetermined threshold value, the wireless network that determined in current period can be just sent to access device
Client is currently accessed total amount in network.That is, only wireless network clients access total amount fluctuating range compared with
In the case of big, access control equipment just can into access device more new wireless network client access total amount.
It should be understood that when in access control equipment generation a cycle in wireless network client be currently accessed it is total
During amount, because client is currently accessed total amount as sky, therefore, a cycle in the wireless network that is determined in the previous cycle
Client in the wireless network for being currently accessed total amount and being determined within the previous cycle of client in the wireless network of interior determination
The difference being currently accessed between total amount is necessarily more than predetermined threshold value.Therefore, the access total amount of the above-mentioned client in wireless network
The sending method for the access total amount that fluctuation is more frequently implemented under scene, access control equipment first time is not interfered with to access
Equipment sends the access total amount of client.
In actual applications, because the mobility of wireless network access client is larger, possible access control equipment is every
The access total amount of the client determined in the individual cycle is different from, and this bandwidth threshold that can cause to calculate frequently changes.On the other hand,
Can be by the default load number section for access total amount, to avoid the occurrence of the problem of bandwidth threshold frequently changes.
First, between presetting load amount field, load data section can have multiple, and the scope in each load number section can
To be determined according to actual conditions.
For example 10 load number sections can be set, it is specially [0,10], [11,20], [21,30], [31,40],
[41,50], [51,60], [61,70], [71,80], [81,90], [91,100], then, when the access total amount of client is in 0
When in the range of~100, it becomes possible to it is determined that corresponding load number section.So, when client access total amount fluctuating range
When smaller, for example it is 8 to increase from 1, and corresponding load number section is still [0,10].
Then, by the upper limit threshold of the load number section being currently accessed where total amount of client, it is defined as current period
Corresponding ladder accesses total amount.
For example the client that is determined in current period of access control equipment is currently accessed total amount as 1, corresponding load
Quantity section is [0,10], then, ladder access total amount corresponding to current period is the upper limit threshold 10 in load number section, only
That wants client is currently accessed total amount in the range of 0~10, and corresponding ladder access total amount is 10.So, gentle visitor
The fluctuation for being currently accessed total amount at family end, in the case of the variable quantity for being currently accessed total amount of client is less, it is believed that
The total amount that is currently accessed of client does not change.
Finally, judge that ladder corresponding to current period accesses total amount, whether is ladder access total amount corresponding with the previous cycle
It is identical, if it has not, then access control equipment sends ladder access corresponding to current period to all access devices of self-management
Total amount.
For example the client that is determined in current period of access control equipment is currently accessed total amount as 1, corresponding load
Quantity section is [0,10], and ladder access total amount corresponding to current period is the upper limit threshold 10 in load number section；The last week
The client determined in phase is currently accessed total amount as 8, and corresponding load number section is [0,10], rank corresponding to the previous cycle
Ladder access total amount is still the upper limit threshold 10 in load number section.In this case, access control equipment is without to from barrel
All access devices of reason send ladder access total amount corresponding to current period, namely access device need not recalculate bandwidth threshold
Value.
Again for example, the total amount that is currently accessed for the client that access control equipment determines in current period is 1, corresponding negative
It is [0,10] to carry quantity section, and ladder access total amount corresponding to current period is the upper limit threshold 10 in load number section；It is previous
The total amount that is currently accessed of the client determined in cycle is 20, and corresponding load number section is [11,20], and the previous cycle is corresponding
Ladder access total amount still be load number section upper limit threshold 20.In this case, access control equipment can be to certainly
All access devices of barrel reason send ladder access total amount corresponding to current period, namely access device can recalculate band
Wide threshold value.
So, when the fluctuating range of the access total amount of client is smaller, it is believed that ladder connects corresponding to current period
It is identical with ladder access total amount corresponding to the previous cycle to enter total amount, access control equipment to access device without updating client
Access total amount.It is real in order to the bandwidth threshold for the client that upgrades in time when the fluctuating range of the access total amount of client is larger
Now more preferable speed limit effect, the access that access control equipment can update client to all access devices of self-management are total
Amount.
Step 203, according to outlet bandwidth and access total amount, the bandwidth threshold of client in wireless network is determined, and use
Bandwidth threshold, bandwidth speed limiting is carried out to the client in wireless network.
The detailed process and technique effect of this step may be referred to the step 102 in the bandwidth speed limiting method shown in Fig. 1,
This is repeated no more.
It should be noted that when access control equipment is the Fat AP with management function, access control equipment is in itself
Also there is the function of access client, therefore, access control equipment is also required to the outlet bandwidth obtained according to measurement and received
Client access total amount, calculate the bandwidth threshold of client, and then the client of access is limited using bandwidth threshold
Speed.
It can be seen that in the bandwidth speed limiting method that the present invention implements offer, access device can be according to the wireless network received
The outlet bandwidth of network and the access total amount of wireless network clients, calculate the bandwidth threshold of client in wireless network；In addition, it is
Avoid frequently calculating and adjust the bandwidth threshold of client, influence client and carry out normal network service, Access Control is set
For only in the case where the fluctuating range of the access total amount of wireless network clients is larger, can just be updated to access device wireless
The access total amount of client in network.Can not only avoid the occurrence of influences whole because individual client occurs robbing network speed behavior
The communication quality of wireless network, ensure access wireless network all clients can proper communication, but also can be according to nothing
The fluctuation situation of the access total amount of line networking client, the wireless network that upgrades in time access the bandwidth threshold of client, Ke Huti
Test more preferably.
In a kind of implementation of the present invention, the equipment of computation bandwidth threshold value can be management and client in wireless network
The access control equipment of the access device of interaction is held, specifically, access control equipment can be AC or possess management work(
The Fat AP of energy.Referring to Fig. 3, Fig. 3 is another flow chart of the bandwidth speed limiting method of the embodiment of the present invention, including step as follows
Suddenly：
Step 301, all access devices of access control equipment management are notified to stop using the outlet of access control equipment.
In this step, it is out of service first before access control equipment detects to the outlet bandwidth of wireless network
The business of outlet bandwidth is taken on equipment of itself, then, notifies all access devices of self-management to stop using Access Control
The outlet of equipment, after access device receives notice, stop using the outlet of access control equipment and sent out to access control equipment
Response is sent, so that access control equipment starts to detect the outlet bandwidth of wireless network.
Step 302, bandwidth detection is carried out to outlet and obtains the outlet bandwidth of wireless network.
In this step, access control equipment goes out after the response of access device transmission is received to wireless network
Mouth carries out bandwidth detection and obtains the outlet bandwidth of wireless network, so that access control equipment computation bandwidth threshold value, and then use band
Wide threshold value carries out bandwidth speed limiting to client.
Step 303, according to all access devices of access control equipment management in predetermined period to access control equipment
The access information of the client of the respective access sent determines the access total amount of client in wireless network.
In one implementation, step 303 can also be：
Judge access control equipment according to all access devices in current period to access control equipment send it is respective
Client is currently accessed total amount in the wireless network that the access information of the client of access is determined, exists with access control equipment
Whether the difference in the wireless network that a upper cycle is determined between the access total amount of client is more than predetermined threshold value；
If so, will then it be currently accessed total amount and be defined as the access total amount of client in wireless network.
Specifically, in order to avoid frequently adjusting the bandwidth threshold of client, access control equipment is only judging itself
The access information of the client of the respective access sent according to all access devices in current period to access control equipment is true
Client is currently accessed total amount in the wireless network made, and from client in the wireless network determined in a upper cycle
Access total amount between difference when being more than predetermined threshold value, can will just be currently accessed total amount and be defined as client in wireless network
Access total amount, and then total amount is currently accessed to what access device sent in current period client in the wireless network determined.
That is, only in the case where the fluctuating range of the access total amount of wireless network clients is larger, access control equipment is
The access total amount of meeting client into access device more new wireless network.The related description in step 202 is may be referred to, herein not
Repeat again.
Step 304, according to outlet bandwidth and access total amount, the bandwidth threshold of client in wireless network is determined, and use
Bandwidth threshold, bandwidth speed limiting is carried out to the client in wireless network.
The detailed process and technique effect of this step may be referred to the step 102 in the bandwidth speed limiting method shown in Fig. 1,
This is repeated no more.
It can be seen that in the bandwidth speed limiting method that the present invention implements offer, access control equipment can be by detecting wireless network
The outlet bandwidth of network and the access total amount for obtaining wireless network clients, calculate the bandwidth threshold of client in wireless network；
In addition, in order to avoid frequently calculating and adjusting the bandwidth threshold of client, influence client and carry out normal network service, access
Control device, just can be to access device more only in the case where the fluctuating range of the access total amount of wireless network clients is larger
The access total amount of client in new wireless network.Can not only avoid the occurrence of due to individual client occurs robbing network speed behavior and shadow
Ring the communication quality of whole wireless network, ensure access wireless network all clients can proper communication, but also can
According to the fluctuation situation of the access total amount of wireless network clients, the wireless network that upgrades in time accesses the bandwidth threshold of client,
Customer experience is more preferably.
In addition, in actual applications, every access information can include address information and the turn-on time of client, address
Information can be specifically MAC Address.
Due to there may be a client sta1, access device A is accessed, also, do not sent out to access device A
In the case of sending disconnection request, access device B is accessed again, now, the client sta1 preserved on access device A access letter
Breath not yet reaches ageing time.So, this results in access device A and access device B has reported visitor to access control equipment
Family end sta1 access information so that access control equipment repeats to count when calculating the access total amount of client of wireless network
Client sta1 has been calculated, have impact on the accuracy of the access total amount of the client calculated.
Therefore, access control equipment needs to investigate the duplicate message in the access information of the client preserved,
To obtain the access total amount of the client of accurate wireless network.
For such case, access control equipment, can for the duplicate message in the access information of the client preserved
Filtered with the turn-on time according to client, step 303 can specifically include：
All access devices of deletion access control equipment management send each in predetermined period to access control equipment
From address information in the access information of the client of access, identical and turn-on time is not access information the latest；
Statistics delete after access information bar number, and the bar number counted is defined as connecing for client in wireless network
Enter total amount.
It should be understood that access information corresponding to more late turn-on time is the effective access information of the client, and
Access information corresponding to turn-on time earlier accesses other access devices or access control equipment before being the client
Access information, it is invalid access information.Access control equipment can delete the invalid access information of the client, avoid in client
The client is computed repeatedly in the access total amount at end.
So, access control equipment is for the access information of the client repeated, when can compare their access
Between, the access information of turn-on time earlier is deleted, ensures the accuracy of the access total amount of the client calculated, Jin Erbao
Demonstrate,prove the accuracy of the bandwidth threshold of the client calculated.
Under practical application scene, access control equipment can be the Fat AP for possessing management function, hereinafter referred to as gateway
AP, access device are the Fat AP, hereinafter referred to as common AP for not possessing management function.Information between gateway A P and common AP is handed over
Control that mutually can be based on WAP and configuration protocol (Control And Provisioning of Wireless
Access Points Protocol Specification, CAPWAP).
In order to facilitate understanding, scene that the equipment for computation bandwidth threshold value is common AP, with reference to gateway A P sides and
Common AP sides illustrate.With reference to figure 4, Fig. 4 is another flow chart of the bandwidth speed limiting method of the embodiment of the present invention, including such as
Lower step：
Step 401, common AP is according to predetermined period, with the forms of broadcasting into wireless network, its in addition to equipment of itself
His equipment, which is sent, finds request.
Wherein, it is found that request carries the flag bit that mark equipment of itself is common AP.
In this step, common AP is sent to its equipment in addition to equipment of itself with the forms of broadcasting and finds request, to connect
Function Access Gateway AP.
In actual applications, predetermined period can be 10 minutes.It was found that request can be specifically Discovery Request
Message, Discovery Request messages are based on CAPWAP agreements, Discovery Request message carrying structure bodies
Vendor TLV, the Vendor TLV include the flag bit that mark equipment of itself is common AP.
Step 402, gateway A P receives the discovery request that common AP is sent, and judges to find whether request carries mark itself
Equipment is common AP flag bit；If it has, then perform step 403.
In this step, gateway A P receives the discovery request from common AP, and then judges whether discovery request comes
From in common AP, specifically, gateway A P judges whether carried in Discovery Request messages including identifying equipment of itself
For the structure Vendor TLV of the flag bit of general mode；Found if it has, then being returned to the common AP for sending discovery request
Response；If it has not, then abandon discovery request.
Step 403, gateway A P sends to common AP and finds response.
In this step, when finding request to carry mark equipment of itself being common AP flag bit, gateway A P is to general
Logical AP, which is sent, finds response.
In actual applications, it can be specifically Discovery Response messages to find to respond, Discovery
Response messages are based on CAPWAP agreements, DiscoveryResponse message carrying structure bodies Vendor TLV, the Vendor
TLV includes the flag bit that mark equipment of itself is gateway A P, in addition to the important information such as gateway A P IP address, software version.
Step 404, common AP receives the discovery response that other Fat AP beyond equipment of itself are returned, and judges to find response
Whether flag bit that mark equipment of itself be gateway A P is carried；If it has, then step 405 is performed, if it has not, then performing step
401。
In this step, common AP receives the discovery response of other equipment return, and judges to find whether response comes from
Gateway A P, specifically, common AP judges whether the structure Vendor TLV that Discovery Response messages carry carry
There is the flag bit that mark equipment of itself is gateway A P, if it has, then association request is sent to gateway A P, should if it has not, then abandoning
It was found that response, returns and perform step 401, rung until receiving and carrying the discovery for identifying the flag bit that equipment of itself is gateway A P
Should.
Step 405, common AP sends association request to gateway A P；
In this step, common AP is it is determined that have found to carry the flag bit that mark equipment of itself is gateway A P in response
When, send association request to gateway A P, it is desirable to access gateway A P.
In actual applications, association request can be Join Request messages, and Join Request messages are based on
CAPWAP agreements.
Step 406, the access request that gateway A P is sent according to the common AP received, accesses the common AP.
In this step, gateway A P performs follow-up access process, makes this common according to the access request from common AP
AP is accessed, and so, the common AP can just be associated with gateway A P, and management is controlled to the common AP by gateway A P, can
With understanding, gateway A P belongs to same wireless network with the common AP associated.
It should be noted that access process may be referred to the AP access process being multiplexed in the prior art in CAPWAP agreements,
Wherein, the Image Download stages skip automatically, and the Configure stages do not issue concrete configuration.
Step 407, after gateway A P takes the business of outlet bandwidth on equipment of itself out of service, to self-management
All common AP send the notice for the outlet for stopping using access control equipment.
In this step, gateway A P begins preparing for the outlet bandwidth to wireless network after detecting that speed-limiting switch is opened
Detected, specifically, the business of outlet bandwidth is first taken on equipment of itself out of service, then, to the institute of self-management
There is the notice that common AP sends the outlet for stopping using access control equipment.
In actual applications, the notice that outlet bandwidth detection prepares can be specifically Configuration Update
Request messages, Configuration Update Request messages are based on CAPWAP agreements, Configuration
Update Request message carrying structure body Vendor TLV, the structure Vendor TLV include being used to identify
Configuration Update Request messages are that outlet bandwidth detects the flag bit for preparing notice message, in addition to speed limit
Flag bit corresponding to switch.
So, after gateway A P detects that speed-limiting switch is opened, speed limit is also carried in the notice issued to common AP
Flag bit corresponding to switch, to inform that common AP opens speed-limiting switch, the step unlatching in limit switch is realized, without again by net
Network keeper intervenes adjusts professional parameter, it becomes possible to reaches and is currently accessed total amount according to client in wireless network, calculates visitor
The bandwidth threshold at family end, and then enter the effect of Mobile state adjustment to the limit of client, avoiding can using preset parameter speed limit
Can be caused to the wasting problem of wireless network port of export bandwidth.
Step 408, common AP stops using the outlet of access control equipment after the notice that gateway A P is sent is received.
In this step, common AP is stopped using after the notice for the outlet bandwidth detection preparation that gateway A P is sent is received
The outlet of access control equipment.Specifically, common AP is according to structure in Configuration Update Request messages
The outlet bandwidth detection that Vendor TLV include prepares the flag bit of notice message, judges the Configuration Update
Request messages are the notice that outlet bandwidth detection prepares, and limit is opened in flag bit determination according to corresponding to speed-limiting switch
Function, then, the outlet of access control equipment is stopped using, in case the detection to the outlet bandwidth of wireless network causes bad shadow
Ring.
Step 409, common AP sends the response for notice to gateway A P.
In this step, common AP is sent for outlet band to gateway A P in the outlet for stopping using access control equipment
The response for the notice that width detection prepares, to inform that gateway A P has carried out the preparation of outlet bandwidth detection.
In actual applications, the response that the notice of preparation is detected for outlet bandwidth can be specifically Configuration
Update Response messages, Configuration Update Response messages are based on CAPWAP agreements.
Step 410, gateway A P is examined after the response that all common AP are returned is received to the outlet bandwidth of wireless network
Survey, obtain the outlet bandwidth of wireless network.
In this step, gateway A P is receiving the sound for the notice prepared for outlet bandwidth detection that all common AP are returned
Ying Hou, it may be determined that all common AP have stopped using the outlet of access control equipment, and now, gateway A P is to wireless network
Outlet bandwidth detected, obtain the outlet bandwidth of wireless network.
Step 411, gateway A P sends the outlet bandwidth of wireless network to all common AP of self-management.
In this step, gateway A P sends the outlet bandwidth of wireless network to all common AP of self-management, so, general
Logical AP can just get the outlet bandwidth of wireless network, and then calculate wireless network access according to the outlet bandwidth of wireless network
The bandwidth threshold of client.
In actual applications, gateway A P can use Configuration Update Request messages to all common
AP sends outlet bandwidth, Configuration Update Request message carrying structure body Vendor TLV, the structure
