Description

AP management method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an AP management method and apparatus.

Background

The number of Access Points (APs) allowed to Access in an Access Controller (AC) is generally limited by the number of licenses (licenses) installed in the AC, for example, if 100 licenses are installed in the AC, the AC allows 100 APs to Access. In a multi-link backup networking environment, taking a dual-link backup networking environment as an example, as shown in fig. 1, AC1 and AC2 are primary and secondary to each other, and when AC1 fails, an AP connected to AC1 may be switched to AC 2. Under the condition, the AC group license sharing technology can be used, and after the AP connected with the AC1 is switched to the AC2, the AC2 does not need to additionally install the license. That is, if 100 licenses are installed in the AC1 and 200 licenses are installed in the AC2, 300 licenses can be shared by the AC1 and the AC 2.

In the above scenario, if the AC1 accesses 150 APs, and the AC2 accesses 200 APs, that is, the AC1 and the AC2 access 350 APs in total, the total number of licenses shared by the AC1 and the AC2 is exceeded, and at this time, the APs exceeding the total number of licenses need to be kicked off the line. Since the number of APs accessed by the AC2 does not exceed the number of licenses installed by itself, but the number of APs accessed by the AC1 exceeds the number of licenses installed by itself, the AC1 randomly kicks off 50 APs exceeding the total number of licenses.

However, there may be an AP executing an important service in the APs that are randomly off-line, and the AP executing the important service cannot provide network connection for the user after being off-line, so that the service cannot be executed. It can be seen that the existing AP offline mechanism has certain risks and defects.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides an AP management method, which is applied to any one AC in an AC group included in a multilink backup networking, wherein the AC group comprises a plurality of ACs which are backed up with each other, and the plurality of ACs share respective installed licenses.

For example, taking the dual link backup networking of fig. 1 as an example, AC1 and AC2 are backup of each other, i.e., AC1 and AC2 belong to one AC group and can share the licenses installed in each.

The AP management method provided in the embodiment of the present application is executed by each AC in an AC group, and as shown in fig. 2, the method specifically includes the following steps:

s201, counting the total amount of online APs connected to the ACs in the AC group every first preset time.

Wherein the total number of online APs connected to an AC in the AC group is the sum of the number of online APs connected to each AC in the AC group.

For example, if the AC group includes the AC1 and the AC2, the number of online APs currently connected to the AC1 is 100, and the number of online APs currently connected to the AC2 is 200, it may be determined that the total number of online APs is 300.

The first preset time period may be set according to an actual requirement, for example, the first preset time period may be 10 minutes, that is, the total amount of the online APs is counted every 10 minutes.

In a first implementation manner, the AC may obtain the number of its own online APs counted by other ACs by communicating with other ACs in the AC group, and further add the number of online APs connected to itself and the number of online APs counted by other ACs, thereby determining the total number of online APs.

For example, the AC1 obtains the number of online APs of the AC2 from the AC2, and then adds the number of online APs of the AC1 itself to the number of online APs of the AC2 to determine the total number of online APs.

In a second implementation, the AC may obtain the total number of online APs from the main AC in the AC group.

That is, each slave AC in the AC group may report the number of its own online APs to the master AC, and the master AC calculates the total number of online APs, and then the slave AC may obtain the total number of online APs from the master AC.

S202, if it is determined that a first difference value between the total amount of the online APs and the total amount of the licenses of the AC group is larger than zero and a second difference value between the number of the online APs connected to the AC group and the number of the licenses installed on the AC group is larger than zero, determining the target number of the APs to be offline according to the first difference value and the second difference value.

The total license amount is the sum of the license amounts of the AC installations in the AC group, for example, if the license amount of the AC1 installation is 100 and the license amount of the AC2 connection is 200, the total license amount of the AC group can be determined to be 300.

In a possible implementation manner, the AC may determine the target number of the APs to be offline when it determines that the first difference is greater than zero and the second difference is greater than zero at one time, and perform the subsequent steps.

In another possible implementation manner, the AC determines the target number of the APs to be offline only when the first difference is determined to be greater than zero and the second difference is determined to be greater than zero for a preset number of consecutive times, and performs the subsequent steps.

As an example, the preset number of times is 3, that is, if the first preset duration is 10 minutes, the total number of online APs counted by one AC at 12:00, 12:10, and 12:20 is 310, 330, and 320, respectively, and is greater than the license total number 300, and the number of online APs counted three times and connected to the AC is 110, 130, and 120, respectively, and is greater than the license number installed by the AC, it may be determined that offline processing needs to be performed on a part of APs.

In another possible implementation manner, the AC determines that the first difference is greater than zero for consecutive preset times, and determines the target number of the APs to be offline if the second difference is greater than zero for the last time of the preset times, and performs the subsequent steps.

For example, if the preset number of times is 3, that is, if the first preset duration is 10 minutes, the total amounts of online APs counted by one AC at 12:00, 12:10, and 12:20 are 310, 330, and 320, respectively, which are all greater than the license total amount 300, and the number 120 of online APs counted at 12:20 and connected to itself is greater than the number 100 of licenses installed, it may be determined that offline processing needs to be performed on a part of APs.

In this embodiment of the application, the target number of the APs to be offline may be determined according to a size relationship between the first difference and the second difference, and specifically includes the following three situations:

in case one, if the first difference is greater than the second difference, the target number of the APs to be offline is determined to be the second difference.

For example, the total amount of online APs is 350 and the total amount of license is 300, i.e., the first difference is 50.

The number of online APs connected to the AC1 is 130 and the number of licenses installed at the AC1 is 100, i.e. for the AC1 the second difference is 30.

It can be seen that the first difference is 50 greater than the second difference 30, although the total amount of the online APs exceeds the license total amount by 50, the number of the online APs connected to the AC1 only exceeds the license number installed by 30, so that the AC can offline 30 APs exceeding the license number installed by itself, that is, the target number of the APs to be offline determined by the AC1 is 30.

In this case, the number of online APs connected to the AC2 is 220, the number of licenses installed in the AC2 is 200, that is, for the AC2, the second difference is 20, and according to the comparison method, the AC2 may offline 20 APs exceeding the number of licenses installed in the AC2, that is, the target number of APs to be offline determined by the AC2 is 20.

It can be understood that if the AC1 goes offline for 30 APs and the AC2 goes offline for 20 APs, the total amount of the online APs in the AC group can be reduced by 50, that is, the total amount of the reduced online APs is 300, and the total amount of the licenses is not exceeded.

And in case two, if the first difference is smaller than the second difference, determining that the target number of the APs to be offline is the first difference.

The number of online APs connected to the AC1 is 170 and the number of licenses installed at the AC1 is 100, i.e. for the AC1 the second difference is 70.

It can be seen that the first difference 50 is smaller than the second difference 70, the number of the online APs connected to the network exceeds the number of the licenses installed in the network by 70, but since the total number of the online APs exceeds the total number of the licenses by only 50, and since the AC1 and the AC2 share 300 licenses, the total number of the online APs is reduced to 300, that is, the AC1 may offline 50 APs exceeding the total number of the licenses, that is, the number of the APs to be offline determined by the AC1 is 50.

In this case, the number of online APs connected to the AC2 is 180, and the number of licenses installed in the AC2 is 200, and it can be seen that the number of online APs connected to the AC2 does not exceed the number of licenses installed in itself, so the AC2 does not need to take offline the AP connected to itself.

And thirdly, if the first difference is equal to the second difference, determining that the target number of the APs waiting for offline is the first difference or the second difference.

The number of online APs connected to the AC1 is 150 and the number of licenses installed at the AC1 is 100, i.e. for the AC1 the second difference is 50.

In this case, since the number of online APs connected to the AC1 is 50 more than the number of licenses installed at the AC1, resulting in 50 more total number of online APs than the total number of licenses, the AC1 may determine that the target number of APs to be offline is 50.

And S203, performing offline processing on the target number of online APs connected to the user according to the acquired flow value of each online AP connected to the user.

Specifically, the target number of online APs with smaller flow values may be selected to perform offline processing according to the order from small to large of the flow values of the online APs connected to the AP.

It can be seen that, by using the method for managing APs provided in this application, an AC may count the total amount of online APs connected to the AC in an AC group once every a first preset time period, and if it is determined that a first difference between the total amount of the online APs and the total amount of licenses of the AC group is greater than zero and a second difference between the number of the online APs connected to the AC group and the number of licenses installed in the AC group is greater than zero, determine the target number of APs to be offline according to the first difference and the second difference, and then perform offline processing on the target number of online APs connected to the AC according to the acquired flow value of each online AP connected to the AC group. Therefore, in the embodiment of the application, when the AC determines that the total amount of the online APs exceeds the license total amount of the AC group and the number of the online APs connected to the AC exceeds the license number installed in the AC group, the online APs to be offline processed are not randomly selected, but the APs are offline processed according to the traffic values of the online APs connected to the AC group.

It can be understood that, in order to enable the AC to perform offline processing on a target number of online APs connected to the AC according to the acquired traffic values of the online APs connected to the AC, statistics needs to be performed on the traffic values of the online APs. The following describes a method for counting the traffic value of the online AP.

And in each statistical period, the AC counts the flow value of each online AP connected with the AC once every second preset time length from the starting time of the statistical period to the current statistical time, and updates the flow value corresponding to each online AP stored in the flow table item.

The statistical period and the second preset time can be set according to actual requirements, and the flow value is the sum of uplink flow and downlink flow between the online AP and the terminal.

Taking the counting period as one day and the second preset time duration as 1 hour as an example, the AC counts the sum of uplink and downlink traffic of each online AP connected to the AC from 00:00 to the current time every other hour from 00:00, for example, at 01:00, the sum of uplink and downlink traffic of each current online AP in the time period of 00:00-01:00 is counted, and at 02:00, the sum of uplink and downlink traffic of each current online AP in the time period of 00:00-02:00 is counted.

As an example, assuming that the online APs to which the AC1 is currently connected have AP1, AP2 and AP3, the traffic table entries corresponding to the AC1 are shown in Table 1.

TABLE 1

AP identification	Flow rate value
		AP1	50M
AP2	100M
		AP3	200M

Assuming that the flow values in the time period of 00:00-01:00 in table 1 are calculated, the flow values in table 1 can be updated after the flow values of all the online APs in the time period of 00:00-02:00 are counted at 02: 00.

It should be noted that table 1 is only an example, and in an actual implementation, the number of online APs connected to the AC and the flow value of each online AP are not limited thereto.

It can be understood that, after one statistical period is finished, the AC deletes the traffic values of the online APs stored in the traffic table entry, and restarts statistics in the next statistical period.

In addition, if there is an AP on the line in the AC, the AC adds the identifier of the AP to the flow table entry, and stores the flow value of the AP in the flow table entry in correspondence with the identifier of the AP after performing subsequent statistics on the flow value of the AP. For example, if at 03:00, it is determined that the online AP connected to AC1 includes AP4 in addition to the APs shown in table 1, then the sum of the uplink and downlink traffic of AP4 from the time of going online to between 03:00 and AC1 will be increased in table 1.

Correspondingly, when the first AP connected to the flow table entry is offline, the flow value of the first AP in the flow table entry is deleted. For example, if at 03:00, it is determined that AP1 in table 1 is in the down state, the row corresponding to AP1 in table 1 is deleted.

Note that, if the AP1 goes offline and goes online again, the traffic value corresponding to the AP1 may be added to table 1, and when the traffic value of the AP1 is counted again, the traffic value from the latest online time of the AP1 to the current counted time is counted.

Optionally, based on the traffic values of the online APs counted in the embodiment of the present application, in step S203, the offline processing is performed on the target number of online APs connected to the offline processing according to the acquired traffic values of the online APs connected to the offline processing, which may specifically be implemented as:

and arranging all online APs in the flow table entry according to the flow value from small to large, and performing offline processing on the previous target number of online APs in the flow table entry according to the arrangement sequence of the online APs.

It can be understood that, after the AC performs offline processing on the target number of online APs, the AC may delete the traffic value corresponding to the offline AP stored in the traffic table entry.

Optionally, after the AP is offline, the AC may delete the traffic value corresponding to the offline AP from the traffic table entry immediately. Or, the AC may delete the traffic value corresponding to the offline AP from the traffic table entry at the next statistical time.
