Description

AP management method and device

Technical Field

The present invention relates to the field of wireless network technologies, and in particular, to a method and an apparatus for managing an AP.

Background

With the rapid development of WLAN (Wireless Local Access Network) technology, Wireless networks occupy more and more important positions in people's lives. In order to improve the service quality of the wireless network, the construction of the wireless network is usually implemented in the form of N +1 backup networking. The N +1 backup network includes N primary ACs (Access controllers) and 1 backup AC, for example, N may be less than or equal to 4. Each primary AC may be configured with a preset number of licenses (licenses), so that the AC may be connected to a preset number of APs (Access points) at the same time. The backup AC can share the licenses of the N main ACs, so that the backup AC can be connected with the AP according to all the licenses of the N main ACs. After the AP is connected with the primary AC or the backup AC, the AP may be connected with the terminal to provide a wireless network service for the terminal.

The license of the primary AC shared by the backup ACs results in the total number (which may be referred to as a first total number) of APs to which all ACs (including the primary AC and the backup AC) are connected being greater than the total number (which may be referred to as a second total number) of licenses configured in all the primary ACs, and therefore, the backup AC needs to disconnect some APs. In the prior art, the backup AC may determine the difference between the first total number and the second total number as the number of APs that need to be disconnected (which may be referred to as a target number). Then, the backup AC may randomly select a target number of APs among the APs connected to itself and disconnect the selected target number of APs.

It can be seen that the backup AC only randomly selects a target number of APs, so that the backup AC may disconnect from more APs connected in a unicast manner. After the disconnection, the AP connected in the unicast manner cannot be connected to another AC, so that the AP connected in the unicast manner in the disconnected AP cannot provide a wireless network service for the terminal, thereby reducing the availability of the wireless network.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.

The embodiment of the invention provides a management method and a device of an AP (access point), which can be applied to backup ACs (alternating current controllers) in a target network, wherein the target network can be an N +1 backup network, N represents the number of main ACs in the target network, and the number of the main ACs can be set by technical personnel according to service requirements. Referring to fig. 1, fig. 1 is a block diagram of an N +1 backup networking according to an embodiment of the present invention, which is a possible application scenario. The backup networking comprises: a plurality of primary ACs, a backup AC and a plurality of APs. In fig. 1, the AP1 may be connected to the primary AC1, the AP2 may be connected to the primary AC2, and the AP3 may be connected to the primary AC 3. When the primary AC1 fails, if the AP1 connects in a non-unicast manner, the AP1 may connect with the backup AC to access the wireless network. The backup AC may periodically obtain a total number (which may be referred to as a first total number) of APs to which all ACs (including the primary AC and the backup AC) in the backup networking are connected and a total number (which may be referred to as a second total number) of licenses configured in each primary AC, and if the first total number is greater than the second total number, the backup AC may randomly select a target number of APs from the APs connected to the backup AC, and disconnect the selected target number of APs, where the target number may be a difference between the first total number and the second total number. The disconnected AP may include an AP connected in a unicast manner, or may include an AP connected in a non-unicast manner. If a disconnected AP is an AP connected in a non-unicast manner, the AP may be connected to other ACs in the backup networking after being disconnected, so as to access the wireless network. If a disconnected AP is an AP connected in a unicast manner, the AP cannot be connected to other ACs in the backup networking after being disconnected, that is, cannot access to the wireless network.

Referring to fig. 2, fig. 2 is a flowchart of a method for managing an AP according to an embodiment of the present invention, where the method may be applied to a backup AC in a target network, and the target network may further include a plurality of primary ACs, and the method may include the following steps:

s201: acquiring a first total number of APs connected with the AC in the current target network and a second total number of licenses configured in a plurality of main ACs.

Each primary AC is configured with a preset number of licenses, and the preset number can be set by a technician according to service requirements.

In implementation, when a preset period is reached, the backup AC may obtain the number (i.e., a first total number) of APs connected to all ACs in the target network, and the backup AC may also obtain the number (i.e., a second total number) of licenses configured in each primary AC in the target network, so as to perform subsequent processing. The preset period may be set by a technician based on experience. For example, the backup AC may obtain the number of APs connected to each primary AC and the number of APs connected to the backup AC per se every 10 minutes, so as to obtain a first total number, and meanwhile, the backup AC may obtain the number of licenses configured in each primary AC, so as to obtain a second total number.

S202: if the first total number is larger than the second total number, judging whether a third total number of the APs contained in the first AP set is smaller than a target number; if the third total number is not less than the target number, executing S203; if the third total number is less than the target number, S204 is performed.

The first AP set may be formed by APs connected in a non-unicast manner from among the APs connected to the first AP set, and the target number may be a difference between the first total number and the second total number.

In an implementation, after obtaining the first total number and the second total number, the backup AC may determine whether the first total number is greater than the second total number, and if the first total number is greater than the second total number, the backup AC may further determine whether a third total number of APs included in the first AP set is less than the target number. Specifically, when the backup AC determines that the first total number is greater than the second total number, the backup AC may obtain the number of APs (i.e., a third total number) connected in a non-unicast manner from among the APs currently connected to the backup AC, and then the backup AC may determine whether the third total number is smaller than the target number.

In addition, when the backup AC determines that the first total number is less than or equal to the second total number, the backup AC may not perform any processing.

S203: disconnecting the target number of APs from the first set of APs.

In an implementation, when the backup AC determines that the third total number is greater than or equal to the target number, the backup AC may disconnect from the target number of APs in the first set of APs. Specifically, if the third total number is greater than the target number, the backup AC may determine the target number of APs from the APs connected to the backup AC in the non-unicast manner, and disconnect the APs connected to the determined target number of APs. If the third total number is equal to the target number, the backup AC may directly disconnect from each AP in the first set of APs. The backup AC may determine the target number of APs among the APs connected to the backup AC in the non-unicast manner. For example, the backup AC may randomly select a target number of APs from the APs connected to itself in a non-unicast manner; the backup AC can also determine the target number of APs in the APs connected with the backup AC in a non-unicast mode according to the time sequence of the AP connection.

Optionally, if the third total number is greater than the target number, the backup AC may disconnect the APs with the target number in the first set of APs in the following two ways:

in the first mode, all APs in the first AP set are sequenced according to the sequence of the current terminal connection number from small to large; and disconnecting the connection with the front target number of APs in the first AP set according to the sequencing result.

In implementation, the backup AC may obtain the number of terminals (i.e., the number of terminal connections) connected to each AP in the current first AP set, and then, the backup AC may sort the APs in the first AP set according to the sequence from the small number of terminal connections to the large number of terminal connections. Then, according to the sorting result, the backup AC may determine the number of the previous target APs, and the backup AC may disconnect the determined number of the target APs.

In addition, if the number of terminal connections of multiple APs is the same, the backup AC may determine the identification order of multiple APs according to the identifications of multiple APs. The identification of the AP may be a MAC (Media Access Control) address of the AP. The backup AC may rank the APs with the same number of the multiple terminal connections according to the order from small to large of the identifiers of the APs, or rank the APs with the same number of the multiple terminal connections according to the order from large to small of the identifiers of the APs. The method for ordering the APs with the same number of terminals connected by the backup AC is not limited in the embodiments of the present invention.

For example, the first set of APs includes AP1, AP2, AP3, AP4, AP5, AP6, AP7, and AP8, with a target number of 5. The number of terminal connections of the AP1 is 4, the number of terminal connections of the AP2 is 8, the number of terminal connections of the AP3 is 9, the number of terminal connections of the AP4 is 10, the number of terminal connections of the AP5 is 8, the number of terminal connections of the AP6 is 6, the number of terminal connections of the AP7 is 7, and the number of terminal connections of the AP8 is 8. Identification of AP1 is 1, identification of AP2 is 2, identification of AP3 is 3, identification of AP4 is 4, identification of AP5 is 5, identification of AP6 is 6, identification of AP7 is 7, and identification of AP8 is 8. The backup AC may sequence the APs in the first AP set according to the order from small to large of the number of terminal connections, and the result of sequencing the APs in the first AP set may be: AP1, AP6, AP7, AP2, AP5, AP8, AP3, AP 4.

Therefore, based on the method of the embodiment of the invention, the backup AC can preferentially disconnect the APs with a smaller number of connected terminals in the first AP set, and the influence of disconnection of the backup AC and the APs on the availability of the wireless network can be further reduced.

In a second mode, the processing step of backing up the AC may include:

the method comprises the following steps: sequencing all the APs in the first AP set according to the sequence of the current terminal connection number from small to large;

this step can be referred to the detailed description of the same processing steps in the first embodiment.

Step two: and determining the first target number of APs in the first AP set as first candidate APs according to the sorting result.

In an implementation, the backup AC may determine the first target number of APs as the first candidate AP according to the sorting result. For example, for the example given in manner one above, the backup AC may determine AP1, AP6, AP7, AP2, and AP5 as the first candidate AP.

And step three, determining a third AP set with the terminal connection number smaller than the maximum value of the terminal connection number in the first candidate AP.

In an implementation, after determining the first candidate AP, the backup AC may determine a maximum value of the number of terminal connections (which may be referred to as a first maximum number of connections) according to the number of terminal connections of each AP in the first candidate AP. The backup AC may then determine, among the first candidate APs, a set of APs with a terminal connection number less than the first maximum connection number (i.e., a third set of APs). For example, in the example of step two, the maximum value of the terminal connection number of each AP in the first candidate AP is 8, and the backup AC may determine the first maximum connection number as 8. Then, the backup AC may determine, among the first candidate APs, a third AP set made up of APs (AP1, AP6, and AP7) whose terminal connection number is less than 8.

And step four, selecting a third AP with the fifth total number of terminal connection numbers as the maximum value of the terminal connection numbers in the first candidate AP in the first AP set.

Wherein the fifth total number is a difference between the target number and a number of APs included in the third set of APs.

In an implementation, the backup AC may determine, in the first set of APs, the APs whose terminal connection number is the first maximum connection number, and then, the backup AC may select a fifth total number of APs (i.e., third APs) from the APs whose terminal connection number is determined to be the first maximum connection number. Specifically, the backup AC may randomly select the fifth total number of APs, or may select the first connected fifth total number of APs according to the time sequence of AP connection, which is not limited in the embodiment of the present invention. For example, in the example of step two, the fifth total number is 5-3 ═ 2. The AP with the connection number of 8 (the first maximum connection number) in the first AP set has AP2, AP5, and AP 8. The backup AC may select 2 APs from AP2, AP5, and AP8 as the third AP. Specifically, the backup AC may determine AP2 and AP5 as the third AP, or the backup AC may determine AP5 and AP8 as the third AP, or the backup AC may determine AP2 and AP8 as the third AP.

And step five, disconnecting the connection between each AP contained in the third AP set and the third AP.

In an implementation, after determining the third AP, the backup AC may disconnect the APs included in the third set of APs and the third AP. For example, in the example of step three, the third set of APs includes AP1, AP6, and AP7, and if the backup AC determines AP2 and AP8 as the third AP, the backup AC may disconnect from AP1, AP6, AP7, AP2, and AP 8.

Therefore, based on the method of the embodiment of the invention, the backup AC can preferentially disconnect the APs with less connection numbers with the centralized terminal of the first AP in different modes, and the influence of disconnection of the backup AC and the APs on the availability of the wireless network can be further reduced.

S204: and disconnecting the connection with all the APs contained in the first AP set, and disconnecting the connection with the fourth total number of APs in the second AP set according to the current terminal connection number of all the APs in the second AP set.

The second AP set may be formed by APs connected in a unicast manner from the APs connected to the second AP set, and the fourth total number may be a difference between the target number and the third total number.

In an implementation, when the backup AC determines that the third total number is less than the target number, the backup AC may disconnect from the APs included in the first set of APs. Meanwhile, the backup AC may determine a fourth total number of APs in the second AP set according to the current terminal connection number of each AP in the second AP set, and disconnect the determined fourth total number of APs.

Optionally, the disconnecting, by the backup AC, the fourth total number of APs in the second AP set according to the current terminal connection number of each AP in the second AP set may include the following two ways:

in the first mode, all the APs in the second AP set are sequenced according to the sequence of the current terminal connection number from small to large; and disconnecting the connection with the fourth total number of APs in the second AP set according to the sorting result.

In implementation, the backup AC may obtain the terminal connection number of each AP in the current second AP set, and then, the backup AC may sequence the APs in the second AP set according to the sequence from the small terminal connection number to the large terminal connection number. Then, according to the sorting result, the backup AC may determine the first fourth total number of APs, and the backup AC may disconnect the determined fourth number of APs.

In addition, if the number of terminal connections of multiple APs is the same, the backup AC may determine the identification order of the multiple APs according to the identifications of the multiple APs, and the identifications of the APs may be MAC addresses of the APs. The backup AC may rank the APs with the same number of the multiple terminal connections according to the order from small to large of the identifiers of the APs, or rank the APs with the same number of the multiple terminal connections according to the order from large to small of the identifiers of the APs. The method for ordering the APs with the same number of terminals connected by the backup AC is not limited in the embodiments of the present invention. Specifically, the detailed description of the backup AC for ordering the APs in the first AP set according to the sequence from the small terminal connection number to the large terminal connection number may be referred to.

Therefore, based on the method of the embodiment of the present invention, the backup AC may preferentially disconnect APs with a smaller number of connections to the terminal in the second AP set on the basis of disconnecting the APs included in the first AP set, so as to further reduce the influence of disconnection of the backup AC from the APs on the availability of the wireless network.

In a second mode, the processing step of backing up the AC may include:

the method comprises the following steps: and sequencing the APs in the second AP set according to the sequence of the current terminal connection number from small to large.

And step two, determining the first fourth total number of APs in the second AP set as second candidate APs according to the sorting result.

In an implementation, the backup AC may determine the first fourth total number of APs as the second candidate APs according to the sorting result. For example, the fourth total number may be 10, and the backup AC may sort the APs in the second AP set according to the order from small to large of the number of the terminal connections, and determine the relative order of the APs with the same number of the terminal connections according to the order from small to large of the identifiers of the APs. The backup AC may then determine the top 10 APs in the ranking result as second candidate APs.

And step three, in the second candidate AP, determining a fourth AP set of which the terminal connection number is less than the maximum value of the terminal connection number in the second candidate AP.

In implementation, after determining the second candidate AP, the backup AC may determine a maximum value of the terminal connection numbers (which may be referred to as a second maximum connection number) according to the terminal connection numbers of the APs in the second candidate AP. The backup AC may then determine, among the second candidate APs, a set of APs with the terminal connection number less than the second maximum connection number (i.e., a fourth set of APs).

And step four, selecting a fifth AP with the sixth total number of terminal connection numbers as the maximum value of the terminal connection numbers in the second candidate APs in the second AP set.

Wherein the sixth total number may be a difference between the fourth total number and a number of APs included in the fourth set of APs.

In an implementation, the backup AC may determine, in the second set of APs, the AP whose terminal connection number is the second maximum connection number, and then, the backup AC may select a sixth total number of APs (i.e., a fifth AP) from the APs whose terminal connection number is determined to be the second maximum connection number. Specifically, the backup AC may randomly select the sixth total number of APs, or may select the sixth total number of APs connected first according to the time sequence of AP connection, which is not limited in the embodiment of the present invention.

And step five, disconnecting the AP contained in the fourth AP set and the fifth AP.

In an implementation, after determining the fifth AP, the backup AC may disconnect the APs included in the fourth set of APs and the fifth AP.

In the second to fifth steps in this embodiment, reference may be made to detailed descriptions of examples of the second to fifth steps in the second mode when the backup AC disconnects from the target number of APs in the first AP set.

Therefore, based on the method of the embodiment of the present invention, the backup AC may preferentially disconnect the APs with a smaller number of terminal connections in the second AP set in different ways on the basis of disconnecting the APs included in the first AP set, so as to further reduce the influence of the disconnection of the backup AC from the APs on the availability of the wireless network.

Referring to fig. 3, fig. 3 is a flowchart of an example of a method for managing an AP according to an embodiment of the present invention, where the method may be applied to a backup AC in a target network, where the target network further includes a plurality of active ACs, and the method may include the following steps:
