Description
Technical Field
The present invention relates to the field of device management technologies, and in particular, to a device management method and apparatus.
Background
In a Wireless networking, since an AP (Wireless Access Point) in a conventional AC + AP architecture is a "thin AP," all APs accessing the Wireless networking need to be directly managed and configured by an AC (Access Controller). When the number of APs in the wireless networking is large to a certain extent, a very large load pressure is applied to the AC.
In order to solve the above problems, an AC pool networking model is introduced in the prior art, in which an AC pool is composed of a Central AC (i.e. core layer access controller) and a Local AC (i.e. access layer access controller). The Central AC allocates a Local AC to each AP to be accessed into the group network so as to directly manage the AP through the Local AC, and the Central AC directly manages the Local AC, so that the Central AC indirectly manages the AP. That is, an interface for uniformly configuring and managing each Local AC and the accessed AP may be provided by the Central AC, so as to uniformly manage each Local AC and the accessed AP. Wherein, the APs managed by the AC pool are all thin APs.

and the first Central AC manages each Local AC and the AP accessed to each Local AC according to the activated configuration information.
In a second aspect, an embodiment of the present invention provides an apparatus management device, which is applied to a first core layer access controller Central AC, where the first core layer AC is a standby Central AC selected from multiple access layer access controller Local ACs accessing a second core layer access controller Central AC as a current administrator of networking based on a preset election rule, and the apparatus includes:
the activation unit is used for activating the configuration information which is sent by a second Central AC in advance when detecting that the second core layer access controller Central AC which is a current manager of the networking is invalid;
and the management unit is used for managing each Local AC and the AP accessed to each Local AC according to the activated configuration information.
In the embodiment of the present invention, when the second Central AC as the current manager of the networking fails, the standby management device (i.e. the first Central AC) elected in advance is upgraded to the manager of the networking, and the upgrading step includes: the first Central AC activates the configuration information which is sent by the second Central AC in advance; and managing the Local AC accessed to the second Central AC and the AP accessed to the Local AC according to configuration information. In this way, when the first Central AC fails, the Local AC in the networking and the accessed AP can still be uniformly configured and managed.

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.
In an example of a device management method, in an Access Controller (AC) pool networking model, only one core layer Access control Central AC exists as a networking manager, and the Central AC performs unified configuration management on an Access layer Access Controller Local AC and a wireless Access Point (AP) in networking according to configuration information input by a user.
However, once the Central AC fails, the Local AC and the AP cannot be configured and managed uniformly.
It should be noted that, in the AC pool networking model, it is reasonable that the core layer access controller Central AC may be an access controller with high computing performance, or may be a device, such as a server, a computer, and the like, which is installed with access control software and can implement an access control function.
As shown in fig. 1, a device management method provided in an embodiment of the present invention may include the following steps:
s101: when a first core layer access controller Central AC detects that a second core layer access controller Central AC serving as a current manager of the networking is invalid, activating configuration information sent by the second Central AC in advance; the first Central AC is a standby Central AC which is selected from a plurality of access stratum access controllers Local ACs accessed to the second Central AC based on a preset election rule;
it is understood that in the present embodiment, two types of Central ACs, a first Central AC and a second Central AC, may exist in the AC pool networking model. Before the second Central AC is not invalid, the second Central AC serves as management equipment of the AC pool networking model where the second Central AC is located, and the management equipment in networking where the second Central AC is located is managed; the first Central AC serves as a backup management device for the AC pool networking model and assumes the role of Local AC.
The first Central AC activates the stored configuration information when the second Central AC is failing. Wherein the configuration information comprises: after the first Central AC is elected as a standby management device, the second Central AC is sent to the first Central AC, and is used for configuring information corresponding to the working parameters of each device in the current networking. That is, the configuration information records at least an operating parameter of the wireless access point AP accessing the second Central AC and an operating parameter of the Local AC accessing the second Central AC.
It should be noted that when the second Central AC is operating normally, a communication tunnel is established between the second Central AC and each Local AC, and when the Local AC detects that the communication tunnel with the second Central AC is disconnected and cannot be established again, it may be determined that the second Central AC is failed.
It should be further noted that before the second Central AC fails, the second Central AC manages the Local AC and the wireless access point AP in the networking according to the configuration information, and this management manner is the prior art and will not be described in detail herein. In addition, the Local AC and the Central AC in the networking may be the same type of AC device, but the roles assumed in the networking are different.
S102: and the first Central AC manages each Local AC and the AP accessed to each Local AC according to the activated configuration information.
It can be understood that the first Central AC may implement direct management of the Local AC and indirect management of the AP accessing the Local AC by sending configuration information to each Local AC.
In one implementation, the first Central AC may send configuration information to each Local AC through a pre-constructed backup tunnel. The backup tunnel is pre-constructed and the first Central AC and Local ACs may be used for communication channels to transmit information.
In another implementation, before the first Central AC manages each Local AC and the AP accessing each Local AC according to the activated configuration information, a target tunnel between the first Central AC and each Local AC in the group network may be established; therefore, the first Central AC can manage each Local AC and the AP accessing each Local AC through the target tunnel according to the activated configuration information. For the sake of clear layout, the manner of establishing the target tunnel is described in detail later.
In addition, the configuration information that the first Central AC transmits to each Local AC may be: all configuration information obtained by the first Central AC. When any Local AC receives all the configuration information, the configuration information required by the Local AC is obtained from all the configuration information. Of course, the configuration information sent by the first Central AC to each Local AC may also be: it is reasonable that the configuration information required by each Local AC, i.e., the first Central AC can transmit the configuration information required by each Local AC to each Local AC, respectively.
It should be noted that it is reasonable to transmit the configuration information to each Local AC when the first Central AC detects that the configuration information is changed.
It should be noted that, when there is a new AP to access the group network, the first Central AC may designate a Local AC for the new AP, so as to directly manage the new AP by using the designated Local AC.
In the embodiment of the present invention, when the second Central AC as the current manager of the networking fails, the standby management device (i.e. the first Central AC) elected in advance is upgraded to the manager of the networking, and the upgrading step includes: the first Central AC activates the configuration information which is sent by the second Central AC in advance; and managing the Local AC accessed to the second Central AC and the AP accessed to the Local AC according to configuration information. In this way, when the first Central AC fails, the Local AC in the networking and the accessed AP can still be uniformly configured and managed.
The following further describes a manner of establishing the target tunnel in the embodiment of the present invention.
In one implementation, the method for establishing the target tunnel between the first Central AC and each Local AC in the networking includes: when the first Central AC receives the access request sent by each Local AC of the current networking, the first Central AC establishes a target tunnel with each Local AC according to the access request, so that each Local AC actively requests to establish the target tunnel with the first Central AC.
The access request is a request sent by each Local AC to the first Central AC according to the identification information of the first Central AC sent by the second Central AC in advance after the second Central AC is detected to be out of service. The second Central AC may send the identification information of the first Central AC in advance in a broadcast manner.
For example, when the second Central AC elects the standby Central AC (i.e., the first Central AC), the second Central AC broadcasts the identification information of the standby Central AC to each Local AC in the current network; each Local AC sends an access request to the first Central AC according to the identification information of the first Central AC broadcast by the second Central AC in advance; after receiving the access request, the first Central AC establishes a connection (i.e., a target tunnel) with each Local AC. Any communication protocol capable of establishing a target tunnel between a Central AC and a Local AC in the prior art may be used to establish the target tunnel between the first Central AC and each Local AC, which is not described in detail herein.
It should be noted that the identification information is identification information that can uniquely identify the first Central AC, for example, a Media Access Control (MAC) address of the first Central AC, but is not limited thereto.
In another implementation, the method for establishing the target tunnel between the first Central AC and each Local AC in the networking includes: the first Central AC sends a connection establishment request to each Local AC, and establishes a target tunnel with each Local AC based on the connection establishment request. In this implementation, the first Central AC is caused to proactively request establishment of a target tunnel with each Local AC.
In an embodiment of the present invention, the manner for the first Central AC to activate the configuration information that is sent by the second Central AC in advance may include the following steps:
extracting configuration information sent by a second Central AC in advance from a configuration library which is not validated by the first Central AC;
and calling the extracted configuration information into the memory for operation.
It is to be understood that the first Central AC, upon receiving the configuration information sent by the second Central AC, stores the configuration information in the configuration repository that is not in effect; activating the configuration information when the second Central AC fails. Wherein activating the configuration information means: and extracting the configuration information from the configuration library which is not in effect, and calling the configuration information to an internal memory for operation so as to activate the configuration information.
The configuration library which is not in effect stores files such as binary files or text files, and the files stored in the configuration library which is not in effect do not run in the memory.
In another embodiment of the present invention, the manner of the second Central AC electing the standby Central AC based on the preset election rule may include:
and the second Central AC elects a standby Central AC based on the access sequence of the Local AC accessing the second Central AC.
For example, the second Central AC may select the Local AC that is first accessed to the second Central AC as the standby Central AC, and update a record about the standby device, where the record records at least the identification information of the standby Central AC. Of course, it is reasonable to choose the Local AC in any access order as the standby Central AC.
In another embodiment of the present invention, the manner of selecting the standby Central AC by the second Central AC based on the preset selection rule may further include:
and the second Central AC elects a standby Central AC based on the AP load capacity of the Local AC accessed to the second Central AC.
It is to be understood that the AP load capacity of the Local AC may include at least one of a remaining AP load capacity of the Local AC and a total AP load capacity of the Local AC.
For example, the standby Central AC may be reselected by:
in one implementation, when each new Local AC accesses the second Central AC, the remaining AP load capacity of the current standby Central AC is queried, and if the remaining AP load capacity is less than 50% of the total AP load capacity of the current standby Central AC, the Local AC with the largest remaining AP load capacity in the current network is used as the standby Central AC.
In another implementation, when each new Local AC accesses the second Central AC, the total AP load capacity of the current standby Central AC is queried, and if the total AP load capacity of the current standby Central AC is less than 50% of the total AP load capacity of the newly accessed Local AC, the Local AC with the most AP load capacity remaining in the current network is used as the standby Central AC.
In another implementation, when it is detected that an AP in the networking accesses the networking by accessing the standby Central AC, querying a remaining AP load capacity of the current standby Central AC, and if the remaining AP load capacity is less than 50% of a total AP load capacity of the current standby Central AC and the remaining AP load capacity exists in the current networking and is greater than 1 time of a Local AC greater than the remaining AP load capacity of the standby Central AC, taking the Local AC with the largest remaining AP load capacity in the current networking as the standby Central AC.
In yet another implementation, when it is detected that a standby Central AC of the networking exits the networking, the Local AC currently having the largest remaining AP load capacity is taken as the standby Central AC.
It should be noted that the second Central AC may also be selected as the spare Central AC by combining the two methods for selecting the spare Central AC.
For example, the second Central AC elects the first Local AC accessed to the second Central AC as the backup Central AC, and reselects the backup Central AC based on the AP load capacity of the accessed Local ACs when the second Central AC detects at least two Local ACs accessed.
It is emphasized that after each update of the standby Central AC, the second Central AC needs to broadcast the identification information of the new standby Central AC to all devices in the networking and send configuration information to the new standby Central AC. After choosing a new standby Central AC, the original standby Central AC deletes the configuration information received from the second Central AC.
In another embodiment of the present invention, after the first Central AC activates the configuration information that is sent by the second Central AC in advance, the method may further include:
the first Central AC manages the APs loaded by itself.
It can be understood that the first Central AC is responsible for directly managing the AP before being upgraded to the administrator of the networking, and the loaded AP can still be directly managed after the first Central AC is upgraded to the administrator.
The device management method provided by the embodiment of the present invention is further described with reference to fig. 2.
As shown in fig. 2, a certain AC pool networking model includes a core layer access controller, an access layer access controller 1, an access layer access controller 2, an access layer access controller 3, and a wireless access point 1. Wherein the wireless access point 1 may be connected to any access stratum access controller via the internet. Wherein the access stratum access controller 1 is elected as a standby core layer access controller.
When the core layer access controller in the AC pool networking model fails, the original access layer access controller is upgraded to a new core layer access controller 1, and the access layer access controller 2, the access layer access controller 3 and the wireless access point 1 are managed. The wireless access point 1 may be connected to any access layer access controller via the internet, or may be connected to the new core layer access controller via the internet.
Corresponding to the foregoing method embodiment, an embodiment of the present invention further provides an apparatus management device, which is applied to a first core layer access controller Central AC, where the first core layer AC is a standby Central AC selected from multiple access layer access controllers Local ACs accessing a second core layer AC, based on a preset election rule, and the apparatus may include:
