Detailed Description

The technical solutions in the embodiments of the present application are described in more detail below.

Referring to fig. 1, a schematic diagram of a system architecture for WLAN management task allocation provided in an embodiment of the present application is shown, where the system includes a server and a plurality of network devices, and the server communicates with the plurality of network devices through a network. The server and the plurality of network devices are described below.

The server is used to provide shared information resources and services for the WLAN and may be a plurality of servers, such as a network management server, a device management server, an authentication server, a location server, and the like.

The plurality of network devices are used for realizing functions of data transmission, data processing and the like. The plurality of network devices may include wireless access points, wireless controllers, switches, firewalls, routers, and the like.

In the embodiment of the present application, the distribution device is responsible for distributing management tasks required by the WLAN. The management tasks required by the WLAN may include configuration management, authentication management, radio frequency tuning, roaming management, wireless location, load balancing, network security monitoring, and other tasks. The distribution device may be a server or one of a plurality of network devices.

Referring to fig. 2, it is a flowchart of another WLAN management task allocation method provided in this embodiment of the present application, where the method may be implemented based on the architecture shown in fig. 1, and an allocation device described below may be a server in the system architecture shown in fig. 1; the network device may be one of the plurality of network devices. The method includes, but is not limited to, the following steps.

S201, the network equipment sends the data of the residual capacity of the network equipment to the distribution equipment.

Wherein the remaining capacity reflects an amount of resources that are free by the network device before the WLAN management task is assigned, such as one or more of a Central Processing Unit (CPU) frequency, a size of free main memory space, and a size of free secondary memory space. The idle resources of the network device before the WLAN management task is allocated may be the idle resources of the network device when the network device is just started, or the idle resources of the network device after some programs/tasks are executed.

The network equipment is the network equipment participating in the election management task. The network devices which do not participate in the election management task do not send data of the remaining capacity of the network devices to the distribution device.

The network device can also send an election instruction to the distribution device, wherein the election instruction comprises an identification of a management task, and the election instruction is used for indicating the type of the management task which needs to participate in election by the network device.

S202, the distribution equipment acquires data of the residual capacity of the plurality of network equipment.

The distribution device acquires the data of the remaining capabilities of the plurality of network devices by receiving the data of the remaining capabilities transmitted by each of the plurality of network devices.

In a possible implementation manner, the allocation device may generate a remaining capacity list according to data of remaining capacities of the plurality of network devices, where the remaining production capacity list includes a correspondence between the network devices and the remaining capacities.

And S203, the distribution equipment selects a first network equipment for bearing the management task from the plurality of network equipment according to the data of the resources required by the running management task and the data of the residual capacity of the plurality of network equipment.

The management task is one of a plurality of management tasks, and the combination of the plurality of management tasks realizes the management of the WLAN. The management tasks may include configuration management, authentication management, radio frequency tuning, roaming management, wireless location, load balancing, network security monitoring, and the like. Conventionally, the management task of the WLAN is entirely assumed by the radio controller, i.e. the management of the WLAN is entirely performed by the radio controller. According to the method and the device, the management task of the WLAN is divided into a plurality of management tasks, and different network devices are selected to undertake the management tasks.

In a possible implementation manner, the allocation device may generate a management task list according to data of resources required to run the plurality of management tasks, where the management task list includes a correspondence between a management task and data of resources required to run the management task.

For example, one management task may also be split into management subtasks. For example, authentication management may be divided into Institute of Electrical and Electronics Engineers (IEEE)802.1X authentication management, Media Access Control (MAC) authentication management, and captive portal (mandatory portal) authentication management. The splitting mode is suitable for networks with higher requirements on stability, and resources consumed by one management task can be further reduced by splitting the management task. The problem that the network equipment bearing the management task is replaced due to the fact that the requirement of resources needed by the management task is improved after a plurality of network equipment are newly added can be solved.

The resources required for running the management task comprise at least one of the lowest frequency of the CPU, the size of the main storage space and the size of the auxiliary storage space. And the minimum frequency of the CPU is the minimum requirement of the CPU frequency required by the normal operation of the management task.

The distribution equipment can acquire data of resources required by the management task by inquiring the pre-stored program configuration of the distribution equipment. The program configuration pre-stored in the distribution equipment includes the kind of the management task required by the WLAN and the data of the resource required for running each management task.

A manner is described below in which the allocation device selects the first network device that undertakes the management task from the plurality of network devices based on data of resources required for running the management task and data of remaining capabilities of the plurality of network devices.

Optionally, the allocating device compares the data of the resources required for running the management task with the data of the remaining capabilities of the plurality of network devices, and selects a network device, of which the data of the remaining capabilities of the plurality of network devices is not less than the data of the resources required for running the management task, as the network device to be determined; and selecting the first network equipment which bears the management task from the network equipment to be determined. The data of the residual capacity of the network equipment is not less than the data representation of the resources required by the running management task, and each item of data in the residual capacity of the network equipment is not less than each corresponding item of data in the resources required by the running management task.

If the network device to be determined is multiple (two or more), there may be multiple ways to select the first network device that undertakes the management task from the network devices to be determined. Three of which are described below.

In a first mode, the allocation device selects any one network device from the network devices to be determined as the first network device.

In a second manner, the allocation device obtains a survey sequence of each item of data in the remaining capabilities of the network devices bearing the management task, sequentially compares each item of data in the remaining capabilities of each network device in the network devices to be determined according to the survey sequence, and selects a first management network device bearing the management task from the network devices to be determined.

The allocation device prestores the investigation sequence of the data items in the remaining capacity of the network device which undertakes the management task, the investigation sequence being determined by the nature of the management task. For example, if a large amount of computation is required to run a first management task, the requirement on the lowest frequency of the CPU is high, then the size of the main storage space is larger, and then the size of the auxiliary storage space is larger, then the investigation sequence of each item of data in the remaining capacity of the network device which undertakes the management task is determined to be the CPU frequency, the size of the idle main storage space, and the size of the idle auxiliary storage space.

Taking the allocation of the first management task as an example, the pending network device includes a third network device and a fourth network device. The data of the remaining capacity of the third network device is the CPU frequency of 3GHZ, the size of 128 megabytes of free main storage space and the size of 30Gbyte of free auxiliary storage space; the remaining capacity of the fourth network device has a data rate of 2GHZ CPU frequency, 146 megabits of free primary storage space and 25 gbytes of free secondary storage space. And sequentially comparing various data in the data of the remaining capacity of the third network equipment and the fourth network equipment in the undetermined network equipment according to the investigation sequence of various data in the remaining capacity of the network equipment bearing the first management task. And if the CPU frequency of the third network equipment is greater than the CPU frequency of the fourth network equipment, selecting the third network equipment as the first network equipment. By the method, the first network equipment which is suitable for operating the network equipment can be matched in the network equipment to be selected according to the resource which is most needed by the management task.

In a third mode, the distribution equipment acquires the calculation weight of each item of data in the residual capacity of the network equipment bearing the management task, and calculates the residual capacity data of the network equipment to be selected according to the calculation weight to obtain the capacity score of each network equipment to be selected in the network equipment to be selected; and taking the network equipment with the highest capability score in the network equipment to be selected as the first network equipment.

The distribution equipment prestores the calculation weight of each item of data in the residual capacity of the network equipment bearing the management task; the computational weight is determined by the nature of the management task. For example, if a large amount of data needs to be stored to run the second management task, and the requirement on the size of the auxiliary storage space is high, and then the size of the main storage space is the minimum frequency of the CPU, it may be determined that the calculation weight of the size of the free auxiliary storage space in each item of data in the remaining capacity of the network device that undertakes the management task is 70%, the calculation weight of the size of the free main storage space is 20%, and the calculation weight of the frequency of the CPU is 10%.

Taking the allocation of the second management task as an example, if the network device to be determined includes a fifth network device and a sixth network device. The data of the remaining capacity of the fifth network device is the size of the idle auxiliary storage space of 30Gbyte, the size of the idle main storage space of 100 Mbytes and the CPU frequency of 3 GHZ; the remaining capacity of the sixth network device is represented by a free auxiliary storage space size of 32Gbyte, a free main storage space size of 120 mb and a CPU frequency of 4 GHZ. And calculating the data of the remaining capacity of the network equipment to be selected according to the calculation weight of each item of data in the remaining capacity of the network equipment bearing the management task to obtain that the capacity score of fifth network equipment in the network equipment to be selected is 41.3, and the capacity score of sixth network equipment is 46.4, so that the sixth network equipment is selected as the first network equipment. By the method, resources required by the management task can be comprehensively considered, and the first network equipment which is suitable for operating the network equipment is matched in the network equipment to be selected.

In addition, if the network device to be determined does not exist in the plurality of network devices, the distribution device may split the management task into a plurality of management subtasks according to a pre-stored splitting program; and the distribution equipment selects a seventh network equipment for bearing one management subtask from the plurality of network equipment according to the data of the resources required for running one management subtask in the plurality of management subtasks and the data of the residual capacity of the plurality of network equipment. The pre-stored splitting program comprises a mode of splitting one management task into a plurality of management subtasks and data of resources required by the plurality of management subtasks. The distribution equipment can acquire the data of the resources required by the management subtasks by inquiring a splitting program prestored in the distribution equipment. The manner in which the allocating device selects the seventh network device that undertakes the management subtask from the plurality of network devices is the same as the manner in which the allocating device selects the first network device that undertakes the management task from the plurality of network devices described above. In the same manner, the distribution apparatus may distribute the remaining management subtasks except the one management subtask among the plurality of management subtasks.

The splitting mode is suitable for the network with smaller initial network size. After the network has access to one or more network devices, the remaining capacity of the network device that undertakes the management task may not satisfy the resources required for running the management task, and the network device that undertakes the management task may be adjusted in this way, so that the management task may run normally.

In an optional implementation manner, after the allocating device selects, according to data of resources required for running a management task and data of remaining capabilities of the plurality of network devices, a first network device that bears the management task from the plurality of network devices, the allocating device refreshes the remaining capability list generated according to the data of the remaining capabilities of the plurality of network devices, that is, the size of a main memory space and the size of an auxiliary memory space required for running the management task are deducted from the remaining capabilities of the first network device.

S204, the distribution equipment sends a distribution instruction to the first network equipment.

Correspondingly, the first network device receives the distribution instruction sent by the distribution device. The allocation instruction comprises an identifier of the management task, and the allocation instruction is used for instructing the first network device to reserve resources required for running the management task and to run the management task. The allocation instruction may further include a program of the management task, and the first network device may execute the management task according to the program of the management task.

S205, the first network device reserves resources required for running the management task according to the allocation instruction and runs the management task.

Since the first network device reserves the resources required for running the management task according to the allocation instruction, the first network device deducts the size of the main memory space and the size of the auxiliary memory space required for running the management task from the remaining capacity of the first network device.

Optionally, before the first network device runs the management task, the method further includes: the first network equipment downloads the functional software of the management task born by the first network equipment from the server or locally activates the function of the management task born by the first network equipment.

S206, the first network equipment sends a management task notification to a wireless access point in the WLAN.

The management task notification includes an identifier of the management task and device information of the first network device, where the device information includes at least one of a device name, a device type, and an Internet Protocol (IP) address of interconnection between networks.

The flow of allocation of a management task by the allocation device is described above. The distribution equipment distributes all management tasks in the task combination for realizing the WLAN management according to the flow. Since the idle resources of a network device are reduced after a management task is assigned to the network device, the management tasks are generally assigned to a plurality of network devices. By distributing the management tasks of the WLAN to the plurality of network devices, the problem of low system reliability caused by the fact that the management tasks are concentrated on the wireless controller is solved; meanwhile, the problem of small network scale caused by limited task bearing amount of the wireless controller is avoided.

Some possibilities are described below which extend on the basis of the embodiment of the method shown in fig. 2.

In an optional manner, the method further includes selecting a standby network device of the first network device that undertakes the management task from the plurality of network devices. The selection of the standby network device is described below.

After the allocating device selects a first network device that bears the management task from the plurality of network devices according to the data of the resources required for running the management task and the data of the remaining capabilities of the plurality of network devices, the allocating device further includes: the allocation device selects a second network device from the at least one network device to serve as a standby of the first network device according to data of resources required for running the management task and data of the residual capacity of the at least one network device except the first network device; and the distribution equipment sends a reservation instruction to the second network equipment, wherein the reservation instruction is used for indicating the second network equipment to reserve the resources required for running the management task. Wherein the second network device may be one or more.

The manner in which the distribution device selects the second network device from the at least one network device to serve as the backup for the first network device may refer to the manner in which the distribution device selects the first network device from the plurality of network devices to undertake the management task described above. By the method, the standby network equipment of the first network equipment can be selected, and meanwhile, the standby network equipment reserves resources, so that the standby network equipment can reserve enough resources required for running the first management task, and can normally run the management task of the first network equipment under the condition that the first network equipment is down, and the reliability of the WLAN is improved.

In the method shown in fig. 2, the allocating device selects a network device that bears the management task from the plurality of network devices by matching the data of the remaining capabilities of the plurality of network devices and the data of the resources required for running the management task until the management task required for the WLAN is allocated. Therefore, the management tasks of the WLAN can be distributed to a plurality of network devices, and the problem of low system reliability caused by the fact that the management tasks are concentrated on the wireless controller is avoided.

Referring to fig. 3, which is a flowchart of another WLAN management task allocation method provided in this embodiment of the present application, the method may be implemented based on the architecture shown in fig. 1, and an allocation device described below may be one network device of a plurality of network devices in the system architecture shown in fig. 1; the network device may be one of the plurality of network devices. The method includes, but is not limited to, the following steps.

S301, the network device sends the data of the residual capacity of the network device to the distribution device. The execution method of this step is the same as the execution method of S201, and is not described herein again.

S302, the distribution equipment acquires the data of the residual capacity of the plurality of network equipment.

The distribution device acquires the data of the residual capacity of the plurality of network devices by receiving the data of the residual capacity sent by the network devices except the distribution device and the data of the residual capacity of the distribution device.

And S303, the distribution equipment selects a first network equipment for bearing the management task from the plurality of network equipment according to the data of the resources required by the management task and the data of the residual capacity of the plurality of network equipment.

The allocation device may obtain the data of the resources required for running the management task by sending an instruction requesting management task data to the server and receiving the data of the resources required for running the management task sent by the server.

The distribution equipment can also acquire data of resources required by the management task by inquiring the program configuration prestored in the distribution equipment.

The execution method of the allocation device selecting the first network device that bears the management task from the plurality of network devices according to the data of the resources required for running the management task and the data of the remaining capabilities of the plurality of network devices is the same as the execution method of S203, and is not described here again.

S304, if the first network device which is selected by the distribution device and bears the management task is the first network device, the distribution device reserves resources required for running the management task, runs the management task, and sends a management task notice to a wireless access point in the WLAN.

Since the allocation device will reserve the resources needed to run the management task, the allocation device will deduct the size of the primary and secondary memory space needed to run the management task from its remaining capacity. Optionally, before the distribution device runs the management task, the method further includes: the distribution equipment downloads the functional software of the management task born by the distribution equipment from the server or locally activates the function of the management task born by the distribution equipment.

Some possibilities are described below which extend on the basis of the embodiment of the method shown in fig. 3.

After the allocating device selects a first network device that bears the management task from the plurality of network devices according to the data of the resources required for running the management task and the data of the remaining capabilities of the plurality of network devices, the allocating device further includes: the allocation device selects a second network device from the at least one network device to serve as a standby of the first network device according to data of resources required for running the management task and data of the residual capacity of the at least one network device except the first network device; and if the standby network equipment of the first network equipment selected by the distribution equipment is self-owned, reserving resources required by running the management task by the distribution equipment.

By the method, the standby network equipment of the first network equipment can be selected, and meanwhile, the standby network equipment reserves resources, so that the standby network equipment can reserve enough resources required for running the first management task, and can normally run the management task of the first network equipment under the condition that the first network equipment is down, and the reliability of the WLAN is improved.

In the method shown in fig. 3, the allocating device selects a network device that is responsible for the management task from the plurality of network devices by matching the data of the remaining capabilities of the plurality of network devices and the data of the resources required for running the management task until the management task required for the WLAN is allocated. Therefore, the management tasks of the WLAN can be distributed to a plurality of network devices, and the problem of low system reliability caused by the fact that the management tasks are concentrated on the wireless controller is avoided.

A specific implementation scenario of the WLAN management task allocation provided by this embodiment is described below. In the implementation scenario, the allocation device is a server, and the plurality of management tasks are respectively a configuration management task, an authentication management task, a radio frequency tuning task, and a roaming management task.

First, a network device sends data of the remaining capabilities of the network device to an allocation device.
