Description

Technical Field

[0001] The present application belongs to the technical field of communication load balancing, and in particular, relates to a multi-band load balancing method, apparatus, network equipment and computer program product. Background Art

[0002] With the vigorous development of IoT technology, users' homes have generally required multi-STA (Station) access. In this scenario, a single AP needs to handle the network connection and data transmission of multiple devices at the same time, which places extremely high demands on the performance and stability of the AP. Under the traditional WLAN management method, a single AP cannot implement a load balancing strategy, resulting in some frequency bands being overloaded at certain times, while other frequency bands may be idle, which undoubtedly reduces the overall efficiency of the network and user experience. Therefore, on the basis of cost saving, how to implement a dual-band load balancing strategy within a single AP to meet the growing network needs of users has become an important issue that needs to be urgently resolved in the current WLAN technology field. By introducing intra-band load balancing technology, we can allocate network resources more intelligently, improve network stability and throughput, and provide users with better network services.

[0054] The embodiment of the present application provides a multi-band load balancing method for realizing load balancing of multiple target frequency bands of a target AP (Wireless Access Point) to improve the communication performance and communication quality of the target AP. The multi-band load balancing method provided in the present application obtains the total flow of each target frequency band of the target AP in multiple target frequency bands respectively; then obtains the total flow and average flow of all clients connected to the first target frequency band in the multiple target frequency bands; completes the load balancing of the first target frequency band based on the total flow and average flow of all clients connected to the first target frequency band; obtains the total flow and average flow of all clients connected to the second target frequency band in the multiple target frequency bands; completes the load balancing of the second target frequency band based on the total flow and average flow of all clients connected to the second target frequency band, thereby realizing load balancing of multiple frequency bands of the target AP and improving the communication performance and communication quality of the target AP.

[0055] The multi-band load balancing method provided in the embodiment of the present application can be applied to network devices such as routers with AP, mobile phones, tablet computers, vehicle-mounted devices, laptop computers, ultra-mobile personal computers (UMPC), etc. The embodiment of the present application does not impose any restrictions on the specific types of network devices.

[0056] like Figure 1 As shown, the embodiment of the present application provides a multi-band load balancing method, including:

[0057] Step S11, respectively obtaining the total flow of each target frequency band of multiple target frequency bands of the target AP.

[0058] In the application, the target frequency bands include 2G, 5G and 6G. The total traffic of the target frequency band is the actual bandwidth of the communication interface of the target frequency band. The actual bandwidth is less than the maximum bandwidth supported by the communication interface of the target frequency band and is determined by the actual environment.

[0059] Step S12: Obtain the total flow and average flow of all clients connected to the first target frequency band among the multiple target frequency bands.

[0060] Step S13: completing load balancing of the first target frequency band based on the total traffic and average traffic of all clients connected to the first target frequency band.

[0061] In the application, load balancing is performed when the total traffic and average traffic of all clients connected on the first target frequency band respectively meet the preset load balancing conditions of the first target frequency band; when the total traffic and average traffic of all clients connected on the first target frequency band do not meet the preset load balancing conditions of the first target frequency band, the existing communication connection state is maintained.

[0062] Step S14, obtaining the total flow and average flow of all clients connected to the second target frequency band among the multiple target frequency bands.

[0063] In the application, after completing the load balancing of the first target frequency band, the total traffic and average traffic of all clients connected to the second target frequency band are obtained, so as to obtain the latest total traffic and average traffic of all clients connected to the second target frequency band as the load of the first target frequency band is balanced.

[0064] Step S15: completing load balancing of the second target frequency band based on the total traffic and average traffic of all clients connected to the second target frequency band.

[0065] In the application, load balancing is performed when the total traffic and average traffic of all clients connected on the second target frequency band respectively meet the preset load balancing conditions of the second target frequency band; when the total traffic and average traffic of all clients connected on the first target frequency band do not meet the preset load balancing conditions of the first target frequency band, the existing communication connection state is maintained.

[0066] In the application, the target frequency bands include 2G, 5G and 6G, the first target frequency band is 5G, and the second target frequency band is 2G. The first target frequency band and the second target frequency band can be configured according to different usage scenarios. For example, in indoor scenarios (such as bedrooms or living rooms), the first target frequency band is set to 5G and the second target frequency band is set to 2G; in outdoor scenarios, the first target frequency band is set to 2G and the second target frequency band is set to 5G.

[0067] In one embodiment, the step S13, completing the load balancing of the first target frequency band based on the total traffic and average traffic of all clients connected to the first target frequency band, includes:

[0068] Step S131, when the total traffic of the first target frequency band minus the total traffic of all clients connected to the first target frequency band is greater than a preset traffic threshold of the first target frequency band, calculate the average traffic of all clients connected to the first target frequency band.

[0069] In the application, if the total traffic of the first target frequency band minus the total traffic of all clients connected to the first target frequency band is greater than the preset traffic threshold of the first target frequency band, load balancing of the first target frequency band is triggered. The average traffic of all clients connected to the first target frequency band = the total traffic of all clients connected to the first target frequency band ÷ the number of all clients connected to the first target frequency band; the total traffic of all clients connected to the first target frequency band is obtained by adding the traffic of each client among all clients connected to a target frequency band.

[0070] Step S132: for each target client among all clients connected on the first target frequency band, if the traffic of the target client is greater than the average traffic of all clients connected on the first target frequency band, switch the connection frequency band of the target client to the second target frequency band of the target AP.

[0071] In the application, if the traffic of the target client is greater than the average traffic of all clients connected to the first target frequency band, it means that the load brought by the target client to the first target frequency band is greater than the average level of the load brought by all clients on the first target frequency band to the first target frequency band.

[0072] In the application, for each target client among all clients connected on the first target frequency band, if the traffic of the target client is in the first preset number of bits (for example, the first three) of all clients connected on the first target frequency band, the connection frequency band of the target client is switched to the second target frequency band of the target AP.

[0073] In the application, the connection frequency band of the target client is switched to the second target frequency band of the target AP according to the communication protocol (802.11k / v / r protocol) supported by the target client device. When all three protocols are supported, the priority is 802.11v>802.11r>802.11k.

[0074] In one embodiment, the step S15, completing the load balancing of the second target frequency band based on the total traffic and average traffic of all clients connected to the second target frequency band, includes:

[0075] Step S151, when the total traffic of the second target frequency band minus the total traffic of all clients connected to the second target frequency band is greater than the preset traffic threshold of the second target frequency band, calculate the average traffic of all clients connected to the second target frequency band.

[0076] In the application, if the total traffic of the second target frequency band minus the total traffic of all clients connected to the second target frequency band is greater than the preset traffic threshold of the second target frequency band, load balancing of the second target frequency band is triggered. The average traffic of all clients connected to the second target frequency band = the total traffic of all clients connected to the second target frequency band ÷ the number of all clients connected to the second target frequency band; the total traffic of all clients connected to the second target frequency band is obtained by adding the traffic of each client among all clients connected to the two target frequency bands.

[0077] Step S152: For each target multi-frequency client among all clients connected to the second target frequency band, if the traffic of the target multi-frequency client is greater than the average traffic of all clients connected to the second target frequency band, the connection frequency band of the target multi-frequency client is switched to the first target frequency band of the target AP. In an application, if the traffic of the target client is greater than the average traffic of all clients connected to the second target frequency band, it means that the load brought by the target client to the second target frequency band is greater than the average level of the load brought by all clients on the second target frequency band to the second target frequency band.

[0078] In the application, for each target client among all clients connected on the second target frequency band, if the traffic of the target client is in the first preset number of bits (for example, the first three) of all clients connected on the second target frequency band, the connection frequency band of the target client is switched to the second target frequency band of the target AP.

[0079] In one embodiment, the method further comprises:

[0080] Step S161: assigning different load priorities to clients connected to the AP.

[0081] Step S162, when the load priority of the client is higher than the preset priority, cancel the frequency band switching operation for the client in the load balancing process.

[0082] In the application, different load priorities of the client in the target frequency band are assigned to the client according to the communication requirements of the client, and the communication requirements include communication rate priority and communication distance priority. For example, when the first target frequency band is 5G and the second target frequency band is 2G, the communication type of the TV is communication rate priority, and the communication type of the sweeping robot is communication distance priority. The load priority of the TV in the first target frequency band is greater than the first preset priority of the first target frequency band and the load priority of the sweeping robot in the first target frequency band; the load priority of the sweeping robot in the first target frequency band is greater than the first preset priority of the first target frequency band and the load priority of the TV in the first target frequency band.

[0083] like Figure 2 As shown, in one embodiment, the method further includes:

[0084] Step S171, detecting a connection request of a terminal device, wherein the connection request includes a target AP to which the terminal device requests to connect and frequency band support information of the terminal device.

[0085] In the application, when the terminal device connects to the target AP for the first time, it sends a connection request.

[0086] Step S172: when a connection request of a terminal device is detected and the frequency band support information of the terminal device includes a first target frequency band and a second target frequency band, the number of all clients connected to the target AP is obtained.

[0087] In applications, devices such as mobile phones and computers support multiple frequency bands.

[0088] Step S173: If the number of all clients connected to the target AP is less than the total client threshold of the target AP, the number of all clients connected to the first target frequency band of the target AP is obtained.

[0089] In the application, the total client threshold of the target AP is the maximum number of clients supported by the target AP, which is the sum of the maximum number of clients supported by each target frequency band in multiple target frequency bands of the target AP. If the number of all clients connected to the target AP is not less than the total client threshold of the target AP, it means that the target AP no longer supports access to new devices.

[0090] Step S174: if the number of all clients connected to the first target frequency band is less than the first client threshold of the first target frequency band, the terminal device is connected to the first target frequency band as a client.

[0091] Step S175: If the number of all clients connected to the first target frequency band is not less than the first client threshold of the first target frequency band, the number of all clients connected to the second target frequency band of the target AP is obtained.

[0092] Step S176: If the number of all clients connected to the second target frequency band is less than the second client threshold of the second target frequency band, the terminal device is connected to the second target frequency band as a client.

[0093] In the application, a terminal device that is connected to a target AP for the first time is preferentially connected to the first target frequency band of the target AP. When the number of clients connected to the first target frequency band has reached the first client threshold, the terminal device is connected to the second target frequency band.

[0094] In one embodiment, the method further comprises:

[0095] Step S181: when a connection request of a terminal device is detected and the frequency band support information of the terminal device only includes a second target frequency band, the number of all clients connected to the second target frequency band is obtained.

[0096] In applications, some older terminal devices only support one target frequency band, for example, only support the second target frequency band, and therefore need to be connected to the second target frequency band.

[0097] Step S182: If the number of all clients connected to the second target frequency band is less than the second client threshold of the second target frequency band, the terminal device is connected to the second target frequency band as a client.

[0098] Step S183: If the number of all clients connected to the second target frequency band is not less than the second client threshold of the second target frequency band, a connectable AP is selected for the terminal device based on inter-AP load balancing.

[0099] In the application, for terminal devices that only support the second target frequency band, if the number of clients connected to the second target frequency band of the target AP has reached the second client threshold, an AP to which the terminal device can connect can be selected from other APs based on load balancing between APs. For example, an AP with the smallest AP load and the smallest load on the second target frequency band can be selected from other APs for the terminal device.

[0100] In one embodiment, the method further comprises:

[0101] Step S191: If the number of all clients connected to the target AP is not less than the total client threshold of the target AP, select an alternative AP for the terminal device based on inter-AP load balancing.

[0102] In the application, if the number of all clients connected to the target AP reaches the total client threshold of the target AP, it means that all target frequency bands of the target AP have reached the maximum number of clients supported for connection, and the terminal device selects an AP with an AP load from other APs as a replacement AP.

[0103] Step S192: Based on the frequency band support information of the terminal device, the terminal device is connected as a client to the optimal target frequency band among the multiple target frequency bands of the replacement AP.

[0104] In an application, based on the frequency band support information of the terminal device, accessing the terminal device as a client to the optimal target frequency band among multiple target frequency bands of the replacement AP can be performed according to the above steps S11 to S15.

[0105] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0106] The embodiment of the present application also provides a multi-band load balancing device for executing the steps in the multi-band load balancing method embodiment. The multi-band load balancing device can be a virtual device in a network device, which is run by a processor of a first network device, or it can be the network device itself.
