[0042] It should be understood that the specific embodiments described herein are merely intended to explain the present application, and are not intended to limit the present application.

[0043] In the following description, the suffixes such as "module", "part", or "unit" used to express elements are only for the convenience of explanation of the present application, and have no specific meaning by themselves. Therefore, "module", "part", or "unit" can be mixedly used.

[0044] Figure 1is the first flow chart of the LAN load alarm method of the present application. The embodiment proposes a LAN load alarm method, which comprises:

[0045] S1, obtaining real-time total flow of all the devices hung under all the access points in the LAN by the master device in the LAN according to a preset first period, and judging the size relation between the percentage of the real-time total flow to the bandwidth of the LAN and a preset first flow threshold value;

[0046] S2, generating a first load alarm when the percentage is greater than or equal to the first flow threshold value, and adjusting the first period to a second period, and adjusting the first period to a third period when the percentage is less than the first flow threshold value, wherein the second period is less than the first period, and the third period is greater than the first period.

[0047] In the embodiment, the LAN contains at least two wireless or wired access points, and a flow collection module is configured in the master device of the LAN to perform real-time statistics on the flow of the access devices of the access points in the LAN. Based on this, the flow state of each access point is sent to the flow judgment module of the master device by the flow collection module of the master device after the access devices of the LAN are online, and the flow state is judged by the flow judgment module. If the flow exceeds the threshold value of the access point, or if the flow exceeds the threshold value of the LAN, the user is notified by the flow load alarm module to adjust the access of the device, or to adjust the flow of the device, so as to achieve the purpose of network flow balance, and improve the bandwidth use efficiency in the LAN.

[0048] Optionally, in the embodiment, the preset local area network comprises at least two WiFi access points and one master device, the WiFi access points in the local area network are configured to report real-time traffic of the hung access devices to the master device, wherein the hung access devices comprise hung wired devices and hung wireless devices. Based on this, the traffic collection module of the master device is configured to collect and process the traffic of the access devices in the local area network, and calculate the total traffic value of all the devices hung by each WiFi access point. Further, the percentage of the total traffic value of all the devices hung by the current WiFi access point in the total bandwidth of the local area network is calculated, and the percentage is compared with the preset traffic threshold of the WiFi access point to determine whether the access devices or the device traffic of the current WiFi access point need to be optimized or adjusted. Specifically, the master device determines whether the current WiFi access point needs to be subjected to traffic load alarm according to the calculated percentage, and when the percentage exceeds the traffic threshold, the traffic determination module of the master device sends a message to the traffic load alarm module of the master device to inform the user to adjust the access of the devices or adjust the traffic of the devices.

[0049] Optionally, in the embodiment, the repeating period of the percentage determination operation is set in a backoff manner, for example, the initial traffic determination module of the master device determines the waiting time as T1, the waiting time is T each time, the first waiting time T=T1, if the current percentage exceeds the traffic threshold, the waiting time of the traffic determination module of the master device in the next time is T<T1, if the current percentage does not exceed the traffic threshold, the waiting time of the traffic determination module of the master device in the next time is T>T1, and so on.

[0050] Optionally, in the embodiment, the local area network comprises one master device and at least two WiFi access devices, wherein the master device is configured with a traffic collection module, the WiFi access devices are configured to allow wired devices to access the Internet through network cables and allow wireless devices to access the Internet through WiFi. When the hung access devices of the WiFi access devices access the network, the traffic collection module of the master device is configured to obtain the real-time traffic of any hung access device of any WiFi access device.

[0051] Optionally, in the embodiment, please refer to Figure 6The alarm cycle regulation flowchart is shown. The master device performs statistical processing on the traffic of each device hung under each WiFi access point collected. There are N devices hung under a WiFi access point, the traffic of a single device is recorded as Thn, the real-time total traffic value of all devices hung under each WiFi access point is calculated as TH=Th1+Th2+Th3+…+Thn, the total bandwidth is recorded as B, and the percentage of the total bandwidth occupied by the devices on the current WiFi access point is calculated as P=TH / B according to the traffic value. By comparing the preset traffic threshold Pt of the WiFi access point, it is determined whether the access devices of the current WiFi access point need to be optimized. Specifically, when P>Pt, it is determined that the current WiFi access point needs to perform traffic load alarm, and the user is notified to perform device access or traffic adjustment. When P<=Pt, it is determined that the current WiFi access point does not need to perform traffic load alarm, and the user is not notified to perform device access or traffic adjustment. Further, in this embodiment, the local network load alarm operation repetition period depends on the result of the last alarm. For example, a backoff period mode is adopted, the initial traffic judgment module of the master device determines the waiting time as T1, the waiting time is T each time, the first waiting time T=T1, if the percentage of the total bandwidth occupied by the current WiFi access point exceeds the traffic threshold, then the waiting time of the traffic judgment module of the master device next time is T=T / 2, if the percentage of the total bandwidth occupied by the current WiFi access point does not exceed the traffic threshold, then the waiting time of the traffic judgment module of the master device next time is T=T*2, and so on.

When the percentage is greater than or equal to the first traffic threshold, a first load alarm is generated, and the first period is adjusted to a second period. When the percentage is less than the first traffic threshold, the first period is adjusted to a third period. The second period is less than the first period, and the third period is greater than the first period. The application realizes an adaptive local network load alarm scheme, so that the load of the overall bandwidth of the local network is effectively and timely monitored and adjusted, the utilization rate of the overall bandwidth of the local network is improved, and the balance of the load of the local network is enhanced.
