Fig. 2 is a schematic diagram of a wireless network provided in the present application. The AC1-AC2 configures the IP address or domain name of the cloud management platform system. The addresses of the cloud management platform system built in the AC equipment can enable each AC equipment to be automatically connected to the cloud management platform system after being started, and human intervention is not needed.
In the network configuration of the AP11, AP12, AP21, and AP22 devices, a default VLAN interface applies for an IP address in a DHCP client mode, and the AP11, AP12, AP21, and AP22 devices apply for an IP address according to a set address of a gateway device, and may start to establish a TCP connection with a cloud management system.
Various devices of the user (such as various network terminals shown in fig. 2) can manage the terminal 1-terminal 4 which is accessed by the AC1 to control the AP11-AP12 and the terminal 5-terminal 8 which is accessed by the AC2 to control the AP21-AP22 through a Web page of a cloud management platform system.
Fig. 3 is a diagram illustrating an embodiment of controlling average delay based on terminal-applied uplink average delay, where a terminal 1-2 is on two different radio frequencies of an AP11, a terminal 3-4 is on two different radio frequencies of an AP12, a terminal 5-6 is on two different radio frequencies of an AP21, a terminal 7-8 is on two different radio frequencies of an AP22, and each of the terminals 1-8 periodically sends an Action (Action) frame carrying uplink average delay data of an uplink packet applied by the device.
The application extends 802.11 protocol messages, and defines a set value, for example 5, in Element (Element) bytes of an action frame to identify average delay information notification.
The AP11, AP12, AP21, and AP22 receive the management Frame of 802.11, and identify an action Frame based on the value "1101" of the Subtype (Subtype) field of the Frame Control (Frame Control) field. The AP11, AP12, AP21, AP22 distinguish different extended subframes according to bytes of the action frame. The method and the device expand the element bytes of the action frame, and self-define the value of the identifier 'average delay information notification'. After reading the average delay information notification flag of the element byte of the action frame, the AP11, the AP12, the AP21, and the AP22 acquire the uplink average delay of each application of the terminal from the action frame.
In the present application, an element ID field of 1 byte carries an application ID, and an information (information) field of 1 byte carries data of an uplink average delay corresponding to the application ID. As shown in table 1 below
TABLE 1
After receiving the action frame, the AP11, the AP12, the AP21, and the AP22 record the application ID corresponding to the MAC address of each terminal in the source MAC address of the action frame and the uplink average delay of each application.
The AP11 periodically transmits uplink average delay data of each application of different rf terminals 1 and 2 to the AC 1. The AP12 periodically transmits uplink average delay data of each application of the terminal 1 and the terminal 2 on different radio frequencies to the AC 1. And the AC1 receives the uplink average time delay data of each application of the terminal 1-the terminal 4 from the AP 11-the AP12 and sends the uplink average time delay data to the cloud management platform.
The AP21 periodically transmits uplink average delay data of each application of the terminal 5 and the terminal 6 on different radio frequencies to the AC 2. The AP22 periodically transmits uplink average delay data of each application of the terminal 7 and the terminal 8 on different radio frequencies to the AC 2. The AC2 receives uplink average time delay data of each application of the terminals 5 to 8 on different radio frequencies from the AP21 to the AP22, and sends the uplink average time delay data to the cloud management platform.
The cloud management platform summarizes uplink average time delay of each application of the terminals 1 to 8 on different radio frequencies, which is sent by the AC1 and the AC2 respectively, and calculates total average time delay of each application of the terminals 1 to 8 on different radio frequencies according to the counted downlink average time delay data of each application of the terminals 1 to 8 on the radio frequencies 1 and 2.
The cloud management platform collects the summarized data of the average application delay in the wireless network system. In this application, the step of applying the average delay to summarize data at least includes: the uplink average time delay, the downlink average time delay and the total average time delay of each application of a single terminal; uplink average time delay, downlink average time delay and total average time delay of all applications of all terminals on a single radio frequency of a single AP; the uplink average time delay, the downlink average time delay and the total average time delay of each application of all the terminals on all the radio frequencies of a single AP.
And the cloud management platform provides application average delay summarized data for displaying the wireless network system in an application average delay display page. The user can view and diagnose the quality of the wireless network system by applying the average delay display page. The user can optimize the communication quality of the wireless network system aiming at the pertinence.
Aiming at applications needing high-priority processing in a wireless network system, a user can provide an application speed limit page through a cloud management platform to limit the speed of other low-priority applications. And the user inputs a designated application for setting the required speed limit and a designated terminal for running the designated application through the application speed limit page. The terminals running these applications that need to be rate limited may be all terminals on all radio frequencies of all APs or all terminals on all radio frequencies of a single designated AP or all terminals on a single designated radio frequency of a single designated AP or more than one terminal on a single designated radio frequency of a single designated AP. The cloud management platform sends a specified application speed limit instruction to the AC1 or the AC2 of the specified terminal for managing the specified application.
In the application, a certain application running on the terminal 1 and the terminal 2 needs to be limited in speed.
The cloud management platform sends an application speed limit instruction to the AC1 of the management terminal 1 and the terminal 2. The AC1 sends an application speed limit instruction to the AP11, and specifies the application and the terminal which need speed limit; after receiving the application speed limit instruction, the AP11 limits the speed of the application with the speed limit specified on the terminal 1 and the terminal 2, so that the forwarding bandwidths of the uplink message and the downlink message of other applications with high priority on the terminal 1 and the terminal 2 are ensured, and the processing of the application messages with high priority is ensured.
For a terminal in a wireless network that needs high priority processing, such as one or part of high priority terminals that need to guarantee a certain radio frequency of a single AP, the terminal may limit the speed of other low priority terminals on the same radio frequency, or it may need to guarantee all high priority terminals of a certain radio frequency on a single AP and limit the speed of other low priority terminals on the single AP; or the high-priority terminal of one or part of the APs needs to be guaranteed to limit the speed of the low-priority terminal of the rest APs in the network. For example, in the present application, the speed of the terminal 1 needs to be limited to ensure the message forwarding of the terminal 2 with high priority.
A user can input a designated terminal with the speed limit setting requirement through a terminal speed limit page provided by the cloud management platform; the cloud management platform sends a specified terminal speed limit instruction with terminal 1 information to the AC 1. The AC1 sends a terminal speed limit instruction to the AP11, and specifies the terminal 1 needing speed limit. After receiving the speed limit instruction of the designated terminal, the AP11 limits the speed of all applications of the terminal 1, thereby ensuring that the AP11 uses the bandwidth to ensure the forwarding of the uplink message and the downlink message of each application of the terminal 2 with high priority, and ensuring the processing of each application message of the terminal 2.
The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
