Detailed Description
As shown in fig. 1 to 2, a WIFI bandwidth saturation indication method includes a wireless access device and a plurality of wireless terminals associated therewith; the wireless access equipment sends a bandwidth test instruction to each wireless terminal, and judges whether the bandwidth is saturated according to the wireless link real-time flow acquired by periodic calculation; if the judgment result is negative, repeating the periodic calculation to obtain the real-time flow of the wireless link; and if so, sending a bandwidth saturation instruction to each wireless terminal.
Specifically, the association between the radio access equipment and the radio terminal includes the following steps:
s1, initializing the wireless access equipment and starting an iperf server;
and S2, creating a socket for bandwidth saturation indication and monitoring a specified wireless terminal port through the wireless access equipment.
Further, if the wireless access device monitors the connection of a new wireless terminal, the step S1 to the step S2 are repeated to access the new wireless terminal.
Further, after the wireless access device sends a bandwidth test instruction to each wireless terminal, each wireless terminal establishes an iperf connection with the wireless access device, and the timeout time is specified to be 10 seconds.
Specifically, the radio access device periodically calculates an uplink bandwidth of each radio terminal and reserves a maximum bandwidth as a radio link bandwidth. If the iperf connection is overtime, the wireless access equipment periodically calculates the uplink flow of each wireless terminal, and if the bandwidth occupied by the uplink flow or the wired bandwidth occupied by the sum of the uplink flows of all the wireless terminals on the wireless access equipment side reaches a preset value, the wireless access point sends a bandwidth saturation indication to each wireless terminal. The wireless access equipment and the wireless terminals are respectively provided with LED lamps, and after the wireless access point sends a bandwidth saturation indication to each wireless terminal, the LED lamps flash and give an alarm.
The device based on the WIFI bandwidth saturation indication method comprises the following steps: the initialization module is used for initializing the wireless access equipment and associating a plurality of wireless terminals by starting the iperf server; the monitoring module is used for keeping the association state of the wireless access module and the wireless terminal and controlling the access of a new wireless terminal; and the judging module is used for periodically calculating the uplink bandwidth and the uplink flow of the wireless terminal by the wireless access equipment, judging whether the bandwidth is saturated according to the ratio of the uplink flow to the uplink bandwidth, and correspondingly sending a saturation instruction.
The invention automatically calculates the wireless link bandwidth after the wireless terminal is associated with the wireless access equipment, and then recalculates the bandwidth information of the wireless link between each wireless terminal and the wireless access equipment and stores the bandwidth information in the wireless access equipment when a new wireless terminal is added into the wireless bridge of the wireless access equipment. When the real-time traffic occupies a certain proportion (for example, 80%), the wireless access device and all wireless terminals start to perform LED flashing alarm to indicate that the bandwidth is saturated, and device installation or maintenance personnel can take corresponding measures according to their respective requirements, for example, reduce the number of connected devices behind the wireless terminals, so as to meet the use requirements of different occasions.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
