Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, WiFi employs a Positive acknowledgement (Positive acknowledgement) mechanism, and all test frames sent by a sending end to a receiving end must be acknowledged by the receiving end with an acknowledgement message (e.g., ACK (acknowledgement character) or BA frame (Block ACK)) to indicate that the test frame is successfully transmitted. If any link fails, and the sender does not receive the response message, the test frame is regarded as lost.
As shown in fig. 1(a), the WiFi protocols before 802.11n, such as 802.11b, 802.11g, 802.11a, only support ACK frames, and require a normal transmission manner of one frame and one acknowledgement; as shown in fig. 1(b), after 802.11n, the transmission efficiency of the MAC layer is improved by modifying the manner of continuously transmitting a plurality of frames and then confirming the plurality of frames at a time, and the transmission of the plurality of frames can save the time of the protocol overhead, thereby achieving the capability of improving the transmission bandwidth.
The invention utilizes the basic principle to actively construct some test frames at the wireless AP side to be sent to the appointed wireless terminal connected to the wireless AP, obtains the packet loss rate transmitted by the WiFi test frame according to the response message (ACK or BA) responded by the appointed wireless terminal, and further calculates the downlink transmission performance from the wireless AP to the wireless terminal from the statistical data.
Example 1
Fig. 2 is a system structure diagram of the wireless network performance testing method in the embodiment of the present invention, in which a server issues a test instruction to a wireless AP, the wireless AP starts active detection, constructs a test frame and sends the test frame to a wireless terminal, and adjusts parameters such as the sending number and the sending rate of the next test frame according to the information of an ACK or BA frame of the wireless terminal, so as to obtain the performance of the wireless terminal.
The invention can send the test instruction to the wireless AP through the server, thereby initiatively initiating the performance detection without the need of coordinating the operation and maintenance personnel to the user environment on site, and greatly reducing the operation and maintenance difficulty; and the server can initiate detection at any time, so that the network problem can be confirmed and analyzed in time, and the network problem of the user can be solved in time.
Example 2
The invention provides a wireless network performance test method, which comprises the following steps:
the wireless AP sends the constructed test frame to a specified wireless terminal connected to the wireless AP at different air interface rates, calculates performance values at different air interface rates according to the received response message responded by the wireless terminal aiming at the test frame, and takes the maximum value of the performance values at different air interface rates as the downlink performance from the wireless AP to the wireless terminal, wherein the test frame is unreachable for application software on the wireless receiving end and reachable for a WiFi bottom driver.
The test frame is unreachable to the application software on the wireless receiving end and reachable to the WiFi bottom layer driver, so that the resource of the wireless terminal is not consumed, the packet can be returned at the driving bottom layer of the wireless terminal, and the packet can not be forwarded to an upper layer.
For example, the test frame may be constructed by the wireless AP using the pktgen tool and sent to the wireless terminal. The pktgen is a high-performance network testing tool located in a Linux kernel layer, is mainly used for testing network drivers and network card equipment, supports multithreading, can generate data packets of random MAC addresses, IP addresses and UDP port numbers, and can meet testing requirements of most network cards and the like. Of course, other tools may be used to construct, or programmed to implement, such test frames.
Generally, the response message may be an ACK (acknowledgement character) or a BA frame (Block ACK).
And the wireless AP calculates performance values at different air interface rates according to the received response message responded by the wireless terminal aiming at the test frame.
For example, the wireless AP sends a certain number of test frames to a designated wireless terminal connected to the wireless AP in unit time, collects statistics related information of response messages of the wireless terminal, adjusts the number of packets sent and the air interface rate according to information such as packet loss rate, and finally obtains the WiFi performance from the wireless AP to the wireless terminal.
For the transmission of the wireless test frame, it is not better that the sent air interface rate is higher, and under the condition of higher physical air interface rate, the wireless terminal may not be able to analyze the frame with high air interface rate due to being far away from the AP, external environment interference, and the like, but the performance may be better at lower air interface rates, so that the performance value at the air interface rate of each gear needs to be obtained, and the actual maximum performance of the terminal can be finally obtained.
Generally speaking, the test instruction is issued by the server to the wireless AP, and the wireless AP executes the test, where the test instruction includes a test policy.
The test strategy comprises the following steps: the wireless AP tests the wireless terminals connected to the wireless AP one by one at a specified specific time or tests a specified wireless terminal immediately; and/or the wireless AP carries out forced test or elegant test on the wireless terminal.
For example, in the embodiment of the present invention, the server initiates a WiFi performance test to the wireless AP according to the relevant policy. For example, the specific strategies are: the server end can appoint a specific time to test all the wireless terminals connected to the wireless AP one by one in the whole network, or test the appointed wireless terminal immediately; in addition, it can also set a forced test or an elegant test, that is, it is judged whether to execute the test on the wireless AP according to the user's service flow, if it is the elegant test, if the current user's service flow is larger, the test is not executed, and the result executed by the server end is returned.

s2, the wireless AP reduces the initial air interface rate by one gear to be used as the current air interface rate;
s3, the wireless AP sends the constructed test frame to a specified wireless terminal connected to the wireless AP at the current air interface rate, and calculates the performance value at the current air interface rate according to the received response message of the wireless terminal to the test frame;

s5, if not, reducing the current air interface rate by one gear to be used as a new current air interface rate, and jumping back to the step S3;
and S6, if yes, taking the performance value under the uplink air interface rate as the downlink performance of the wireless terminal equipment.
Comparing the performance value at the upshifting air interface rate with the performance value at the current gear air interface rate, and if the performance value at the upshifting air interface rate is greater than the performance value at the current air interface rate, immediately obtaining the maximum performance of the terminal as the performance value at the upshifting air interface rate; and if the performance value at the previous air interface rate is not greater than the performance value at the current air interface rate, temporarily taking the performance value at the current air interface rate as the maximum value, reducing the current air interface rate by one level, and calculating the performance value at the new air interface rate again according to the new air interface rate. Thus, the maximum performance value under a certain level of air interface rate is obtained by continuously iterating and circulating.

Example 6
As shown in fig. 6, which is a flowchart of a wireless network performance testing method in an embodiment of the present invention, the method includes:
s101, starting active monitoring by the wireless AP;
s102, initially determining an initial air interface rate; generally, we set the maximum physical air interface rate supported by the wireless terminal as the initial air interface rate;
for example, according to the capability information of the wireless terminal, the number of spatial streams supported (1 × 1 or 2 × 2 or 3 × 3), and the supported modes (11g, 11n, 11ac, etc.), the maximum physical air interface rate supported by the wireless terminal STA is obtained on the wireless AP, and is used as the initial air interface rate;

generally, in order to measure the result quickly, the maximum initial test performance value of the velocity measurement can be determined according to the current air interface rate and the empirical performance value. For example, for wireless terminals with 2 × 2, 20M bandwidth, Long GI, and 2.4G, the air interface rate is 130Mbps, and the actual maximum performance of the big byte tested 1518 is generally about 115 Mbps; the actual maximum performance of the small bytes of the test 88 is generally about 80 Mbps;
and S106, calculating the number of the packages in the test duration according to the current test performance value and the specified test duration.
Generally, the calculation is: n ═ P × t/(B × 8), where N is the number of packets, P is the performance value, t is the preset test duration, and B is the number of bytes for the specified test. For example, if 1518 bytes are specified, the test time is 10s, and the performance value is 100Mbps, it can be calculated that 86345 packets ((100 × 1024)/(1518 × 8) × 10) need to be sent out for these 10 s.
Generally, during initial test, the maximum initial test performance value is adopted, and the test performance value is continuously adjusted in the subsequent test process;
s107, constructing a test frame on the wireless AP, wherein the test frame is inaccessible to application software on a wireless receiving end, and only the test frame needs to be correctly received in a physical layer, so that the target MAC must be the MAC of the wireless terminal; such as: constructing the test frame into a UDP frame, wherein the IP address is a non-receiving end IP, and the UDP source port and the UDP destination port are both 0; or constructing the test frame as a MAC frame, with an ethertype of 0x8899, which is a non-known ethertype (as shown in fig. 7); in addition, the data payload of the test frame contains the ID of the test frame;
s108, recording the corresponding relation between the 802.11 message serial number and the test frame ID;
s109, sending a test frame at a maximum air interface rate according to the specified test time and the calculated message number;
s110, obtaining the result of ACK or BA, obtaining the loss condition of the test frame according to the corresponding relation between the 802.11 message serial number and the test frame ID, and calculating the packet loss rate;
for example, 100 frames with sequence numbers of 0 to 99 are constructed on the wireless AP, the sequence numbers of 802.11 frames corresponding to the frames are N to (N +99), and by counting the ACK or BA, 11 lost frames are obtained, so that the packet loss rate can be calculated to be 11%.
S111, if the packet loss rate is smaller than a set threshold (for example, 1%, adjustment can be performed as required), turning to step S113; if the packet loss rate is greater than a certain threshold, go to step S112;
s112, reducing the current test performance value by one grade to serve as a new current test performance value, and then turning to the step S106 to repeatedly execute the step S106 to the step S111;
s113, taking the performance value under the current test performance value as the performance value under the current air interface rate;
s114, comparing whether the performance value of the air interface rate of the upper level is larger than the performance value of the current air interface rate; if the performance value of the air interface rate of the upshifting is not greater than the performance value of the current air interface rate, then go to step S115; if the performance value of the air interface rate of the upper grade is larger than the performance value of the current air interface rate, go to step S116;
s115, reducing the current air interface rate by one gear to be used as a new current air interface rate, and then turning to the step S105 to repeatedly execute the steps S105 to S114;
and S116, taking the performance value at the uplink air interface rate as the downlink performance from the wireless AP to the wireless terminal.
It should be noted that, as can be understood by those skilled in the art, in the embodiment of the present invention, how to calculate the performance value at the initial air interface rate is not described in detail, the implementation method is the same as that in steps S105 to S113, and corresponding contents are not repeated for simplicity of description.
In the embodiment of the present invention, the maximum physical air interface rate is used as the initial air interface rate, and the air interface rate is downshifted at least once to obtain performance values at different air interface rates, so as to finally obtain the maximum values of the performance values at different air interface rates.
