In order to clearly understand the technical features, objects and effects of the present invention, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. Other embodiments, which can be derived by those skilled in the art from the embodiments of the present invention without inventive step, shall fall within the scope of the present invention.
In the description of the present invention, it should be understood that the numbers themselves, such as "first", "second", etc., are used only for distinguishing the described objects, do not have a sequential or technical meaning, and cannot be understood as defining or implying the importance of the described objects.
Fig. 1 is a schematic flow chart of a method for evaluating the quality of a wired connection network according to a preferred embodiment of the present invention.
As shown in fig. 1, the method includes:
s11: acquiring the actual line length of the connected network cable;
s12: traversing and testing the driving parameters to obtain a critical value of the driving parameters;
s13: acquiring a first supportable wire length corresponding to a preset driving parameter critical value according to the relation between the driving parameter and the supportable wire length;
s14: if the actual line length is larger than the first supportable line length, judging that the network connection quality is good;
s15: and if the actual line length is not larger than the first supportable line length, judging that the network connection quality is poor.
It should be noted that the network port driving signal of the wired communication device usually includes a plurality of driving parameters, such as A, B, C, and each driving parameter has a plurality of adjustable levels, such as 1-16 levels. Before the implementation of the present invention, the driving parameters need to be subjected to a combined traversal test, and a supportable line length obtained by the test under each combination is correspondingly obtained (which may be simply determined according to the link instability or the link failure, when the driving parameter is adjusted to a certain value, and is continuously reduced, the link instability or the link failure is caused, the driving parameter configuration value is a critical value, or may be determined according to the data packet loss rate and/or the data error rate, when the driving parameter is adjusted to a certain value, and is continuously reduced, the data packet loss rate and/or the data error rate is greater than a preset threshold value, the driving parameter configuration value is a critical value), and the finally obtained test result is the corresponding relationship between the driving parameter and the supportable line length. The correspondence is a reference relationship obtained under laboratory conditions, and may be one-dimensional, multidimensional, linear, or nonlinear, and for ease of understanding, the following description will be given by taking one-dimensional as an example. As an example, the correspondence between the driving parameters and the supportable line lengths is shown in table 1.
TABLE 1
| Drive parameter configuration values | A1～A3 | A4～A7 | A8～A11 | A12～A16 |
| Supportable line length | 105m | 115m | 120m | 130m |
When the invention is embodied, firstly, the actual line length L of the connected network line is determined through the CVT line length detection function of the network chip of the wired communication equipment. And then, in the actual application environment, performing a combined traversal test on the driving parameters to find out a critical value An of the driving parameters, so as to obtain a corresponding relation of An-L in the actual application environment. Then, a first supportable line length L1 corresponding to An is found out from the stored relationship between the preset driving parameters and the supportable line length, so as to obtain the corresponding relationship of An-L1 under the laboratory conditions. And finally, comparing the length of the L with that of the L1, wherein if the L is larger than the L1, the user wiring network is superior to the laboratory standard, and the network connection quality is excellent, and if the L is not larger than the L1, the user wiring network is inferior to the laboratory standard, and the network connection quality is poor.
As an example, in an actual application environment, the VCT detection line length is obtained as L90 m, the driving parameter threshold value is obtained as a5, and the supportable line length corresponding to the driving parameter threshold value a5 under a laboratory condition is obtained as L1 m, and since L is less than L1, it can be determined that the network connection quality is poor.
Preferably, when the network connection quality is poor, the diagnosis and positioning of specific problem points such as poor network cable quality, poor network connector quality, or excessive bending of the network cable are performed in combination with the plurality of driving parameters.
As another example, in an actual application environment, the VCT detection line length is 118m, the driving parameter threshold value is a5, and the supportable line length corresponding to the driving parameter threshold value a5 under a laboratory condition is L1 m, which is greater than L1, so that it can be determined that the network connection quality is good.
According to the quality evaluation method for the wired connection network, after the actual line length of the network cable and the supportable line length corresponding to the driving parameter critical value are obtained, the actual line length of the network cable and the supportable line length are compared, the connection quality of the wired connection mode can be judged and evaluated quickly, and when the network connection quality is poor, problems can be diagnosed and positioned, so that the network connection quality is guaranteed.
In a preferred embodiment, the method further comprises:
s16: acquiring a drive parameter default value;
s17: based on the relation between a preset driving parameter and a supportable wire length, acquiring a second supportable wire length corresponding to the preset driving parameter according to the default value of the driving parameter;
s18: when the network connection quality is good, comparing the drive parameter default value with the drive parameter critical value;
s19: if the default value of the driving parameter is not less than the critical value of the driving parameter, acquiring a wire length allowance based on the second supportable wire length and the actual wire length;
s110: and if the drive parameter default value is smaller than the drive parameter critical value, acquiring a drive parameter output value based on the drive parameter critical value.
Specifically, in the wired communication device, a default value a0 of the driving parameter is preset, and after the default value a0 of the driving parameter is obtained, the second supportable wire length L2 corresponding to a0 is found out based on the stored relationship between the preset driving parameter and the supportable wire length. When the network connection quality is good (namely when L is more than L1), comparing A0 with An, if A0 is more than or equal to An, the drive parameter default value can maintain the good connection of the network, and further calculating to obtain a wire length margin L3 which is L2-L; if a0 < An, it means that the default value of the driving parameter cannot be used to connect to the network well, and the output value of the driving parameter needs to be adjusted to be larger than the critical value of the driving parameter, and the wire length margin can be further obtained after the adjustment. After the wire length margin is obtained, it can also be fed back to the user or the wiring person. Or it may also suggest to adjust the driving parameters to higher values, ensuring that the network connection is more stable.
As an example, the default value of the driving parameter is a9, the critical value of the driving parameter is a5, the length of the VCT detection line is L118 m, and the supportable line length of a9 is L2 m 120m, at this time, a9 is greater than a5, then a9 can maintain good connection of the network, and calculate the line length margin L3-L2-L120-118 m 2m, then the network can be timely increased by 2m, the network can also maintain good connection, and the line length margin is intuitively fed back to the user or the wiring personnel in a manner that the network can increase the length. Further, it is also possible to propose to adjust the driving parameters to a12 to a16, where the line length margin L3-L2-L130-118-12 m, and the mesh line increasing length becomes 12 m.
In a preferred embodiment, the performing a traversal test on the driving parameter to obtain a critical value of the driving parameter specifically includes:
s121: sending first test data to test equipment under each drive parameter;
s122: receiving first return data returned by the test equipment, wherein the first return data is data received by the test equipment based on the first test data;
s123: comparing the received data with the first test data, and calculating a first data packet loss rate and/or a first data error rate;
s124: and acquiring the driving parameter critical value according to the calculated first data packet loss rate and/or first data error rate.
Specifically, in this embodiment, the test device does not support the test data sending function and the data statistics function, in this case, the test device only sends the test request to the test device of the opposite end through the local wired communication device, and the test device enters the test mode after receiving the test request. The wire communication equipment at the local end configures the driving parameters as An, the testing equipment at the remote end configures the network chip as a loop mode, and at the moment, the testing equipment receives any testing data and returns the testing data to the wire communication equipment at the local end as it is. And the wired communication equipment at the local terminal counts the received return data, compares the received return data with the sent test data, and calculates the data packet loss rate and/or the data error rate. And after An is traversed, comparing the data packet loss rate and/or the data error rate obtained by the respective tests of A1-A16 with a preset threshold, wherein if the data packet loss rate and/or the data error rate are less than a certain driving parameter configuration value and are greater than the preset threshold, the driving parameter configuration value is the driving parameter critical value.
In the embodiment, the data packet loss rate and/or the data error rate are used as the judgment criteria to determine the driving parameter threshold, so that compared with the case of whether the link is stable, an accurate network connection quality evaluation result can be obtained.
In a preferred embodiment, the performing a traversal test on the driving parameter to obtain a critical value of the driving parameter specifically includes:
s121': sending second test data to the test equipment under each drive parameter;
s122': receiving second return data and third test data returned by the test equipment, wherein the second return data is a second data packet loss rate and/or a second data error rate calculated by the test equipment based on the second test data;
s123': comparing the data received based on the third test data with the third test data, and calculating a third data packet loss rate and/or a third data error rate;
s124': and acquiring the driving parameter critical value according to the calculated second data packet loss rate and/or second data error rate and third data packet loss rate and/or third data error rate.
Specifically, in this embodiment, the test device has a test data transmission function and a data statistics function, in this case, the wired communication device at the home terminal transmits a test request to the test device at the opposite terminal, and the test device enters the test mode after receiving the test request. The wired communication equipment of the local terminal configures the driving parameters into An, sends the configuration parameters to the remote testing equipment before starting to send the testing data, and informs the testing equipment of the format of the testing data to be sent and the number of messages in the data transceiving test to be carried out. After the wired communication device at the home terminal sends a specific test data message to the test device, the test device needs to count the number of the received test data messages, calculate the data packet loss rate and/or the data error rate based on the previously received test data format and the number of the messages, and then return the calculation result to the wired communication device at the home terminal. Meanwhile, the remote testing device also sends testing data, that is, the third testing data, to the local wired communication device with the same driving parameter configuration An, the data does not depend on the received data sent by the wired communication device, but the same testing data format and the same number of messages are sent by the local wired communication device through early notification of the local wired communication device at the beginning, and the local wired communication device further performs data packet loss rate and/or data error rate based on the received data. And after An is traversed, comparing the data packet loss rate and/or the data error rate obtained by the respective tests of A1-A16 with a preset threshold, wherein if the data packet loss rate and/or the data error rate are less than a certain driving parameter configuration value and are greater than the preset threshold, the driving parameter configuration value is the driving parameter critical value.
In the embodiment, the data packet loss rate and/or the data error rate are used as the judgment standard to determine the critical value of the driving parameter, and compared with the method that whether link is stable or not can obtain an accurate network connection quality evaluation result, the test is accurately refined to the two directions of sending and receiving, the two directions do not influence each other, and the network connection quality evaluation result can be obtained more objectively.
It should be noted that the above evaluation process is only one rate mode for the wired communication device, and the present invention can also perform evaluation in different rate modes. For example, network communication is common in 10M, 100M, 1000M, 2.5G, 5G, 10G, etc., and different communication devices may support one or more rate modes. Under different speed modes, adjustable driving parameters, defined and configurable values are different, and corresponding relations of line lengths are different, so that training, learning and evaluation processes of the corresponding relations under different speed modes are independent processes, and network quality evaluation of each speed mode can be realized.
It should be understood that all or part of the processes in the above-mentioned wired connection network quality assessment method can be implemented by a computer program, which can be stored in a computer-readable storage medium and can implement the steps of the above-mentioned wired connection network quality assessment method when being executed by a processor.
