Background
With the development of communication technology, the network transmission rate is remarkably improved, and particularly, the experience of watching videos on a terminal by a user is improved.

As shown in fig. 2, a method for evaluating network quality provided by an embodiment of the present application includes the following steps.
S101, the server obtains the average download rate and the peak download rate of each terminal in n terminals in a preset time period.
Wherein n is a positive integer greater than 1.
In one possible implementation manner, the server obtains the cumulative download amount and the cumulative download time of each of the n terminals within a preset time period. And the server determines the average download rate of each terminal in the n terminals in the preset time period according to the accumulated download amount and the accumulated download time of each terminal in the n terminals in the preset time period.
The average download rate of each terminal is determined by equation (1):
Vavg＝V/Ttoal (1)
wherein Vavg represents the average download rate, V represents the cumulative download amount, and Ttoal represents the cumulative download time.
Illustratively, the server obtains 9: terminal a1 cumulative download size and cumulative download time for the 00 to 09:01 time period, and terminal a2 cumulative download size and cumulative download time. The cumulative download amount of the terminal a1 is 300 Megabytes (MB), and the cumulative download time is 30 seconds (Second, S). The terminal a2 has a cumulative download volume of 280MB and a cumulative download time of 40S. According to the formula (1), the average download rate of the terminal A1 is 10M/S, and the average download rate of the terminal A2 is 7M/S.
It can be understood that, the server obtains the average download rate and the peak download rate of the plurality of terminals within the preset time period, which can ensure that the data are obtained within the same time period. In addition, the server avoids obtaining the average download rate and the peak download rate of a plurality of terminals in different time periods, thereby eliminating the influence of time on the average download rate and the peak download rate.
S102, the server determines a first parameter set according to the average downloading rate of each terminal in the n terminals.
Wherein the first set of parameters includes n average download rates.
In the embodiment of the present application, the n average download rates are arranged in the first parameter set according to a preset order.
Optionally, the preset sequential arrangement may be divided into two ways.
In the first mode, the n average download rates are arranged in the first parameter set from large to small.
Illustratively, n is 4. The average download rate of the terminal A1 is 10M/S, the average download rate of the terminal A2 is 7M/S, the average download rate of the terminal A3 is 11M/S, and the average download rate of the terminal A4 is 9M/S. The server arranges the average download rates of the 4 terminals in the first parameter set from large to small in the order of 4 average terminals, and then the first parameter set S1 is {11,10,9,7 }.
In the second mode, the n average download rates are arranged in the first parameter set from small to large.
Illustratively, n is 4. The average download rate of the terminal A1 is 10M/S, the average download rate of the terminal A2 is 7M/S, the average download rate of the terminal A3 is 11M/S, and the average download rate of the terminal A4 is 9M/S. The server arranges the average download rates of the 4 terminals in a first parameter set from small to large, wherein the first parameter set S1 is {7,9,10,11 }.
S103, the server determines a second parameter set according to the peak downloading rate of each terminal in the n terminals.
Wherein the second set of parameters includes n peak download rates.
In the embodiment of the present application, the n peak download rates are arranged in the second parameter set according to a preset order.
Optionally, the preset sequential arrangement may be divided into two ways.
In the first mode, the n peak download rates are arranged in the second parameter set from large to small.
Illustratively, n is 4. The peak download rate for terminal A1 was 20M/S, the peak download rate for terminal A2 was 17M/S, the peak download rate for terminal A3 was 15M/S, and the peak download rate for terminal A4 was 25M/S. The server ranks the peak download rates of the 4 terminals in descending order, and the second parameter set S2 is {25,20,17,15 }.
And in the second mode, the n peak download rates are arranged in the second parameter set from large to small.
Illustratively, n is 4. The peak download rate for terminal A1 was 20M/S, the peak download rate for terminal A2 was 17M/S, the peak download rate for terminal A3 was 15M/S, and the peak download rate for terminal A4 was 25M/S. The server ranks the peak download rates of the 4 terminals in descending order, and the second parameter set S2 is {15,17,20,25 }.
It should be noted that, with reference to step S102 and step S103, if the n average download rates are arranged in the second parameter set from large to small, the n peak download rates are arranged in the second parameter set from large to small; if the n average download rates are arranged in the second parameter set from small to large, the n peak download rates are arranged in the second parameter set from small to large.
S104, the server establishes a mapping relation between the first parameter set and the second parameter set.
The mapping relationship between the first parameter set and the second parameter set comprises: the ith average download rate in the first set of parameters corresponds to the ith peak download rate in the second set of parameters.
Illustratively, table 1 shows a mapping relationship between a first parameter set and a second parameter set. Wherein, the first parameter set S1 ═ {11,10,9,7}, and the second parameter set S2 ═ S2 ═ 25,20,17,15 }.
TABLE 1
| First parameter set | Second parameter set |
| 11 | 25 |
| 10 | 20 |
| 9 | 17 |
| 7 | 15 |
And S105, the server determines the ideal peak downloading rate according to the average downloading rate of the target terminal and the mapping relation between the first parameter set and the second parameter set.
And the ideal peak download rate is the peak download rate corresponding to the average download rate of the target terminal in the second parameter set. The target terminal is any one of the n terminals.
Exemplarily, fig. 3 shows parameters of 12 terminals. The horizontal axis of table 1 represents terminals, and the 12 terminals are sorted from small to large according to peak download rates; the vertical axis of table 1 represents the download rate. In table 1, each point in the curve 3 represents a peak download rate corresponding to each terminal, each point in the curve 1 represents an average download rate corresponding to each terminal, and the curve 2 represents an average download rate sorted from small to large, that is, the curve 2 represents a first parameter set.
The point a is the peak download rate of the target terminal, the point B is the average download rate of the target terminal, the point C is the average download rate in the first parameter set equal to the point a, and the point D is the peak download rate obtained according to the mapping relationship between the first parameter set and the second parameter set, that is, the ideal peak download rate.
And S106, the server evaluates the network quality of the target terminal according to the difference between the peak downloading rate of the target terminal and the ideal peak downloading rate.
In one possible implementation, the server sets a preset value. And the server compares the difference value between the peak value download rate of the target terminal and the ideal peak value download rate with a preset value to determine whether the network quality of the target terminal meets the preset requirement. Optionally, the preset value is obtained by multiplying an ideal peak download rate of the target terminal by a preset percentage ratio.
In the embodiment of the present application, the server compares the difference between the peak download rate of the target terminal and the ideal peak download rate with a preset value, and the result can be divided into the following two cases.
In the first situation, if the difference value between the peak download rate of the target terminal and the ideal peak download rate is greater than the preset value, the server determines that the network quality of the target terminal does not meet the preset requirement.
Illustratively, the preset value set by the server is 20% of the ideal peak download rate of the target terminal, the peak download rate of the target terminal is 20M/S, and the ideal peak download rate of the target terminal is 30M/S. The preset value set by the server is 6M/S, the difference value between the peak value download rate of the target terminal and the ideal peak value download rate obtained by the server is 10M/S, the difference value is larger than the preset value, and the server determines that the network quality of the target terminal does not meet the preset requirement.
It should be noted that, after determining that the network quality of the target terminal does not meet the preset requirement, the server may perform active management on the gateway serving the terminal by the operator, for example, old optical modem replacement, bandwidth service awareness management, and the like, so as to improve the overall network capability.
And secondly, if the difference value between the peak value download rate of the target terminal and the ideal peak value download rate is smaller than or equal to a preset value, the server determines that the network quality of the target terminal meets the preset requirement.
Illustratively, the preset value set by the server is 20% of the ideal peak download rate of the target terminal, the peak download rate of the target terminal is 10M/S, and the ideal peak download rate of the target terminal is 15M/S. The preset value set by the server is 5M/S, the difference value between the peak value download rate of the target terminal and the ideal peak value download rate obtained by the server is 5M/S, the difference value is equal to the preset value, and the server determines that the network quality of the target terminal meets the preset requirement.
Based on the above technical solution, in the method for evaluating network quality provided in the embodiment of the present application, the server only needs to obtain the average download rate and the peak download rate of the terminal in the preset time period, and does not need to obtain a plurality of parameters (for example, the initial buffering peak rate, the end-to-end delay E2E RTT, the average rate of the playing stage, the initial buffering delay, the pause duration, and the like). Furthermore, the server determines a first parameter set and a second parameter set, establishes a mapping relation between the first parameter set and the second parameter set, and determines an ideal peak download rate according to the average download rate and the mapping relation of the target terminal; and the server evaluates the network quality of the target terminal according to the difference between the peak downloading rate of the target terminal and the ideal peak downloading rate. In the process, a plurality of parameters (such as initial buffering peak rate, end-to-end delay E2E RTT, playing stage average rate, initial buffering delay, pause duration and the like) are not required to be used for operation, and the operation complexity is effectively reduced. Therefore, the technical scheme of the application can effectively evaluate the network quality of the terminal by means of low complexity.
In order to effectively evaluate the network quality of a terminal by a low-complexity means, embodiments of the present invention provide a method for evaluating the network quality. As shown in fig. 4, the method includes the following steps.
S201-S204 are the same as steps S101-S204, and the specific implementation thereof can refer to the description of steps S101-S104, which is not described herein again.
S205, the server determines an ideal average download rate according to the peak download rate of the target terminal and the mapping relation between the first parameter set and the second parameter set.
The ideal average download rate is the average download rate corresponding to the peak download rate of the target terminal in the first parameter set. The target terminal is any one of the n terminals.
Exemplarily, fig. 5 shows parameters of 12 terminals. The horizontal axis of fig. 5 represents terminals, and the 12 terminals are sorted from small to large according to the average download rate of each terminal; the vertical axis of fig. 5 represents the download rate. In fig. 5, each point in the curve 1 represents the peak download rate corresponding to each terminal, each point in the curve 3 represents the average download rate corresponding to each terminal, and the curve 2 represents the peak download rate sorted from small to large, that is, the curve 2 represents the second parameter set.
In fig. 5, point a is the average download rate of the target terminal, and point B is the peak download rate of the target terminal. The point C is the peak download rate in the second parameter set equal to the point B, and the point D is the average download rate obtained according to the mapping relationship between the first parameter set and the second parameter set, that is, the ideal average download rate.
S206, the server evaluates the network quality of the target terminal according to the difference between the average downloading rate of the target terminal and the ideal average downloading rate.
In one possible implementation, the server sets a preset value. And the server compares the difference value between the average downloading rate of the target terminal and the ideal average downloading rate with a preset value to determine whether the network quality of the target terminal meets the preset requirement. Optionally, the preset value is obtained by multiplying an ideal average download rate of the target terminal by a preset percentage ratio.
In the embodiment of the present application, the server compares the difference between the average download rate of the target terminal and the ideal average download rate with a preset value, and the result can be divided into the following two cases.
In the first situation, if the difference between the average download rate of the target terminal and the ideal average download rate is greater than the preset value, the server determines that the network quality of the target terminal does not meet the preset requirement.
Illustratively, the preset value set by the server is 20% of the ideal average download rate of the target terminal, the average download rate of the target terminal is 8M/S, and the ideal average download rate of the target terminal is 15M/S. The preset value set by the server is 3M/S, the difference value between the average downloading rate of the target terminal and the ideal average downloading rate obtained by the server is 7M/S, the difference value is larger than the preset value, and the server determines that the network quality of the target terminal does not meet the preset requirement.
It should be noted that, after determining that the network quality of the target terminal does not meet the preset requirement, the server may perform active management on the gateway serving the terminal by the operator, for example, old optical modem replacement, bandwidth service awareness management, and the like, so as to improve the overall network capability.
And secondly, if the difference value between the average downloading rate of the target terminal and the ideal average downloading rate is smaller than or equal to a preset value, the server determines that the network quality of the target terminal meets the preset requirement.
Illustratively, the preset value set by the server is 20% of the ideal average download rate of the target terminal, the average download rate of the target terminal is 7M/S, and the ideal average download rate of the target terminal is 8M/S. The preset value set by the server is 1.6M/S, the difference value between the average downloading rate of the target terminal and the ideal average downloading rate obtained by the server is 1M/S, the difference value is smaller than the preset value, and the server determines that the network quality of the target terminal meets the preset requirement.
Based on the above technical solution, in the method for evaluating network quality provided in the embodiment of the present application, the server only needs to obtain the average download rate and the peak download rate of the terminal in the preset time period, and does not need to obtain a plurality of parameters (for example, the initial buffering peak rate, the end-to-end delay E2E RTT, the average rate of the playing stage, the initial buffering delay, the pause duration, and the like). Furthermore, the server determines a first parameter set and a second parameter set, establishes a mapping relation between the first parameter set and the second parameter set, and determines an ideal average download rate according to the peak download rate and the mapping relation of the target terminal; and the server evaluates the network quality of the target terminal according to the difference between the average downloading rate of the target terminal and the ideal average downloading rate. In the process, a plurality of parameters (such as initial buffering peak rate, end-to-end delay E2E RTT, playing stage average rate, initial buffering delay, pause duration and the like) are not required to be used for operation, and the operation complexity is effectively reduced. Therefore, the technical scheme of the application can effectively evaluate the network quality of the terminal by means of low complexity.
In the embodiment of the present application, the server may be divided into the functional modules or the functional units according to the above method examples, for example, each functional module or functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing module.
