Background
At present, for an operator, it is difficult to obtain user experience quality of a network video, that is, when a user watches the network video, the operator is difficult to know transmission conditions of the network video on a network link; the traditional network equipment and network management means can detect network indexes such as Round-Trip Time (RTT), jitter, packet loss rate and the like, but for various applications of the mobile internet, the network smoothness does not represent the smoothness of the applications; for example, performance above the Transmission Control Protocol (TCP) layer is not perceived using a conventional internet Protocol (ip) layer network detection scheme.
In order to solve the problem, the conventional common solution is to use a dial testing system to detect the user experience quality of the network video, that is, the application experience quality of the network video is evaluated by using application software at a corresponding place at a corresponding time by a tester. However, this solution has several disadvantages: 1) the application software used is very limited; 2) the application experience quality of the network video can be evaluated only at corresponding places, and when the places are different, the transmission path of the network video is different from the arrival server, so that the scheme is difficult to explain the user experience quality of all the places of the whole network; 3) the user experience quality of the network video can be evaluated only at corresponding time, that is, the evaluation result of the scheme can only reflect the user experience quality of the network video at corresponding time, and cannot reflect the user experience quality of the network video at other time, and particularly, the corresponding user experience quality cannot be obtained aiming at the past time point of the customer complaint.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
First embodiment
Fig. 1 is a flowchart of a method for evaluating quality of experience of network video users according to a first embodiment of the present invention, as shown in fig. 1, the flowchart includes:
step 100: when the user plays the network video, the data volume information of the current network video played by the user is acquired at least once.
Here, when the user needs to play the network video, the user can access the video website.
In this step, the data size information of the current network video played by the user, which is acquired each time, includes: the actual data volume and the required data volume of the network video played by the current user.
Specifically, let i be a natural number greater than or equal to 1, and the actual data volume of the current network video played by the user, which is acquired at the ith time, is: and the actual data volume generated based on the network video played by the user in the ith set time period.
Obviously, in the ith setting time period, the user may receive the video data when playing the network video, and it can be understood that the actual data volume generated based on the network video played by the user in the ith setting time period may be the actual data volume of the video data received when the user plays the network video in the ith setting time period.
Here, various existing implementations may be adopted to obtain the actual data amount of the video data received when the user plays the network video in the ith set time period, and illustratively, the DPI device deployed in the network is adopted to obtain the actual data amount of the video data received when the user plays the network video in the ith set time period.
Specifically, the required data volume of the current network video played by the user, which is acquired at the ith time, is as follows: the required data volume of the network video played by the user in the ith set time period;
illustratively, the calculation formula of the required data volume of the network video played by the user in the ith set time period is as follows: p is S (T1+ T2), where P represents the data amount required by the user to play the network video in the ith set time period, S represents the video bitrate requested by the user to play the network video in the ith set time period, T1 represents the time length of the ith set time period, and T2 represents the pre-configured secondary buffer duration of the network video played by the user.
Here, the secondary cache duration of the network video played by the user is used for representing the cache time required by the video when the corresponding network video is stopped after being played for the first time; generally, the secondary cache duration of the network video played by the user is less than the primary cache duration of the corresponding network video, and the primary cache duration of the network video is used for representing the cache time when the network video starts to play; in this step, the secondary cache duration of the corresponding network video may be configured according to the website where the network video is located.
In this step, the video bitrate requested by the user when playing the network video in the ith setting time period may be obtained in various ways, for example, the DPI device is used to obtain the video bitrate requested by the user when playing the network video in the ith setting time period.
Further, each of the set time periods may be set in the first manner or the second manner, when each of the set time periods is set in the first manner, the starting time point of each of the set time periods is the time point when the user starts playing the network video, and when i is greater than 1, the ending time point of the ith set time period is after the ending time point of the ith-1 time period.
When each set time period is set according to the second manner, when i is greater than 1, the starting time point of the ith set time period is the ending time point of the (i-1) th time period or the time point after the ending time point of the (i-1) th time period, at this time, the time length of each set time period may be the same or different, for example, the time length of each set time period is 5 seconds.
It can be seen that, when each set time period is set in the first manner, when the actual data volume of the network video played by the current user is obtained each time, the data volume needs to be obtained from the time point of starting to play the network video, and thus, higher computing power and storage resources need to be consumed; when each set time period is set in the second mode, if the set time period with a shorter time length is set, the actual data volume in a short time only needs to be acquired when the actual data volume of the current network video played by the user is acquired each time, so that the requirements for computing capacity and storage resources can be reduced.
The following describes an embodiment of setting the actual data volume of the current network video played by the user, which is acquired each time each set time period in the second manner.
When i is equal to 1, the termination time point of the ith set time period is the time point of the ith acquisition of the actual data volume of the network video played by the user; the starting time point of the ith set time period can be the time point when the user starts playing the network video, or the time point after the time point when the user starts playing the network video; the length of the 1 st set time period may be set in advance, for example, the length of the 1 st set time period is 5 seconds.
When i is greater than 1 and the actual data volume acquired from the ith-1 th time is greater than or equal to the required data volume acquired from the ith-1 th time, the actual data volume of the current network video played by the user acquired from the ith time is as follows: the sum of an actual data volume generated based on the network video played by the user in an ith set time period and an excess data volume generated by the network video played by the user in an ith-1 set time period, wherein the excess data volume generated by the network video played by the user in the ith-1 set time period is a difference value obtained by subtracting the required data volume acquired in the ith-1 time from the actual data volume acquired in the ith-1 time; illustratively, the actual data volume obtained at the i-1 st time is A1, the required data volume obtained at the i-1 st time is A2, and the actual data volume generated based on the network video played by the user in the i-th set time period is A3; thus, the amount of redundant data generated by the user playing the network video in the i-1 th set time period is A1-A2, and the actual data amount of the current user playing the network video acquired the i-th time is A3+ (A1-A2).
And when i is greater than 1 and the actual data volume acquired at the (i-1) th time is greater than or equal to the required data volume acquired at the (i-1) th time, the starting time point of the (i) th set time period is the ending time point of the (i-1) th set time period, and the ending time point of the (i) th set time period is the time point of acquiring the actual data volume of the network video played by the user at the (i) th time.
When i is greater than 1 and the actual data volume acquired at the (i-1) th time is less than the required data volume acquired at the (i-1) th time, the actual data volume of the current network video played by the user acquired at the (i) th time is as follows: and the actual data volume generated based on the network video played by the user in the ith set time period.
When i is greater than 1 and the actual data volume acquired at the i-1 th time is less than the required data volume acquired at the i-1 st time, the starting time point of the i-1 th set time period is later than the ending time point of the i-1 th set time period, the sum of the actual data volume acquired at the i-1 st time and the actual data volume generated based on the network video played by the user in the extension time period after the i-1 th set time period is equal to the required data volume acquired at the i-1 st time, the starting time point of the extension time period after the i-1 th set time period is the ending time point of the i-1 th set time period, and the ending time point of the extension time period after the i-1 th set time period is the starting time point of the i-1 th set time period; that is, the time length of the extended period after the i-1 th set period is determined by the actual data amount generated based on the network video played by the user in the extended period after the i-1 th set period, and when the actual data amount generated based on the network video played by the user in the extended period after the i-1 th set period is equal to the difference between the required data amount acquired at the i-1 th time and the actual data amount acquired at the i-1 th time, the extended period after the i-1 th set period reaches the corresponding end time.
Step 101: and counting the times of pause of the network video playing based on the acquired data volume information of the network video played by the user at each time.
The method specifically comprises the following steps: when the actual data volume obtained each time is smaller than the required data volume obtained at the same time, determining that the playing of the network video is blocked for one time; when the actual data volume obtained each time is larger than or equal to the required data volume obtained at the same time, determining that the video playing of the network is not blocked; and counting the times of pause of the network video playing.
It can be seen that when i is greater than 1, and the actual data volume acquired at the i-1 th time is less than the required data volume acquired at the i-1 th time, it indicates that the network video playing is paused for one time; at this time, the redundant data volume generated by playing the network video by the user in the set time period of the (i-1) th time is used as a part of the actual data volume acquired at the ith time.
When i is larger than 1 and the actual data volume acquired at the (i-1) th time is larger than the required data volume acquired at the (i-1) th time, indicating that the video playing of the network is not blocked; after the data volume information of the current network video played by the user is acquired in the (i-1) th time, the set time period is not immediately entered, but the actual data volume of the network video played by the user is continuously acquired in an extended time period after the (i-1) th set time period, when the sum of the actual data volume acquired in the (i-1) th time and the actual data volume generated based on the network video played by the user in the extended time period after the (i-1) th set time period is equal to the required data volume acquired in the (i-1) th time period, the extended time period after the (i-1) th set time period is ended, the set time period is entered, and the actual data volume and the required data volume of the network video played by the user are acquired again.
Particularly, when i is larger than 1 and the actual data volume acquired at the i-1 th time is equal to the required data volume acquired at the i-1 st time, the fact that the video playing of the network is not blocked is indicated; at this time, after the data volume information of the current network video played by the user is acquired in the (i-1) th time, the set time period is entered, and the actual data volume and the required data volume of the network video played by the user are acquired again.
In this step, the counted times of the pause of the network video playing are as follows: and the sum of the times of pause of network video playing corresponding to the data volume information of the network video played by the user obtained each time.
In step 100, data amount information of the network video played by the user is obtained 2 times; the actual data volume obtained in the 1 st time is smaller than the required data volume obtained in the 1 st time, and the fact that the playing of the network video is blocked for one time is determined; the actual data volume obtained in the 2 nd time is more than or equal to the required data volume obtained in the 2 nd time, and the fact that the video playing of the network is not blocked is determined; at this time, the counted number of times of pause of playing the network video is 1.
Step 102: and evaluating the user experience quality of the network video based on the counted times.
In the step, the counted times are used as a basis for evaluating the user experience quality of the network video; the larger the ratio of the counted times to the obtained times of playing the data volume information of the network video by the current user is, the lower the user experience quality of the network video is.
Furthermore, the times of the network video playing occurring pause can be counted for multiple times, that is, after the times of the network video playing occurring pause are counted for any time, the step 100 is returned to, and the step 100 to the step 102 are executed again; it should be noted that, when counting the number of times that the network video is played in a pause state, the counting is performed only based on the data volume information of the network video played by the user, which is acquired each time in the current counting time period, where the current counting time period is a time period from the last counting time point to the current counting time point.
By applying the first embodiment of the method for evaluating the experience quality of the network video user, the data volume information of the current network video played by the user can be obtained at least once when the user plays the network video; counting the times of pause of network video playing based on the acquired data volume information of the network video played by the user at each time; evaluating the user experience quality of the network video based on the counted times; therefore, the method is not limited by the types of the used application software, the video playing places and the video playing time, and can be used for evaluating the user experience quality of any network video, namely, the method has wide applicability in evaluating the user experience quality of the network video. In addition, by analyzing the times of each statistic, the problem of playing the network video complained by the user can be solved through the corresponding user experience quality of the network video obtained through evaluation.
