Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a first specific implementation manner of a method for acquiring a network download speed, and referring to fig. 1, the method specifically includes the following steps:
step 100: two data files are simultaneously and respectively downloaded in a target network by double threads.
In step 100, in order to effectively reduce the problem of inaccurate speed measurement result caused by network fluctuation, the network downloading speed obtaining device simultaneously controls the first terminal to download two data files in the second terminal in the target network by using a dual thread (LWP), so that the accuracy of the speed measurement result can be effectively improved because the probability that the two data files have the same network fluctuation at the same time point is very low, that is, the thread TH1 in the first terminal is used for downloading the data file F1, the thread TH2 is used for downloading the data file F2, and the thread TH1 and the thread TH2 start downloading at the same time. It will be appreciated that the first and second terminals may each be a computer or server and that data file F1 and data file F2 are both stored in the second terminal; the data files F1 and F2 may be audio, video, text, etc. and the types of the data files F1 and F2 may be the same or different in this embodiment. And the protocol used by thread TH1 and thread TH2 is downloaded via the uniform Resource locator URL (Uniform Resource locator) of the Hypertext Transfer protocol HTTP (HyperText Transfer protocol).
Step 200: and periodically acquiring the download data amount of each thread in each time period during the respective download data file period, wherein the time length of each time period is the same.
In step 200, the obtaining device of the network download speed periodically obtains the download data amount of each thread in each time period during the respective download data file at the same time interval, and specifically, a timer1 and a timer2 may be respectively set in the thread TH1 and the thread TH 2; such that timer1 and timer2 are used simultaneously and respectively to record the times at which the start of data download and the end of data download by thread TH1 and thread TH2 occur. The duration of the time periods for recording data of the thread TH1 and the thread TH2 is the same, and is equal to the time interval between every two recording actions, so as to ensure that the downloaded data volume of the thread TH1 and the thread TH2 of each time period can be merged subsequently in the time periods with the same duration and time nodes.
For example, if the time interval is set to 0.1 second according to a specific network environment, when data downloading is started at the same time of thread TH1 and thread TH2, timer1 and timer2 are controlled to start timing respectively, and the amount of data downloaded between 0.1 second before the current time and the current time by thread TH1 and thread TH2 is recorded every 0.1 second.
It can be understood that, the thread TH1 and the thread TH2 start data downloading at the same time, and when the thread TH1 and the thread TH2 start data downloading at the same time, the timer1 and the timer2 start timing respectively and simultaneously, but due to the influence of line transmission fluctuation and the difference of data sizes in the data file F1 and the data file F2, the thread TH1 and the thread TH2 may not finish data downloading to the data file F1 and the data file F2 respectively at the same time point, so that the timer1 stops timing when the thread TH1 finishes downloading to the data file F1; when the thread TH2 finishes downloading the data file F2, the timer2 stops counting.
Step 300: and summing the download data volume of each thread in each time period to obtain the total download data volume of the double threads in each time period.
In step 300, the obtaining device of the network download speed sums the download data amount of each thread in each time period to obtain the total download data amount of the dual threads in each time period.
For example, the timer1 and the timer2 start to count at 9:00, wherein the timer1 stops counting when the thread TH1 finishes downloading the data file F1 at 9:10, the timer2 stops counting when the thread TH2 finishes downloading the data file F2 at 9:15, and the time interval and the time period are both 1 minute; selecting the data volume downloaded by the thread TH1 and the thread TH2 recorded between 9:00 and 9:10 for processing, and since the time interval and the time period are all 1 minute, 10 time periods are included between 9:00 and 9:10, adding the data volume downloaded by the thread TH1 and the thread TH2 in each of the 10 time periods to obtain total download data volumes e1, e2, … e10 of the thread TH1 and the thread TH2 in each of the 10 time periods, wherein the total download data volumes of the thread TH1 and the thread TH2 in each of the first time period to the tenth time period in turn are e1, e2, … e 10.
Step 400: and acquiring the standard downloading speed of the target network according to the total amount of the downloaded data of the double threads in each time period.
In step 400, the network download speed obtaining device obtains the standard download speed of the target network according to the total amount of the downloaded data of the dual threads in each time period. Specifically, the total download data amount of the dual threads in each time period may be summed and then averaged, and the obtained average is used as the standard download speed of the target network.
As can be seen from the above description, the method for acquiring network download speed provided in the embodiment of the present invention downloads two files through two threads, and determines the standard download speed of the target network according to the data recording result in the downloading process of the two threads, so as to effectively solve the problem of inaccurate speed measurement result caused by network fluctuation, ensure the accuracy of the speed measurement result, and ensure a reliable and fast speed measurement process.
A second embodiment of the present invention provides a second specific implementation manner of the method for acquiring a network download speed, and referring to fig. 2, the method for acquiring a network download speed further includes the following steps:
between the above steps 300 and 400, the following steps a01 and a02 are performed;
step A01: and generating a download data speed statistical table according to the total download data amount of the double threads in each time period, wherein the download data speed statistical table comprises a one-to-one mapping relation between each time period and the total download data amount of the double threads in each time period.
In step a01, the obtaining device of the network download speed generates a download data speed statistical table according to the total amount of download data of the dual threads in each time period. For example, the download data speed statistical table stores 10 time periods, and further stores total download data amounts e1, e2, … e10 of the thread TH1 and the thread TH2 in each of the 10 time periods, where the e1, e2, … e10 are total download data amounts of the thread TH1 and the thread TH2 in the first time period to the tenth time period in sequence, as shown in table 1:
TABLE 1
| First time period | e1 |
| A second time period | e2 |
| … | … |
| The tenth time period | e10 |
Step A02: and screening out the total downloaded data amount in the time period smaller than a first threshold value and the total downloaded data amount in the time period larger than a second threshold value in the downloaded data speed statistical table to obtain an updated downloaded data speed statistical table, wherein the first threshold value is smaller than the second threshold value.
In step a02, because the data will have unavoidable network fluctuation during network transmission, some values of the downloaded data amount that are significantly smaller or larger than the normal transmission rate range will occur, and therefore, in order to avoid the influence of these abnormal values on the accuracy of network downloading speed acquisition, the network downloading speed acquisition device sifts out the total downloaded data amount in the time period smaller than the first threshold and the total downloaded data amount in the time period larger than the second threshold in the downloaded data speed statistical table, and obtains an updated downloaded data speed statistical table, where the first threshold is smaller than the second threshold. It is understood that the first threshold and the second threshold are both positive integers, and both the first threshold and the second threshold may be preset according to the actual transmission rate of the target network, so as to screen out the total amount of downloaded data that obviously belongs to too small values or too large values in the network fluctuation.
Correspondingly, the specific execution process of step 400 is step 401: and calculating the average value of the total downloaded data in all time periods in the updated downloaded data speed statistical table, and determining the average value as the standard downloading speed of the target network.
As can be seen from the above description, the method for acquiring network download speed provided in the embodiment of the present invention can effectively solve the problem of inaccurate speed measurement result caused by network fluctuation by screening out the total amount of downloaded data in the time period smaller than the first threshold and the total amount of downloaded data in the time period larger than the second threshold in the downloaded data speed statistical table.
A third embodiment of the present invention provides a third specific implementation manner of the method for acquiring a network download speed, and referring to fig. 3, the method for acquiring a network download speed further includes the following steps:
between the above steps 300 and 400, the following steps a01, a03 to a05 are performed;
step A01: and generating a download data speed statistical table according to the total download data amount of the double threads in each time period, wherein the download data speed statistical table comprises a one-to-one mapping relation between each time period and the total download data amount of the double threads in each time period.
Step A03: and sorting the total downloaded data in each time period in the downloaded data speed statistical table according to the data quantity from less to more to obtain a data quantity sorting table.
Step A04: and deleting the data quantity which is equal to the first proportional value in the data quantity sorting table in the sequence from small to large, and deleting the data quantity which is equal to the second proportional value in the data quantity sorting table in the sequence from large to small to obtain the updated data quantity sorting table.
Step A05: and arranging the updated data quantity sorting table according to the sequence of each time period to obtain an updated download data speed statistical table.
Correspondingly, the specific execution process of step 400 is step 401: and calculating the average value of the total downloaded data in all time periods in the updated downloaded data speed statistical table, and determining the average value as the standard downloading speed of the target network.
As can be seen from the foregoing description, in the method for acquiring a network download speed according to the embodiment of the present invention, the data amount equal to the first ratio in the data amount sorting table is deleted in the order from small to large, and the data amount equal to the second ratio in the data amount sorting table is deleted in the order from large to small, so that the problem of inaccurate speed measurement result caused by network fluctuation can be further solved.
In a specific embodiment, the step 100 in the method for acquiring a network download speed specifically includes the following steps:
(1) and in the target network, controlling the first terminal to establish double-thread connection with the second terminal, wherein the second terminal stores two data files.
(2) Two data files are downloaded simultaneously and respectively in a target network by double threads, and timing is started respectively and simultaneously when each thread starts downloading.
Correspondingly, the step 200 in the method for acquiring the network download speed specifically includes the following steps:
(1) and periodically recording the download data amount of each thread in each time period at the same time interval during the downloading of the data files of each thread until the two data files are respectively downloaded, wherein the duration of each time period is equal to the time interval.
(2) And stopping the timing of each thread when the respective thread finishes downloading the data.
Correspondingly, the step 300 in the method for acquiring the network download speed specifically includes the following steps:
and summing the download data volume of each thread in each time period according to the timing result corresponding to the double threads to obtain the total download data volume of the double threads in each time period.
As can be seen from the above description, in the method for acquiring a network download speed in the embodiment of the present invention, the accuracy of subsequently acquiring the total amount of downloaded data in each time period can be ensured by starting timing when each thread starts to download data and finishing timing after finishing downloading data respectively.
To further explain the present solution, the present invention further provides an application example of a method for acquiring a network download speed, which is shown in fig. 4 and specifically includes the following contents:
the application example comprises a client terminal 10 as a first terminal and a server terminal 11 as a second terminal, and the working principle of the method is as follows:
step 201: and when the connection between the client and the server for testing is finished, recording the current time stamp t1 before starting the network downloading speed test.
Step 202: the timestamp t1 begins, and the client uses the double threads th1 and th2 to simultaneously and remotely download two files at the server endf2, the used protocol is downloading through the URL of HTTP, and putting in the container c1 created by ExecutionService starts downloading synchronously.
Step 203: the timer1 and the timer2 are used for recording the accumulated download data amount of the threads th1 and th2 respectively, and the accumulated download data amount of different time periods is recorded in the form of arraylist lists a1 and a 2.
Step 204: the accumulated download data added by the lists a1 and a2 calculates the total download data amount a 3;
step 205: the a3 gets the fastest 10% and the slowest 25% by deleting, and optimizes to get a new result list a4, and then takes the average value as the final result.
From the above description, it can be known that the method for acquiring the network download speed in the application example of the present invention can solve the influence caused by the network fluctuation and the fluctuation of file download transmission, and improve the accuracy of the network speed measurement result.
