Description
Technical Field
The present invention relates to the field of internet technologies, and in particular, to a file pushing method and apparatus, an electronic device, and a medium.
Background
Since the files that the user has read and the files that the server pushes are stored in the user device in a large amount, the files can not only be read by the user device, but also be accessed or downloaded by other user devices. Therefore, for some files which are expected to have a large access demand, the files can be stored in a large amount in the user equipment (for example, a Personal Computer (PC), a smart television) in advance by means of pushing, so that other user equipment can read the files from the user equipment nearby when the other user equipment needs to read the files.
However, the time that the user device is online is not controllable, and when the user device is not online, other user devices cannot read files from the user device. Therefore, when the server pushes the file to the user equipment, the server can push the file to the plurality of user equipment according to a certain pushing redundancy rate. When other user equipment needs to acquire the file, even if some user equipment which pushes the file is not online, the user equipment can acquire the file from the online user equipment which pushes the file.
However, in the prior art, the push redundancy rate of each file is fixed, but there is a difference in the acquisition requirements of users for each file, and for a file with a smaller acquisition requirement, if the file is pushed with a larger redundancy rate, a large number of terminals store the file, so that the storage amount of the file in the terminal far exceeds the acquisition requirement of the file, and a large amount of storage resources are wasted.

Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Referring to fig. 1, a file pushing system provided in an embodiment of the present invention includes: a server and a terminal.
The server is used for pushing files to the terminal, and the terminal is used for downloading the files pushed by the server. The number of the terminals and the servers in the embodiment of the present invention may be one or more, fig. 1 is an example provided by the present invention, and the embodiment of the present invention does not specifically limit the number of the devices included in the file push system.
Referring to fig. 2, an embodiment of the present invention provides a file pushing method, which is applied to a server in the file pushing system shown in fig. 1, and includes the following steps:
Optionally, the file source may include two types, where one type of file source includes file information of a file to be pushed. Wherein the file information includes: attribute information and address information of the file to be pushed. When the server detects that the file source comprises the file information, the attribute information in the file information is obtained.
Another type of file source may include file information of each file, where the file information of each file includes: attribute information of the file, address information, current playing amount of the file, the number of terminals which are currently in an online state and store the file, and the like. The server can screen out the files to be pushed from the files and then acquire the attribute information of the files to be pushed. For example, for each file in the file source, it is determined whether a ratio of a current playing amount of the file to the number of terminals currently in an online state and storing the file is greater than a preset ratio, and the file having the ratio of the current playing amount to the number of terminals currently in the online state and storing the file greater than the preset ratio is determined as the file to be pushed, and attribute information of the file to be pushed is obtained.
In the embodiment of the invention, the file to be pushed can be a multimedia resource file such as a video file, an audio file or a picture file.
Optionally, taking a file to be pushed as a video file as an example, the attribute information of the file to be pushed includes: bit rate, file type, video type, number of release days, etc.
For example, the file type may be Motion Picture Experts Group (MPEG), Audio Video Interleaved (AVI).
The video types may be: movies, television shows, art or animation, etc. The type of the video can be further divided, for example, the movie is divided into: suspense, act, war or history, etc. The embodiment of the present invention is not particularly limited thereto.
The number of release days is the number of days from the release date of the file to the current date. For example: and if the number of days for releasing the files to be pushed is 0, acquiring the files with the same attribute information as the files to be pushed from the files pushed on the same day.
It can be understood that the program source stores the pushing time periods of the files, and the target file can be screened from the files in the preset time period in the pushing time period, and the attribute information of the target file can be acquired from the file source. Or, the file information including the access amount and the push redundancy rate may be used as a file to be pushed to the terminal within a preset time period, a target file is screened out from the file information, and attribute information of the target file is acquired from a file source.
In one embodiment, the attribute information includes a plurality of attributes, and for each file to be pushed to the terminal within a preset time period, each attribute included in the attribute information of the file may be compared with a corresponding attribute in the attribute information of the file to be pushed. And then determining the file with the same attribute as the corresponding attribute in the attribute information of the file to be pushed, wherein the attribute information comprises the attribute information, as a target file.
For example: taking the file to be pushed as a video as an example, the attribute information includes: bitrate, file type, and video type. Suppose the attribute information of the file to be pushed is: 600 Bit rate (Bit Per Second, bps), MPEG, movie. The files pushed to the terminal within the preset time period comprise: file 1, file 2, and file 3. Wherein, the attribute information of the file 1 is: 500bps, MPEG, TV play. The attribute information of the file 2 is: 500bps, AVI, movie. The attribute information of the file 3 is: 600bps, MPEG, movies. So the target file is file 3.
It is understood that the push redundancy rate corresponding to the target file may represent a ratio of the total number of pushed copies of the target file to an expected required amount of the target file, and the access amount of the target file may include the number of reads of the target file in a specified time period.
And 204, adjusting the push redundancy rate corresponding to the target file according to the access amount, and taking the adjusted push redundancy rate as the push redundancy rate corresponding to the file to be pushed.
The pushing redundancy rate corresponding to the file to be pushed is used for expressing the ratio of the total number of copies to be pushed of the file to be pushed to the required amount of the file to be pushed.
Alternatively, the demanded quantity of the file to be pushed may be a demanded quantity expected by the file to be pushed, and may be set in advance. After the push redundancy rate of the file to be pushed is determined, the product of the push redundancy rate and the expected demanded quantity of the file to be pushed can be calculated to obtain the total number of pushed copies of the file to be pushed.
For example, the demanded quantity may be an expected playing time, and the push redundancy rate of the file to be pushed may be: the total number of copies to be pushed/the expected number of plays of the file to be pushed. And the predicted playing times are the playing times of the file to be pushed after being predicted to be pushed.
And step 205, pushing the file to be pushed to the terminal according to the pushing redundancy rate corresponding to the file to be pushed.
In an embodiment, the server may calculate the total number of to-be-pushed copies corresponding to the to-be-pushed file according to the pushing redundancy rate corresponding to the to-be-pushed file. After receiving a download request sent by a terminal in an idle state, if the current number of delivered copies of a file to be pushed does not reach the total number of delivered copies, the server may send address information of the file to be pushed to the terminal, so that the terminal obtains the file to be pushed from a storage device (e.g., a Content Delivery Network (CDN) server) corresponding to the address information. And if the current distribution number of the files to be pushed reaches the total number of the files to be pushed, not pushing the files to be pushed to the terminal.
The embodiment of the invention at least comprises the following beneficial effects: according to the embodiment of the invention, when the push redundancy rate corresponding to the target file does not meet the preset condition, the push redundancy rate corresponding to the target file can be adjusted, and the adjusted push redundancy rate is used as the push redundancy rate of the file to be pushed, so that the push redundancy rate in the embodiment of the invention is not fixed and can be flexibly adjusted. For a file to be pushed with a smaller acquisition demand, a target file with the same smaller historical acquisition demand is found, if the push redundancy rate corresponding to the target file does not meet the preset condition, the push redundancy rate corresponding to the target file is indicated to be larger, the push redundancy rate corresponding to the target file can be reduced, and the reduced push redundancy rate is used as the predicted push redundancy rate of the file to be pushed. Because the push redundancy rate corresponding to the file to be pushed is used for representing the ratio of the total number of copies to be pushed of the file to be pushed to the required amount of the file to be pushed, the reduced redundancy rate is utilized for pushing, so that the difference between the total number of copies to be pushed of the file to be pushed and the required amount of the file to be pushed can be reduced, and the waste of storage resources caused by pushing the file to be pushed is reduced.
Optionally, referring to fig. 3, the manner for determining whether the push redundancy rate corresponding to the target file meets the preset condition in step 203 includes the following steps:
Optionally, the access amount of the target file in step 203 may be obtained from a file source, where the access amount of the target file includes: the number of reads of the target file and the number of remaining copies in a specified period of time.
Wherein, the reading times refer to the times of reading the target file in a specified time period. For example: the playing amount of a video within 3 to 4 hours after the video is pushed. It can be understood that the number of times of reading the target file is the sum of the number of times of reading the target file by each device. Which comprises the following steps: the number of times that the device which is pushed the target file reads the target file, the number of times that the device which is not pushed the target file reads the target file from the device which is pushed the target file, and the number of times that the device which is not pushed the target file reads the target file from the server.
The remaining number of pushed copies refers to the number of terminals in an online state in terminals which have pushed the target file within a specified time period. For example: and within 3-4 hours of the pushing time of one video, the number of terminals in an online state in the terminals for pushing the video is counted. It can be understood that the online number of the terminal in the specified time period is constantly changing, so the average value of the online number in the specified time period can be taken as the number of the terminals in the online state in the specified time period. Or, other methods may also be adopted to determine the number of terminals in the online state in a specified time period, which is not specifically limited in the present invention.
Optionally, if the target file is a plurality of files, the redundancy ratio values of the plurality of files may be calculated respectively, an average value of the plurality of ratio values is calculated, and it is determined whether the average value is greater than a first preset threshold and smaller than a second preset threshold.
Step 302, determining that the push redundancy rate corresponding to the target file meets a preset condition.
It can be understood that the redundancy ratio is greater than the first preset threshold and less than the second preset threshold, the difference between the remaining pushed copies and the reading times meets the preset difference, and at this time, the remaining pushed copies can meet the reading requirement of the file to be pushed, and excessive storage resources in the terminal are not wasted.
For example, a first preset threshold value of 20 and a second preset threshold value of 40 may be set.
Optionally, if the push redundancy rate corresponding to the target file meets the preset condition, the push redundancy rate corresponding to the target file may be used as the push redundancy rate corresponding to the file to be pushed.
The method and the device have the advantages that the pushing redundancy rate corresponding to the target file meets the preset condition, the fact that the target file is pushed by the aid of the pushing redundancy rate corresponding to the target file is appropriate, the attribute information of the file to be pushed is the same as that of the target file, and the file to be pushed and the target file are similar files, the pushing redundancy rate corresponding to the target file is used as the pushing redundancy rate corresponding to the file to be pushed, so that the pushing redundancy rate corresponding to the file to be pushed obtained by the embodiment of the invention is more accurate, and the total pushing number of the file to be pushed predicted according to the pushing redundancy rate corresponding to the file to be pushed is more accurate.
It can be understood that the redundancy ratio is not less than the second preset threshold, which indicates that the redundancy ratio of the remaining number of pushed copies of the target file to the number of reads is large. When the redundancy ratio of the residual pushing number of the target file to the reading times is large, the number of terminals in an online state in the terminals of the pushed target file in the specified time period is large, the reading times of the target file is small, namely the required quantity of the target file is small, and the pushing redundancy ratio is adopted to push the target file, so that the storage resource of the terminal is wasted. The push redundancy rate of the target file does not satisfy the preset condition.
The redundancy rate ratio is not greater than a first preset threshold, which indicates that the redundancy rate ratio of the residual pushed copies of the target file to the reading times is smaller. When the redundancy ratio of the remaining pushed copy number of the target file to the reading times is small, the number of terminals in an online state in the terminals pushed with the target file in a specified time period is small, the reading times of the target file are large, namely the required amount of the target file is large, and at this time, the remaining pushed copy number cannot meet the acquisition requirement of a user on the target file. Therefore, the push redundancy rate corresponding to the target file does not meet the preset condition, and therefore, the push redundancy rate of the target file is not suitable to be used as the push redundancy rate of the file to be pushed.
The embodiment of the invention also has the following beneficial effects: the embodiment of the invention can determine whether the push redundancy rate corresponding to the target file meets the preset condition by judging whether the redundancy rate ratio of the residual copy number of the target file to the reading times is greater than a first preset threshold and less than a second preset threshold. The rationality of the push redundancy rates corresponding to the target files is quantized, the reasonable degree of the push redundancy rates corresponding to the files can be accurately distinguished, and the efficiency and the accuracy of determining the push redundancy rates corresponding to the files to be pushed are improved.
Optionally, the manner of adjusting the push redundancy rate corresponding to the target file in step 204 includes the following two cases:
in the first case, if the redundancy rate ratio is not greater than the first preset threshold, the push redundancy rate corresponding to the target file is increased according to the difference between the first preset threshold and the redundancy rate ratio.
It can be understood that, when the redundancy ratio of the remaining number of pushed copies of the target file to the number of reading times is not greater than the first preset threshold, the number of reading times of the target file in the specified time period is large, the number of terminals which have been pushed and are in the online state is small, and the number of terminals which have been pushed and are in the online state may not meet the reading requirement of the target file. If the push redundancy rate corresponding to the target file is directly determined as the push redundancy rate corresponding to the file to be pushed, because the file to be pushed is similar to the target file, after the file to be pushed is pushed by using the push redundancy rate corresponding to the target file, the situation that the number of terminals which are already pushed to the file to be pushed and are in an online state cannot meet the reading requirement of the file to be pushed may also occur. Therefore, the push redundancy rate corresponding to the target file can be increased, and the increased push redundancy rate is used as the push redundancy rate corresponding to the file to be pushed.
Optionally, the push redundancy rate corresponding to the target file may be increased by a difference between a first preset threshold and a redundancy rate ratio, and the increased push redundancy rate is used as the push redundancy rate corresponding to the file to be pushed. Alternatively, the specified amount may be increased based on the difference between the first preset threshold and the redundancy rate ratio, for example, 2 times the difference between the first preset threshold and the redundancy rate ratio. The present invention is not particularly limited to the specified number of increments.
And in the second situation, if the redundancy rate ratio is not less than the second preset threshold, reducing the push redundancy rate corresponding to the target file according to the difference between the redundancy rate ratio and the second preset threshold.
It can be understood that, when the redundancy ratio of the remaining number of pushed copies of the target file to the number of read times is not less than the second preset threshold, the number of read times of the target file in the specified time period is small, the number of terminals that have been pushed and are in an online state is large, and the number of terminals that have been pushed and are in an online state exceeds the read requirement of the target file, which may result in waste of storage resources in the terminals. If the push redundancy rate corresponding to the target file is directly determined as the push redundancy rate corresponding to the file to be pushed, and the file to be pushed is similar to the target file, after the file to be pushed is pushed by using the push redundancy rate corresponding to the target file, the situation that the number of terminals which are already pushed to the file to be pushed and are in an online state exceeds the reading requirement of the file to be pushed can also occur. Therefore, the push redundancy rate corresponding to the target file can be reduced, and the reduced push redundancy rate is used as the push redundancy rate corresponding to the file to be pushed.
Optionally, the push redundancy rate corresponding to the target file may be reduced by a difference between the redundancy rate ratio and a second preset threshold, and the reduced push redundancy rate is used as the push redundancy rate corresponding to the file to be pushed. Alternatively, the specified amount may be reduced based on the difference between the redundancy rate ratio and the second preset threshold, for example, 2 times the difference between the redundancy rate ratio and the second preset threshold. The present invention is not particularly limited to the specified number of reductions.
Optionally, referring to fig. 4, the manner for pushing the file to be pushed to the terminal in step 205 includes the following steps.
Step 401, calculating the total number of to-be-pushed copies of the to-be-pushed file according to the pushing redundancy rate corresponding to the to-be-pushed file.
In one embodiment, a product of a push redundancy rate corresponding to a file to be pushed and a required amount of the file to be pushed may be calculated, and a calculation result may be determined as a total number of copies to be pushed of the file to be pushed.
The required amount of the file to be pushed may be determined based on the number of times of reading the target file, or may also be determined in other manners, which is not specifically limited in the embodiment of the present invention.
Step 402, for each area to be pushed, calculating the number of the parts to be pushed corresponding to the area to be pushed according to the online probability of the terminal in the area to be pushed and the total number of the parts to be pushed of the files to be pushed.
In one embodiment, for each to-be-pushed area, a ratio of the number of devices in the to-be-pushed area to the total number of devices in each to-be-pushed area is calculated, then the ratio is multiplied by the total number of pushed copies of the to-be-pushed file, and then the number of to-be-pushed copies corresponding to the to-be-pushed area is determined according to the calculation result and the online probability of the terminal in the to-be-pushed area.
Optionally, the server may predict the online probability of each terminal in each time period of a day according to the online condition of each terminal in the area to be pushed in each time period of a day in the specified time range.
Optionally, the manner in which the server determines whether the terminal is online may include the following two manners. One is that the server sends a specified message to the terminal at specified time intervals, and if the message replied by the terminal for the specified message is not received within the overtime, the terminal is determined not to be on-line; and if the message replied by the terminal aiming at the specified message is received within the overtime length, determining that the terminal is online.
The other is that the terminal sends a specified message to the server at specified time intervals, and if the server does not receive the specified message sent by the terminal within the specified time, the terminal is determined not to be on-line; and if the server receives the appointed message sent by the terminal within the appointed time length, determining that the terminal is online.
The terminal in the embodiment of the invention can comprise equipment which is in an online state, has an idle load and has a storage space larger than a preset storage space. For example: the terminal may be a Personal Computer (PC) or a television set that is on-line and currently has no download task.
For example: the total number of pushed files is 15000, the area a to be pushed comprises 100 ten thousand PCs, and each area a to be pushed comprises 1000 ten thousand PCs in total, and then the number of distributed files in the area a to be pushed is determined to be (100 ten thousand/1000 ten thousand) × 15000-1500.
Assuming that the number of the terminals currently in an online state in the area a to be pushed is 20 thousands, classifying the 20 thousands of terminals according to a preset classification rule, wherein the terminals with high late peak online probability include 15 thousands, and the terminals with low late peak online probability include 5 thousands.
1500 parts of files to be pushed corresponding to the area A to be pushed can be divided into two groups, and each group comprises 750 parts. And multiplying 750 parts of the group by a specified coefficient, wherein if the specified coefficient is 1.2, the 750 multiplied by 1.2 is 900 parts, and the number of parts to be pushed corresponding to the area A to be pushed is 750 plus 900 parts to 1650 parts.
It can be understood that the file to be pushed may be pushed to a terminal with a low late peak online probability, and in order to enable the number of terminals that have pushed the file to be pushed and are in an online state in the late peak period to meet the demanded quantity of the file to be pushed, a certain number may be added on the basis of the allocated number of copies of the area to be pushed, and the number is used as the number of copies to be pushed corresponding to the area to be pushed.
And step 403, pushing the files to be pushed to the specified number of terminals in the area to be pushed.
The specified number is equal to the number of the to-be-pushed copies corresponding to the to-be-pushed area.
For example, assuming that the file to be pushed is file 1, and the number of copies to be pushed of file 1 corresponding to one area to be pushed is 1500, file 1 may be pushed to 1500 terminals that send download requests to the server according to the sequence of sending download requests to the server by each terminal in the area to be pushed, and file 1 is no longer pushed to terminals that subsequently send download requests to the server in the area to be pushed.
For another example, when the files to be pushed are file 1 and file 2. The number of the to-be-pushed copies of the file 1 corresponding to one to-be-pushed area is 1000, and the number of the to-be-pushed copies of the file 2 is 2000. According to the sequence of sending the download request to the server by each terminal in the area to be pushed, the file 1 and the file 2 can be pushed to the front 1000 terminals sending the download request to the server, and the file 2 can be pushed to the back 1000 terminals sending the download request to the server.
The embodiment of the invention also has the following beneficial effects: due to the fact that access requirements of the areas for the files to be pushed are different, the files to be pushed need different pushing numbers in each area, and the pushing number of the files to be pushed in each area can be determined, so that the application range of the embodiment of the invention is wider.
In order to more clearly illustrate the embodiment of the present invention, referring to fig. 5, a file pushing method provided by the embodiment of the present invention may include the following steps:
and 505, determining the number of copies to be pushed corresponding to each area to be pushed according to the pushing redundancy rate corresponding to the file to be pushed and the collected online probability of the terminal in each area to be pushed.
The embodiment of the invention also has the following beneficial effects: according to the embodiment of the invention, the target file with the same attribute information as the file to be pushed can be obtained from the file which is pushed historically (the file which is pushed to the terminal within the preset time period), and the pushing redundancy rate of the file to be pushed is predicted according to the access amount and the pushing redundancy rate of the target file, so that the predicted pushing redundancy rate is more accurate, and the method and the device are more suitable for determining the total number of the file to be pushed.
