Detailed Description
The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
The present disclosure may be embodied or carried out in other specific forms, such as for example only , without departing from the spirit of the disclosure.
Based on the present disclosure, it should be apparent to those skilled in the art that aspects described herein may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present disclosure, and the drawings only show the components related to the present disclosure rather than the number, shape and size of the components in actual implementation, the type, quantity and ratio of the components in actual implementation can be random changes, and the layout of the components may be more complicated.
In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.
The file download speed limiting method provided by the embodiment can be executed by computing device which can be implemented as software or as a combination of software and hardware, and the computing device can be integrally arranged in a server, a client device and the like.
In addition, in the embodiment of the present disclosure, a video file and an audio file (hereinafter, simply referred to as a video-audio file) are described as examples of files that need to be downloaded, but it should be understood that the files are not limited to the video-audio file, but may include other types of files.
The interface flow limitation is to limit the flow of the interface, including concurrent flow and total flow within time, so as to prevent the system pressure from being too large, ensure that resources requested by the user are kept uniform and shield malicious requests, therefore, all requests in the actual application scene are treated equally, as long as the interface flow does not exceed the upper limit, the requests of the user are not limited, and flow is excessive, all subsequent requests can be directly rejected.
Referring to fig. 1, an embodiment of the present disclosure provides file download speed limiting methods, where the file download speed limiting method includes:
s100: and acquiring the code rate of the file.
When downloading video and audio files on the network by using a Streaming transport technology (HTTP Live Streaming, HLS), an HLS client first sends a request for video and audio to a video and audio server, receives a configuration file in m3u8 format sent by the video and audio server, and then selects a corresponding file to download, so that the client can play the video and audio.
The server obtains times of code rate of video and audio corresponding to each received video and audio request, the video and audio request generally includes video and audio identifiers of the requested video and audio, such as video and audio names, video and audio addresses, and according to the video and audio identifiers, related information of the video and audio, such as code rate, format, size, and the like, can be obtained.
For a video/audio file with a constant code rate, the code rate can be calculated according to the following formula:
rate (video file size × 8)/time, where the unit of rate is kbps, the unit of video file size is KB, and the unit of time is s.
Specifically, for a ts, mp4 and other format video file, a corresponding metadata file exists, and the file contains information of url, header, file size and the like.
It should be understood that the bitrate of retrieving the file is not limited to the above implementations, and any existing and future-developed implementations are possible as long as they can retrieve the bitrate of the file.
In addition, it should also be understood that, in the case where the file download rate limiting method is performed in the server, the bitrate of the obtained file does not need to be transmitted to the client.
S200: and setting speed limit information of the file, wherein the speed limit information indicates a speed limit value when speed limit operation is performed on the file, and the speed limit value is related to the code rate of the file.
During the downloading process of the file, the downloading speed may need to be limited due to the limitations of the memory size of the client, the network resources and the bearing capacity of the system.
In the embodiment of the disclosure, the speed limit information based on the code rate of the video and audio file is set. Specifically, the speed limit information is set for each video-audio file, and the set speed limit information indicates a speed limit value when the speed limit operation is performed at the time of downloading the file.
In the present exemplary embodiment, the speed limit value corresponds to a code rate of the file, and specifically, for example, 20% of the code rate may be used as the speed limit value.
For example, if the video rate of the video to be downloaded is 5MB/S in the video and audio request received by the server, the output rate for downloading the video and audio can be set to be 4MB/S (20% of the speed limit) in the case of executing the speed limit.
In the embodiment of the disclosure, for each video request, the output flow of the server is limited according to the code rate of the video, so that it is ensured that the maximum download rate that can be achieved when different videos are downloaded does not exceed the upper limit of the output rate set according to the code rate, and thus the basically same speed limit degree can be implemented for files with different code rates, and the problem that the video and audio files with higher code rates are severely jammed under the condition of speed limit according to an empirical value or the unified standard is not caused.
S300: and determining whether to execute the speed limit operation on the file according to the peak time and/or bandwidth resource of the network.
For the network for downloading the video and audio files, the number of clients accessed during the peak period from 8 o 'clock to 10 o' clock is increased, the network load is increased, and the resources capable of being provided for downloading the video and audio files are limited.
In another aspect , when a large amount of bandwidth resources consuming clients are accessed in a network, the output rate of a server providing video and audio files may be lower than the bitrate without changing the bandwidth resources.
Therefore, there is a need for speed-limiting operations during peak hours and/or in the event of insufficient bandwidth resources.
S400: and when the speed limit operation is determined to be executed, executing the speed limit operation on the file according to the speed limit information of the file.
When it is determined that the speed limit needs to be executed according to the determination condition of step S300, the speed limit operation is executed for downloading the video and audio file.
For example, in the case where the bit rate of the video/audio file is 5MB/S, in the case where the speed limit operation is performed, the output rate of the corresponding server is limited to 4 MB/S.
According to the file downloading speed-limiting scheme disclosed by the invention, not only can bandwidth resources be saved, but also the blockage can not be caused, and the cost can be reduced according to the charging characteristics.
According to specific implementation manners of the embodiment of the present disclosure, the audio file and the video file are variable bitrate coding files, and speed limit information is set for portions of the variable bitrate coding files with different bitrate.
In the HTTP adaptive video streaming technology, video sources can be encoded into multiple videos with different video bit rates by an encoder and stored on a server, and meanwhile, each bit rate video is divided into different segments (parts), each segment represents fixed-time video playing.
In other words, the speed limit information can be set for each part, thus the output flow of the server can be dynamically adjusted according to the part to be downloaded when downloading is carried out, thereby realizing the speed limit caused by for the variable code rate coding file.
According to specific implementation manners of the embodiment of the present disclosure, the maximum speed of downloading the video and audio file is further set according to the code rate of the video and audio file.
For example, the upper limit of the output rate of the server (the downloading speed of the video and audio files) can be set to be N times of the code rate, wherein N is greater than or equal to 1.
The size of N may be set according to an upper limit of the total output traffic that can be provided by the server. If the total output traffic upper bound of the server is insufficient, N may be set to 1; if the total output traffic upper limit of the server is large, the value of N may also be increased accordingly.
And aiming at each video request, limiting the output flow of the server according to the code rate of the video, so that the maximum download rate which can be reached when different videos are downloaded can not exceed the upper limit of the output rate set according to the code rate. Therefore, each user requesting the video is guaranteed to obtain smooth video playing experience, and the video file with the smaller code rate is not allocated with too high bandwidth flow, so that the bandwidth flow of the server is greatly saved, and the utilization rate of the network is improved.
Referring to fig. 2, according to specific implementation manners of the embodiment of the present disclosure, the setting of the speed limit information of the file includes:
s201: and setting speed limit information according to the code rate of the file.
And S202, generating a speed limit value in a resource locator or a custom header of the system of the file according to the speed limit information.
For the set speed limit information, the speed limit information can be written into the system resource locator or the custom header of the video and audio file, so that the server can execute speed limit operation under the condition that the condition is met according to the speed limit information written into the system resource locator or the custom header of the file.
The role of the custom header (header) is to send header information to the client. The specific content can be set by self according to the environment. For example, the custom header may contain server information, date, length of audio-visual content, and the like. The speed limit value generates speed limit information of a threshold value, speed limit information of a speed limit factor and other speed limit information in a custom header of the file. The header is described in detail, for example, inhttps://www.cnblogs.com/fengzheng126/archive/2012/04/ 21/2461475.htmlThe entire contents of which are hereby incorporated by reference.
Referring to fig. 3, according to specific implementation manners of the embodiment of the present disclosure, for determining whether to perform a speed limit operation on the file according to a peak time of a network, the method includes:
s301: the peak time of the network is determined.
In the disclosed embodiments, the peak time of the network may be determined in a directly defined manner. For example, a value of [ 0: 00,8: 00] as off-peak hours, and [ 20: 00, 24: 00) as the peak time.
Alternatively, the network peak model may be derived by simulation of historical network peak times. As described in chinese invention patent application No. CN201810793285.7, it can be assumed that the arrival of a user's request for video and audio follows a poisson distribution and the duration follows an exponential distribution, with an average of 1 hour, and the [ 0: 00,8: 00] (rest time), [ 8: 00, 20: 00] (office hours) and [ 20: 00, 24: 00) (subsequent times) as typical off-peak, mid-peak and peak times, respectively.
S302: and determining whether the current downloading time reaches a preset downloading speed-limiting time point or time interval, and executing the speed-limiting operation if the current downloading time reaches the preset downloading speed-limiting time point or time interval.
After the network peak time is determined, the speed limit operation can be performed as long as the peak time point is reached. In the case where the network peak is determined by simulation, the peak time obtained by simulation based on the history data may be changed, and in this case, the speed limit operation may be performed at the peak time obtained by simulation.
Referring to fig. 4, according to specific implementation manners of the embodiment of the present disclosure, it may also be determined whether to perform the speed-limiting operation on the file according to the bandwidth resource of the network.
S401, receiving a downloading request sent by a client.
The download network of the disclosed embodiments consists of a server and at least clients connected to the server, when any client needs to download a file, a download request will be sent to the server.
S402, distributing idle tokens for the downloading request and checking the current available bandwidth.
The server is provided with a download pool and a preset number of tokens, the download pool comprises download threads corresponding to the number of the tokens in the server, and the download threads can be started through the tokens to download the files required by the client into the download pool.
The server will check if there are free tokens after receiving the download request, if so, the server will allocate free tokens to the download request, meanwhile, the server will detect the usage status of the bandwidth in the download pool, including the current available bandwidth and the preset total download bandwidth.
S403: and if the ratio of the available bandwidth to the total download bandwidth (bandwidth resource availability) is less than a preset ratio threshold, setting the download speed of the token as the speed-limiting bandwidth or executing speed-limiting operation on the file.
The server compares the available bandwidth with the total download bandwidth, if the ratio of the available bandwidth to the total download bandwidth is smaller than a preset ratio threshold, for example, 20%, the server determines that the available bandwidth is insufficient, and sets the download speed of the token to a rate-limiting bandwidth (for example, N times of a code rate) or performs a rate-limiting operation, and if the ratio of the available bandwidth to the total download bandwidth is not smaller than the preset ratio threshold, the download speed of the token is not limited.
According to specific implementation manners of the embodiment of the disclosure, for the determined peak time and the bandwidth resource utilization rate of the network, a grade can be further set, and the degree of the speed-limiting operation can be determined according to the set grade.
For example, for off-peak hours, mid-peak hours, and peak hours, 10% of the rate-limited code rate and 20% of the rate-limited code rate may be performed, respectively. For the bandwidth resource utilization rate of the network, when the ratio is greater than 30%, the speed is not limited, when the ratio is 10% -30%, the speed limit code rate is 10%, and when the ratio is less than 10% of the speed limit code rate, the speed limit code rate is 20%.
That is, the peak times may be classified, and when the current download time reaches the peak time, a speed limit operation corresponding to the classification of the peak time is performed, and speed limit operations of different degrees are performed on the peak times of different classifications.
Further, the bandwidth resource availability may be ranked; and executing speed-limiting operations corresponding to the grades of the bandwidth resource availability, wherein the speed-limiting operations of different degrees are executed on the bandwidth resource availability of different grades.
