Description

Technical Field

[0001] The present invention relates to the technical field of file transmission, and in particular to a scene-adaptive file transmission method, device, equipment and storage medium. Background Art

[0002] Massive file transfer refers to the transfer of large amounts of files at the TB level or even TB level. Massive files have always been criticized for their large data volume (usually up to TB / PB level) and long transfer time.

[0003] At present, the relevant technologies for mass file transmission usually transmit through packaging, parallelization and other methods, and the effects vary greatly in different environments. Because they do not take into account the specific situation of the files to be transmitted and the transmission conditions, lack consideration of scenarios such as multiple complex file types and external network status factors, the effects in actual production environments are often unsatisfactory.

[0004] For massive small files in massive file transfer, the bottleneck is low CPU or bandwidth utilization and long transmission time. The current common optimization solution is to achieve faster transmission through concurrency. When a file transfer is completed, an acknowledgement character (ack) is responded. When the number of files is large, many ack responses are required, resulting in long transmission time and low transmission efficiency. Summary of the invention

[0005] In view of this, the present invention provides a scenario-adaptive file transmission method, device, equipment and storage medium to solve the technical problem of low efficiency in existing mass file transmission.

[0006] In a first aspect, the present invention provides a file transfer method for an adaptive scenario, comprising: obtaining file attributes of a file to be transferred, the file attributes including a file size; screening out a first category of transfer files whose file size is less than a set value according to the file attributes; dividing a collection of the first category of transfer files into several batch transmissions, and performing a confirmation character response after a single batch transmission.

[0007] The present invention provides an adaptive scenario file transmission method, which obtains the file attributes of the files to be transmitted, screens out the first category of transmission files whose file sizes are smaller than a set value according to the file attributes, divides the collection of the first category of transmission files into several batch transmissions, and performs a confirmation character response after a single batch transmission. After successfully transmitting several first category transmission files with smaller file sizes in batches at one time, a confirmation character response is performed again. For a large number of small files, the process of confirming character responses can be reduced for many times, thereby greatly shortening the total time consumed for file transmission.

[0008] Optionally, before dividing the set of the first category transmission files into several batch transmissions and performing a confirmation character response after a single batch transmission, it also includes: obtaining the network status of the transmission device; and confirming the number of the first category transmission files in a single batch transmission based on the network status.

[0009] In this way, the number of files transferred in a single batch is dynamically adjusted according to the network status, which can better adapt to network fluctuations and improve the stability and efficiency of transmission.

[0010] Optionally, the network status includes network delay, and confirming the number of the first category transmission files for a single batch transmission based on the network status includes: if the network delay is greater than the set initial delay, reducing the number of the first category transmission files for a single batch transmission; if the network delay is less than the set initial delay, increasing the number of the first category transmission files for a single batch transmission.

[0011] By dynamically adjusting the transmission quantity to adapt to changes in network delay, transmission interruption or data loss caused by network delay can be reduced and transmission reliability can be improved.

[0012] Optionally, after obtaining the file attributes of the file to be transmitted, it also includes: filtering out second-category transmission files whose file size is greater than or equal to a set value according to the file attributes; judging whether the host resource status of the transmission device is sufficient; if the host resource status is sufficient, dividing the second-category transmission file into blocks according to the set block size to obtain a number of file blocks, and transmitting the several file blocks in parallel; if the host resource status is insufficient, directly transmitting the second-category transmission file.

[0013] By judging the host resource status and selecting block processing or direct transmission, the host resources can be used more effectively and the transmission efficiency of the second type of transmission files with larger file sizes can be improved.

[0014] Optionally, before the second-type transmission file is divided into blocks according to the set block size to obtain a plurality of file blocks, the method includes: obtaining a network status of a transmission device; and determining a block size according to the network status.

[0015] Determining the block size according to the network status can better adapt to changes in network bandwidth and optimize transmission efficiency.

[0016] Optionally, the network status includes network bandwidth, and determining the block size based on the network status includes: judging whether the network bandwidth is less than a first bandwidth setting value; if the network bandwidth is less than the first bandwidth setting value, setting the block size to a first preset size; if the network bandwidth is greater than the first bandwidth setting value, setting the block size to increase proportionally with the network bandwidth, and the block size is not greater than a second preset size.

[0017] By setting different block sizes to adapt to different network bandwidths, you can reduce the transmission bottleneck caused by network bandwidth limitations and increase the transmission speed of large files.

[0018] Optionally, the file attributes also include a file type. Before transmitting several of the file blocks in parallel or directly transmitting the second-type transmission file, the following steps are performed: confirming whether the second-type transmission file is a default uncompressed file based on the file type; if the second-type transmission file is a default uncompressed file, compressing the file block or the second-type transmission file.

[0019] Since compression itself consumes resources, when the compressibility ratio of a file is very low, compressed transmission will be counterproductive and prolong the transmission time. Therefore, different transmission methods need to be adopted according to the file type to effectively shorten the transmission time. The default uncompressed file is a file with a relatively high compressibility ratio. Only the default uncompressed file can avoid unnecessary compression and improve the transmission time.

[0020] In a second aspect, the present invention provides a file transfer device for an adaptive scenario, comprising: an attribute acquisition module, used to obtain file attributes of a file to be transferred, the file attributes including the file size; a file type screening module, used to screen out a first category of transfer files whose file size is less than a set value according to the file attributes; a batch transfer module, used to divide the set of the first category of transfer files into several batch transfers, and perform a confirmation character response after a single batch transfer.

[0021] In a third aspect, the present invention provides a computer device, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the adaptive scenario file transfer method of the above-mentioned first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0022] In a fourth aspect, the present invention provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to enable a computer to execute the scene-adaptive file transfer method of the first aspect or any corresponding embodiment thereof.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] At present, the related technologies for mass file transmission usually transmit through packaging, parallelization and other methods, and the effects vary greatly in different environments. Because it does not take into account the specific situation of the files to be transmitted and the transmission conditions, lacks consideration of scenarios such as multiple complex file types and external network status factors, the effect in the actual production environment is often unsatisfactory. Based on this, an embodiment of the present invention provides a scene-adaptive file transmission method, which can automatically identify the transmission scene, adopt different transmission strategies for different scenes and network conditions, and effectively shorten the transmission time.

[0032] According to an embodiment of the present invention, an embodiment of a file transfer method for an adaptive scenario is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] In this embodiment, a scenario-adaptive file transmission method is provided, which can be used in mobile terminals, such as mobile phones, tablet computers, etc. Figure 1 As shown, the process includes the following steps:

[0034] Step S101, obtaining file attributes of a file to be transmitted, wherein the file attributes include the file size.

[0035] Specifically, when a large number of files need to be transferred, the file path of the file to be transferred is obtained, the entire directory structure indicated by the file path is scanned, and all files and their related attributes, such as file size, file type, etc., are obtained.

[0036] Step S102: Filter out the first type of transfer files whose file sizes are smaller than a set value according to the file attributes.

[0037] Specifically, the file size of each file to be transmitted is compared with a set value, and when the file size is smaller than the set value, it is classified as a small file, that is, a first-class transmission file. The set value can be set according to the transmission requirements, for example, 1KB, 5KB, 10KB, etc.

[0038] Step S103, dividing the set of first-category transmission files into several batch transmissions, and performing a confirmation character response after a single batch transmission.

[0039] like Figure 2 As shown, the number of files in each batch is set to k, and k can be set according to the specific scenario, for example, 500, 1000, etc. After the batch transmission successfully transmits k small files at one time, an acknowledgement character (ACK) response is performed. If the transmission fails, all k files are retransmitted.

[0040] An adaptive scenario file transmission method according to an embodiment of the present invention obtains file attributes of files to be transmitted, selects first-category transmission files whose file sizes are smaller than set values ​​according to the file attributes, divides the set of first-category transmission files into several batch transmissions, and performs a confirmation character response after a single batch transmission. After successfully transmitting several first-category transmission files with smaller file sizes in one batch at a time, a confirmation character response is performed again. For massive small files, the process of confirming character responses can be reduced many times, thereby greatly shortening the total time consumed for file transmission.

[0041] In some embodiments, in step S103, the set of first-category transmission files is divided into several batch transmissions, and before a confirmation character response is sent after a single batch transmission, the method further includes:

[0042] Step a1, obtaining the network status of the transmission device.

[0043] Step a2: confirming the number of first-category transmission files in a single batch transmission according to the network status.

[0044] Specifically, the network status includes network delay. Step a2, confirming the number of first-category transmission files of a single batch transmission according to the network status, includes:

[0045] Step a21: if the network delay is greater than the set initial delay, the number of the first type of transmission files in a single batch transmission is reduced.

[0046] Step a22: if the network delay is less than the set initial delay, the number of the first type of transmission files in a single batch transmission is increased.

[0047] During transmission, the size of the batch transmission file number K is adjusted according to the network delay.

[0048] When the network delay is large, that is, greater than the initial delay, the K value should be appropriately reduced to avoid excessive overhead in the number of retransmitted files.

[0049] When the network delay is small, that is, smaller than the initial delay, increase the K value appropriately to ensure that the number of acks is minimized.

[0050] In one example, the network delay can be divided into different areas, and the network delay in each area corresponds to a different K value. As shown in Table 1, when the network delay is between 0ms and 9ms, K is adjusted to 4000, when the network delay is between 10ms and 100ms, K is adjusted to 1000, and when the network delay is greater than 100ms, K is adjusted to 200.

[0051] Table 1 Correspondence between network delay and K value

[0052]

[0053]

[0054] In this way, the number of batch transmissions is dynamically adjusted through network delay, which can reduce transmission interruption or data loss caused by network delay and improve transmission reliability.

[0055] In some embodiments, after obtaining the file attributes of the file to be transmitted in step S101, the following steps are further included:

[0056] Step b1, filtering out the second type of transmission files whose file sizes are greater than or equal to a set value according to the file attributes.

[0057] Specifically, the file size of each file to be transmitted is compared with the set value. When the file size is greater than or equal to the set value, it is classified as a large file, that is, the second type of transmission file. The set value can be set according to the transmission requirements, for example, 1KB, 5KB, 10KB, etc.

[0058] In one example, after filtering out the first category of transmission files as in step S102 , the files other than the first category of transmission files are classified as the second category of transmission files.

[0059] Step b2, determining whether the host resource status of the transmission device is sufficient.

[0060] Specifically, determine whether the host CPU occupancy is less than 80% and it is a multi-core processor. When the host CPU occupancy is less than 80% and it is a multi-core processor, it means that the host resources are sufficient. If the host CPU occupancy is greater than or equal to 80% or it is a single-core processor, it means that the host resource status is insufficient.

[0061] Step b3: if the host resource status is sufficient, the second type of transmission file is divided into blocks according to the set block size to obtain a plurality of file blocks, and the plurality of file blocks are transmitted in parallel.

[0062] Specifically, the block size is set to a preset value, which can be adjusted according to the network status.

[0063] like Figure 3 As shown, the original second-category transmission file is first divided into blocks with a set block size to obtain multiple file blocks, and then the multiple file blocks are transmitted in parallel. After the transmission is completed, the file blocks are reassembled to obtain a complete second-category transmission file.

[0064] Step b4: If the host resource status is insufficient, the second type of transmission files are directly transmitted.

[0065] The host resource status is insufficient. If parallel transmission is performed, it will increase the operating pressure, so direct transmission is performed at this time.

[0066] Currently, large file transfers can fully utilize the bandwidth when the network status is good, but there is still room for optimization. Large file transfers cannot fully utilize the bandwidth when the network status is poor. When the host resources are sufficient, the second type of transfer files can be divided into blocks and then transmitted in parallel to effectively improve bandwidth utilization and shorten transmission time.

[0067] In some embodiments, in step b3, before the second type of transmission file is divided into blocks according to the set block size to obtain a plurality of file blocks, the method includes:

[0068] Step c1, obtaining the network status of the transmission device.

[0069] Step c2, determine the block size according to the network status.

[0070] Specifically, the network status includes the network bandwidth. Step c2, determining the block size according to the network status, includes:

[0071] Step c21, determining whether the network bandwidth is less than the first bandwidth setting value.

[0072] Step c22: if the network bandwidth is less than the first bandwidth setting value, the block size is set to the first preset size.

[0073] Step c23: if the network bandwidth is greater than the first bandwidth setting value, the block size is set to increase in proportion to the network bandwidth, and the block size is not greater than the second preset size.

[0074] Specifically, the first preset size is a default block size, and the first preset size can be set to 1KB, 5KB, 10KB, etc.

[0075] The second preset size is larger than the first preset size. The second preset size is the maximum value of the block and can be set to 0.5MB, 1MB, etc.

[0076] The first bandwidth setting value needs to be preset, for example, it can be set to 4KB, 5KB, etc.

[0077] The file block size is customized according to the network bandwidth. When the network bandwidth is less than the first bandwidth setting value, the first preset size is used. When the network bandwidth is greater than 4MB, the block size increases proportionally, but does not exceed the second preset size.

[0078] By adjusting the block size of the chunks according to the network bandwidth, the transmission bottleneck caused by network bandwidth limitation can be reduced and the transmission speed of large files can be improved.

[0079] In some embodiments, the file attributes also include the file type, and the file type can be determined by the file suffix.

[0080] Before transferring several file blocks in parallel or directly transferring the second type of transfer files, including:

[0081] Step d1, confirming whether the second type of transmission file is a default uncompressed file according to the file type.

[0082] Step d2: If the second type of transmission file is a default uncompressed file, compress the file block or the second type of transmission file.

[0083] Specifically, large file transfers can basically utilize full bandwidth when the network status is good, and the transmission time can be shortened by using compressed transmission methods.

[0084] However, it is worth noting that compression itself consumes resources. When the compressibility ratio of a file is very low, compressed transmission will be counterproductive and increase the transmission time. As shown in Table 2, different types of files have different compression ratios. The ratio of compressed transmission time to original transmission time may be greater than 1 or less than 1.

[0085] Table 2 Correspondence between file type, compression ratio and transmission time

[0086]

[0087] Therefore, different transmission methods need to be adopted according to the file type to effectively shorten the transmission time. In this method, the default file types with low transmission compression such as 7z / zip / jar / gz are used as the set compressed files, and other files except compressed files are the default uncompressed files.

[0088] The compression ratio of the compressed file is set to be relatively low. If the compression is performed, the benefits are low. On the contrary, the compression process takes time, so such files are not compressed for transmission. By default, uncompressed files are transmitted after compression, which can shorten the transmission time.

[0089] Since compression itself consumes resources, when the compressibility ratio of a file is very low, compressed transmission will be counterproductive and prolong the transmission time. Therefore, it is necessary to decide whether to compress based on the file type, which can effectively shorten the transmission time. The default uncompressed file is a file with a relatively high compressibility ratio. Only compressing the default uncompressed file can avoid unnecessary compression and improve the transmission time.

[0090] like Figure 4 As shown, an implementation process of a scene-adaptive file transmission method according to an embodiment of the present invention is as follows:

[0091] 1. Determine the file path of the file to be transferred.

[0092] 2. Scan the entire directory structure and obtain all files and their file attributes, including file size, file type, etc.

[0093] 3. Get the network status, including network bandwidth and network delay, and determine the block size based on the network bandwidth. The default is 1KB, and the block size can be adjusted according to the network bandwidth. For example, if the current network bandwidth is 10MB, confirm that the block size is 2.5KB.

[0094] 4. Filter small files, i.e., the first type of transfer files, and perform batch transfer on the first type of transfer file set. At the same time, periodically obtain the current network delay to adjust the single batch number K. When the delay is 0ms-9ms, adjust K to 4000; when the delay is 10ms-100ms, adjust K to 1000; when the delay exceeds 100ms, adjust K to 200.

[0095] 5. The files to be transferred except the first type of transfer files are regarded as the second type of transfer files. According to the file type of the second type of transfer files, it is determined whether they are default uncompressed files, and whether they are divided into blocks according to the host resource conditions. According to the judgment results, the corresponding transmission methods are adopted respectively, including four transmission methods: block compression, block uncompressed, compression without block, and direct transmission. The block size is determined by step 2.

[0096] The adaptive scene file transmission method of the embodiment of the present invention has the following beneficial effects:

[0097] For the first-class transfer files with smaller file sizes, they are divided into several batch transmissions, and a confirmation character response is performed after a single batch transmission. After several first-class transfer files are successfully transferred in batches at one time, a confirmation character response is performed again. For massive small files, the process of confirming character responses can be reduced many times, greatly shortening the total time consumed in file transfer.

[0098] By dynamically adjusting the number of batch transmissions based on network delays, you can reduce transmission interruptions or data loss caused by network delays and improve transmission reliability.

[0099] By dividing the second type of transfer files into blocks and then transmitting them in parallel, the bandwidth utilization rate can be effectively improved and the transmission time can be shortened. By adjusting the block size according to the network bandwidth, the transmission bottleneck caused by network bandwidth limitation can be reduced and the transmission speed of large files can be improved.

[0100] Deciding whether to compress files based on the file type and only compressing the default uncompressed files before transmitting can avoid unnecessary compression and improve transmission time.

[0101] In summary, the present invention adopts different transmission strategies by autonomously identifying transmission scenarios, including network bandwidth, network delay, file size, file type and other different situations, thereby effectively shortening the transmission time.

[0102] The embodiment of the present invention also provides a scene-adaptive file transmission device, such as Figure 5 As shown, including:

[0105] The batch transmission module 503 is used to divide the set of the first type of transmission files into several batch transmissions, and to respond with a confirmation character after a single batch transmission.

[0106] The adaptive scenario file transmission device of the embodiment of the present invention obtains the file attributes of the files to be transmitted, screens out the first category transmission files whose file sizes are smaller than the set values ​​according to the file attributes, divides the collection of the first category transmission files into several batch transmissions, and performs a confirmation character response after a single batch transmission. After successfully transmitting several first category transmission files with smaller file sizes in batches at one time, a confirmation character response can be performed again. For a large number of small files, the process of confirming character responses can be reduced many times, thereby greatly shortening the total time consumed for file transmission.

[0118] Furthermore, the scene-adaptive file transmission device further includes:

[0119] A second network status acquisition module, used to acquire the network status of the transmission device;

[0120] The block size determination module is used to determine the block size according to the network status.

[0122] A bandwidth determination module, used to determine whether the network bandwidth is less than a first bandwidth setting value;

[0123] A first block size setting module, configured to set the block size to a first preset size if the network bandwidth is less than a first bandwidth setting value;

[0124] The second block size setting module is used to set the block size to increase in proportion to the network bandwidth if the network bandwidth is greater than the first bandwidth setting value, and the block size is not greater than a second preset size.

[0125] Furthermore, the file attribute also includes the file type, and the scene-adaptive file transmission device also includes:
