Based on the hardware structure of the equipment, the embodiment of the file transmission method is provided.
It should be noted that the file transmission method provided by the present invention is applied to file transmission between networks and file transmission between terminals, and also includes file transmission between networks and terminals; the equipment involved in the file transmission process does not only comprise a file sending terminal and a file receiving terminal, but also can be additionally provided with a forwarding server between the file sending terminal and the file receiving terminal, so that the file sent from the file sending terminal to the file receiving terminal is forwarded through the forwarding server. It is to be understood that the present invention is not limited to the type of file transferred.
Referring to fig. 2, in the first embodiment of the file transfer method of the present invention, the file transfer method includes steps S10 through S30:
step S10, when receiving a file transmission request initiated by a sending end, obtaining a target file and a target communication end point corresponding to the file transmission request;
first, the sending end mentioned in this embodiment may be a network (e.g., a local area network) or a device (e.g., a personal computer), and the file type sent by the sending end may be a document, a picture file, a video file, or an installation package file.
When a system receives a file transmission request initiated by a sending end, a target file and a target communication endpoint corresponding to the file transmission request are obtained, the target file is a file transmitted by the sending end, the target communication endpoint can be simply understood as an abstract endpoint, the sending end and the receiving end both have communication endpoints (the target communication endpoint mentioned in this embodiment refers to a communication endpoint of the sending end in particular), the target communication endpoint includes an IP address and a port number, and the communication endpoint of the sending end includes an IP address and a port number of the receiving end. It can be understood that the speed of file transmission is fast, so there is no situation that the IP address and (available) port number of the receiving end change during the file transmission process, even if the above situation occurs, the IP address and the available port number of the receiving end included in the target communication end point can be timely adjusted through a feedback mechanism, the feedback mechanism is an instant information sharing mechanism between the sending end and the receiving end, when the receiving end switches the IP address through the IP switching server for a second, the receiving end sends the information of IP address switching to the sending end or a forwarding server between the receiving end and the sending end through the feedback mechanism, so as to change the IP address and the available port number of the receiving end included in the target communication end point.
Step S20, sequentially carrying out segmentation processing and compression processing on the target file to obtain a compressed target segmented file;
it should be noted that, the file transmission method proposed by the present invention is intended to implement faster remote file transmission, and when a file is large (meaning that the space occupied by the file is large), the transmission speed of the file is liable to be affected. The file compression means that repeated parts in file contents are replaced by special characters, the repeated parts represented by the special characters are placed in a dictionary file and are sent to a receiving end along with the compressed file, and after the receiving end receives the compressed file and the dictionary file, the file is decompressed according to the contents recorded in the dictionary file to obtain a target file.
And step S30, transmitting the compressed object segmentation file to a receiving end corresponding to the object communication endpoint through the object multithreading corresponding to the transmitting end.
It should be noted that, a plurality of small files are obtained after splitting the target file, and the compressed target split file is transmitted to a receiving end corresponding to a target communication end point through multiple threads corresponding to a transmitting end, where each thread in the target multiple threads is responsible for transmitting one target split file, when a forwarding server exists between a transmitting end and a receiving end of the target file, the receiving end in this embodiment is the forwarding server, and the target communication end point includes an IP address and a receivable port of the forwarding server.
Further, in a possible embodiment, the method for service maintenance is applied to a client terminal, and in step S10, when a file transfer request initiated by a sender is received, a target file and a target communication endpoint corresponding to the file transfer request are obtained, and the following steps include:
a1, acquiring the transmission frequency range and signal-to-noise ratio of a target transmission channel between the sending end and the receiving end corresponding to the target communication end point;
a2, compressing the target file, and calculating the byte size of the compressed target file;
step a3, determining whether to segment the target file according to the transmission frequency range, the signal-to-noise ratio and the byte size.
It should be noted that, the transmission frequency range of the transmission channel affects the transmission success rate of the file, and the signal-to-noise ratio of the transmission channel affects the transmission rate of the file, specifically, the medium-channel for information (i.e. file) transmission is not ideal, and the information transmitted through the channel is interfered and distorted, so how to reduce the degree of interference during information transmission determines the degree of information distortion, the larger the degree of information distortion is, the lower the transmission success rate is, specifically, the pulse signal corresponding to the transmission information is a symbol, the waveform of the symbol is affected and changed by the symbol transmission speed, signal transmission distance, noise interference and transmission medium quality, when the waveform is changed greatly, the waveform distortion is more serious at the receiving end of the channel, and the transmission rate of the symbol is affected by the frequency range through which the channel can pass (i.e. the transmission frequency range of the channel), the signal transmitted on the channel (i.e. the pulse signal corresponding to the transmission file) is actually formed by performing multiple harmonics on analog signals with multiple frequencies, and the larger the transmission frequency range of the channel is, the lower the distortion degree of the pulse signal corresponding to the transmission file is, and the higher the transmission success rate of the file is.
Similarly, if the channel is required to transmit information faster, one symbol is required to carry more bit information, and as is known, a binary symbol, one symbol represents one bit; octal symbols, one symbol representing three bits; the hexadecimal code element, a code element represents four bits, because the noise is produced randomly, the instantaneous value of the noise is very large sometimes, under the condition of certain voltage range, the difference between the hexadecimal code element waveforms is smaller than that between the octal code element waveforms, because of the noise interference, when the real channel is transmitted, the code element waveform difference is too small, the receiving end is not easy to clearly identify, and the success rate of information transmission is low.
The method includes the steps of compressing a target file, calculating the byte size of the compressed target file, drawing a pulse signal corresponding to the target file, and determining whether to divide the target file according to the pulse signal corresponding to the target file, the transmission frequency range and the signal-to-noise ratio of a target transmission channel.
Further, in a possible embodiment, the step a3 determines whether to perform the segmentation process on the target file according to the transmission frequency range, the signal-to-noise ratio and the byte size, and the step of refining includes:
b1, acquiring a target transmission signal corresponding to the target file, and performing harmonic processing on the target transmission signal through preset high-frequency waves;
step b2, if the frequency of the target transmission signal obtained after the harmonic processing does not belong to the transmission frequency range, or the transmission code element corresponding to the target transmission signal is not matched with the signal-to-noise ratio, or the byte size is larger than a preset threshold, determining to segment the target file.
It is known that, the frequency of the target transmission signal corresponding to the target file is the fundamental wave, the fundamental wave and the higher frequency harmonic wave are increased to be superimposed to obtain the target transmission signal after harmonic processing, and it should be noted that all channels have respective allowable frequency ranges, when the preset high frequency wave is larger, the high frequency wave included in the target transmission signal obtained after harmonic processing cannot pass through the channel, thereby causing distortion of the transmission signal, when there are more high frequency waves that cannot pass through the channel in the target transmission signal (indicating that the frequency of the target transmission signal obtained after harmonic processing does not belong to the transmission frequency range of the target transmission channel), severe distortion of the transmission signal is generated, and the smaller the signal-to-noise ratio, the larger the scale of the allowed symbol is, i.e. the faster the transmission rate of the allowed symbol is allowed to pass through, and the larger the scale of the transmission symbol corresponding to the target transmission signal is, when the signal-to-noise ratio is smaller, the transmission code element corresponding to the target transmission signal is not matched with the signal-to-noise ratio, or the byte size of the compressed target file is still larger than a preset threshold value, and then the target file is determined to be segmented.
Further, in a possible embodiment, in the step S30, the compressed target split file is transmitted to the receiving end corresponding to the target communication end point through the target multithreading corresponding to the sending end, and the step of refining includes:
step S31, according to the transmission frequency range and/or the signal-to-noise ratio, the target transmission channels are sequenced to obtain a channel sequencing result;
step S32, based on the channel sorting result, establishing the incidence relation between the compressed target segmentation file and the target transmission channel;
and step S33, transmitting the compressed target division file to a receiving end corresponding to the target communication end point through the target multithreading corresponding to the transmitting end and the incidence relation.
It should be noted that, when there are multiple target transmission channels, all the target transmission channels may be sorted according to the transmission frequency range and/or the signal-to-noise ratio to obtain a channel sorting result, and it is known that all the target transmission channels may be sorted from large to small based on the size of the transmission frequency range; all the target transmission channels can be sequenced from small to large based on the magnitude of the signal-to-noise ratio, and certainly, the target transmission channels can also be sequenced by comprehensively considering the transmission frequency range and the signal-to-noise ratio to obtain a channel sequencing result, and the target transmission channel at the front in the sequencing result has higher transmission rate and transmission success rate, so that the incidence relation between the compressed target segmentation file and the target transmission channel can be established based on the importance degree, namely, the more important target segmentation file is transmitted through the target transmission channel at the front in the sequencing result.
In this embodiment, when a file transmission request initiated by a sending end is received, a target file and a target communication endpoint corresponding to the file transmission request are obtained, then the target file is sequentially subjected to segmentation processing and compression processing to obtain a compressed target segmented file, finally the compressed target segmented file is transmitted to a receiving end corresponding to the target communication endpoint through target multithreading corresponding to the sending end, and the target file is segmented and compressed to finally transmit the target file through multithreading, so that the file transmission rate is improved.
Further, referring to fig. 3, a second embodiment of the file transfer method of the present invention is proposed on the basis of the above-mentioned embodiment of the present invention.
This embodiment is a step of the first embodiment, which is a refinement of step S20, and the difference between this embodiment and the above-described embodiment of the present invention is step S21-step S22:
step S21, based on the preset time dependence degree and the number of the target transmission channels, the target file is segmented to obtain segmented files;
and step S22, compressing the divided files to obtain compressed target divided files.
It can be known that, when the content included in the target file has different time dependency degrees (that is, the content included in the target file needs to be sent in chronological order, and the content sent first has a higher time dependency degree), the target file is divided based on the preset time dependency degree and the number of the target transmission channels to obtain a divided file, specifically, if the number of the target transmission channels (in an idle state) is 5, it is determined that the target file needs to be divided into 5 small files, where the specific content included in each of the divided small files is determined by the time dependency degree corresponding to the content included in the target file, and therefore, the sizes of the content (capacity) included in the divided files may be different. And finally, compressing the divided files to obtain the compressed target divided files.
Further, in a possible embodiment, in the step S22, the step of compressing the divided files to obtain the compressed target divided file, and the step of refining includes:
step c1, replacing continuous same data in the segmented file with preset characters to obtain a replaced segmented file, wherein the capacity of the preset characters is smaller than the continuous same data;
and c2, generating a dictionary file corresponding to the segmentation file, recording the preset characters and the positions of the preset characters in the segmentation file in the dictionary file, and taking the segmentation file after replacement and the dictionary file as compressed target segmentation files.
It can be understood that when compressing the divided files, two points need to be paid attention to, namely, the size of the capacity of the compressed divided files plus the corresponding 'dictionary' files should be smaller than that of the divided files before compression, and each compressed divided file corresponds to a dictionary file. Firstly, replacing continuous and same data in the divided file with a preset character, wherein if the continuous and same data in the divided file is '11111', the preset character can be '51' and represents 5 continuous 1, and it should be noted that in this case, at least more than 3 continuous data exist for compression, the information that the preset character '51' represents '11111' is stored in the dictionary file, and the position information of '11111' in the divided file is also included, and the divided file and the dictionary file after replacement are taken as a compressed target divided file.
In this embodiment, the target file is divided based on the preset time dependency and the number of the target transmission channels, and then the divided files are compressed, so that the file transmission rate is increased.
In addition, referring to fig. 4, an embodiment of the present invention further provides a file transmission apparatus, where the file transmission apparatus includes:
the system comprises an acquisition module, a sending module and a communication module, wherein the acquisition module is used for acquiring a target file and a target communication endpoint corresponding to a file transmission request when receiving the file transmission request initiated by a sending end;
