It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 is a schematic flowchart of a file transmission method provided in an embodiment of the present invention, which is applied to a sending end located in a first secure area, and as shown in fig. 1, the method includes the following steps:
step 101: acquiring a file to be transmitted, and determining a first parameter of the file to be transmitted, wherein the first parameter at least represents the data volume of the file to be transmitted;
it is to be understood that the first safety zone may be a management information large zone in the power automation system, and specifically, may be a safety three zone; the second safety zone may be a production control zone in the electric power-driven system, and specifically, may be a safety first zone or a safety second zone, wherein a power-dedicated transverse unidirectional safety isolation device certified by detection of a country-specific department must be provided between the production control zone and the management information zone. The reverse safety isolation device is used for unidirectional data transmission from the safety three area to the safety first area or the safety second area.
The file to be transmitted may specifically be unstructured data such as web pages, images, audio, video and the like from an external data source. The first parameter may be a file size of a file to be transmitted, specifically, for example, the file to be transmitted is a picture, and the first parameter may represent a data amount of the picture, 1M.
Step 102: determining a target file sending queue based on the first parameter and a threshold condition corresponding to the alternative file sending queue, and adding the file to be transmitted into the target file sending queue;
here, the threshold condition corresponding to the candidate file sending queue refers to that each candidate file sending queue sets a corresponding data amount, and the candidate file sending queue corresponding to the first parameter is determined by comparing the data amount with the first parameter, for example, the candidate file sending queue includes an a sending queue and a B sending queue, the threshold condition of the a sending queue is 0-5M, the threshold condition of the B sending queue is greater than 5M, and if the data amount corresponding to the first parameter is 0.5M, the target file sending queue is determined to be the a sending queue, and the file to be transmitted is added to the a sending queue. Thus, large files are added to the B send queue and small files are added to the A send queue.
Step 103: and sending the file to be transmitted to a receiving end positioned in a second safety area according to an operation strategy corresponding to the target file sending queue, wherein the second safety area is different from the first safety area, and the data volume sent to the receiving end by the file to be transmitted at one time is positioned in a preset range.
It can be understood that different target file sending queues correspond to different operation strategies, and the operation strategies may be parallel transmission of the files to be transmitted or whole transmission of the files to be transmitted to the receiving end of the second security area.
The fact that the data volume sent to the receiving end by sending the file to be transmitted at one time is within a preset range means that the data volume sent by the file to be transmitted at one time is within a preset range, for example, the preset range is 10M, and the data volume of the file to be transmitted sent to the receiving end at one time is less than or equal to 10M.
According to the embodiment of the application, a first parameter of a file to be transmitted is determined by acquiring the file to be transmitted, and the first parameter at least represents the data volume of the file to be transmitted; determining a target file sending queue based on the first parameter and a threshold condition corresponding to the alternative file sending queue, and adding the file to be transmitted into the target file sending queue; thus, different files to be transmitted are added into the corresponding target file sending queue based on the size of the data volume; and sending the file to be transmitted to a receiving end positioned in a second safety area according to an operation strategy corresponding to the target file sending queue, wherein the second safety area is different from the first safety area, and the data volume sent to the receiving end by the file to be transmitted at one time is positioned in a preset range. Therefore, different target file sending queues are added to files to be transmitted with different data volume sizes, and the data volume of each file to be transmitted is ensured to be within a preset range based on the preset range of the set data volume, so that the files to be transmitted are ensured to be transmitted quickly, stably and reliably.
In one embodiment, the target file send queue comprises a slice send queue; the determining a target file sending queue based on the first parameter and a threshold condition corresponding to the alternative file sending queue, and adding the file to be transmitted into the target file sending queue includes:
comparing the first parameter with a threshold condition corresponding to an alternative file sending queue, and determining that the first parameter meets a first threshold corresponding to the slice sending queue;
generating a plurality of slices to be transmitted with the data volume within the preset range based on the file to be transmitted;
and adding the plurality of slices to be transmitted into the slice sending queue.
And determining that the first parameter meets a first threshold corresponding to the slice sending queue by comparing the first parameter with a threshold condition corresponding to the alternative file sending queue, namely determining that the target file sending queue is the slice sending queue and adding the file to be transmitted into the slice sending queue if the threshold condition of the slice sending queue is greater than 5M and the data volume corresponding to the first parameter is 10M.
Generating the to-be-transmitted slice with the data volume within the preset range based on the to-be-transmitted file means that the to-be-transmitted file is sliced into a plurality of to-be-transmitted slices meeting the preset range, for example, if the preset range is 10M and the to-be-transmitted file is 30M, 10 3M to-be-transmitted slices are generated, and the to-be-transmitted slices are added into a slice sending queue.
It should be noted that, in addition to slicing the file to be transmitted, the file to be transmitted may also be compressed, the file is cut into a plurality of slices to be transmitted according to the size of the compressed file, and then each slice to be transmitted is encoded to form a plurality of slices to be transmitted that meet the reverse transmission specification.
In the embodiment, the first parameter is compared with the threshold corresponding to the alternative file sending queue, the first threshold meeting the slice sending queue is determined, the file to be transmitted is generated into a plurality of slices to be transmitted meeting the preset range, and the slices to be transmitted are added into the slice sending queue.
In an embodiment, the sending the file to be transmitted to a receiving end located in a second secure area includes:
and sending the to-be-transmitted slice corresponding to the to-be-transmitted file to the receiving end positioned in a second safety zone.
It can be understood that the slice to be transmitted corresponding to the file to be transmitted includes at least two slices to be transmitted, and specifically, the number of slices to be transmitted depends on the first threshold set by the slice transmission queue and the size of each slice to be transmitted. In the process of transmitting a file from a safety three area to a safety one area or a safety two area in a cross safety area, the step of sending slices to be transmitted to a receiving end positioned in a second safety area means that a plurality of slices to be transmitted are averagely grouped according to the number of reverse transmission links, are put into reverse isolation transmission catalogues corresponding to all the reverse links, and are transmitted to the receiving end through a reverse isolation device in parallel by sending the catalogues through the reverse isolation. Thus, parallel transmission of the slices to be transmitted is realized.
In an embodiment, the method further comprises:
sending a first identification parameter of the file to be transmitted, wherein the first identification parameter comprises: the file identification to be transmitted, the information abstract of the file to be transmitted, the total number of the slices to be transmitted corresponding to the file to be transmitted and the serial number of the slices to be transmitted.
Here, the sent file to be transmitted carries the first identification parameter, the file to be transmitted identifies an original file name of the file to be transmitted, and the information digest of the file to be transmitted may be an information digest of the file to be transmitted generated by an MD5Message digest algorithm (MD5 Message-DigestAlgorithm). The MD5message digest algorithm is a widely used cryptographic hash function that generates a 128-bit (16-byte) hash value to ensure the integrity of the message transmission.
In this way, the uniqueness of the file name is ensured through the file identifier (original file name) to be transmitted and the information abstract (original file MD5) of the file to be transmitted, and meanwhile, whether the file merged by the receiving end is complete is verified through MD5, and the total number of the slices to be transmitted corresponding to the file to be transmitted and the serial number of the slices to be transmitted are used for determining the total number of the slices to be transmitted and the merging sequence of the slices to be transmitted when the slices to be transmitted are merged.
In one embodiment, the target file send queue comprises a set send queue; the determining a target file sending queue based on the first parameter and a threshold condition corresponding to the alternative file sending queue, and adding the file to be transmitted into the target file sending queue includes:
comparing the first parameter with a threshold condition corresponding to an alternative file sending queue, and determining that the first parameter meets a second threshold corresponding to the set sending queue;
generating a file set containing the file to be transmitted, wherein the data volume of the file to be transmitted is within the preset range;
and adding the file set into a set sending queue.
And determining that the first parameter meets a second threshold corresponding to the set sending queue by comparing the first parameter with a threshold condition corresponding to the alternative file sending queue, namely determining that the target file sending queue is the set sending queue and adding the file to be transmitted into the set sending queue if the threshold condition of the set sending queue is less than 10M and the data volume corresponding to the first parameter is 0.5M.
Generating a file set containing transmission files with data volume within the preset range based on the files to be transmitted refers to generating a plurality of file sets to be transmitted into a file set of the files to be transmitted, wherein the data volume of the file set meets the preset range.
Here, the set sending queue may set a timeout time, where only one file to be transmitted exists within the timeout time, the file to be transmitted is sent as a file set, and if there are multiple files to be transmitted within the timeout time, a file set including the multiple files to be transmitted is generated, where the data size of the file set is within the preset range. For example, if the preset range is 3M and the file to be transmitted is 0.3M, a file set composed of 10 files to be transmitted of 0.3M is generated, and the file set is added to the set sending queue.
It should be noted that, in addition to aggregating the files to be transmitted, the files to be transmitted may also be compressed, the multiple compressed files are generated into an aggregate file according to a preset range according to the size of the compressed files, and then the aggregate file is encoded to form an aggregate file conforming to the reverse transmission specification.
In the embodiment, the second threshold value meeting the set sending queue is determined by comparing the first parameter with the threshold value corresponding to the alternative file sending queue, the file set containing the file to be transmitted and having the data volume within the preset range is generated based on the file to be transmitted, and the set is added into the set sending queue, so that the small file slices to be transmitted are combined and transmitted, the frequent transmission of the small files is avoided, and the transmission efficiency is greatly improved.
In an embodiment, the sending the file to be transmitted to a receiving end located in a second secure area includes:
and sending the file set to the receiving end positioned in the second safety area.
It can be understood that the aggregate file is composed of a plurality of files to be transmitted, in the process of transmitting the files from the security three area to the security one area or the security two area across the security area, the transmission of the aggregate to the receiving end positioned in the second security area means that an aggregate file conforming to the reverse transmission specification is generated by combining a plurality of files to be transmitted, and the aggregate file is randomly placed into a reverse isolation transmission directory corresponding to a reverse link for transmission, so that the combined aggregate transmission of the aggregate file combined by the plurality of files to be transmitted is realized, and the transmission efficiency is greatly improved.
In an embodiment, the method further comprises:
sending a second identification parameter of the file set, wherein the second identification parameter comprises: the file to be transmitted comprises the file identification to be transmitted, the information abstract of the file set and the total number of the files to be transmitted which form the file set.
Here, the sent file set carries the second identification parameter, the identification of the file to be transmitted may include an original file name of the file to be transmitted, and the information digest of the file to be transmitted may be an information digest of the file to be transmitted generated by an MD5Message digest algorithm (MD5 Message-DigestAlgorithm). The MD5message digest algorithm is a widely used cryptographic hash function that generates a 128-bit (16-byte) hash value to ensure the integrity of the message transmission. Here, the size of the file to be transmitted may also be included for further verifying each file to be transmitted.
Here, the uniqueness of the file name is ensured by the aggregate file MD5, and meanwhile, whether the aggregate file received by the receiving end is complete is verified by the MD5, and further, when a plurality of files to be transmitted are merged into an aggregate file, the information of each file to be transmitted is stored in order at the header of the aggregate file, which includes: the file identification to be transmitted and the information abstract of the file to be transmitted are used for separating and restoring each file to be transmitted from the aggregate file.
The technical solutions of the embodiments of the present invention are further described below by specific examples.

With reference to fig. 3, the specific operation flow of the file transmission method is as follows:
step S1: scanning a file distribution service program;
here, the file distribution service program is located in the receiving end and used for receiving a file sending request and acquiring a file to be transmitted;
step S2: acquiring a file to be transmitted;
step S3: comparing the file size with a threshold;
if the file size meets the first threshold of the slice sending queue, the file is a large file, and the step is switched to step S4; if the file size meets the second threshold of the set sending queue, the file is a small file, and the step is turned to step S9;
step S4: putting the slices into a slice sending queue;
step S5: taking out a file to be transmitted from the queue;
step S6: compressing, slicing and encoding;
step S7: forming a group of slices to be transmitted;
here, after compressing, slicing and encoding are performed to form a plurality of slices to be transmitted that meet the reverse transmission specification, average packets are put into the sending-end directories of each reverse transmission link, and large files are sent in parallel, that is, step S8 is performed.
Step S8: putting the packets into a reverse isolation sending directory;
here, after the packet is placed in the reverse isolation transmission directory, step S14 is executed.
Step S9: putting the data into a set sending queue;
step S10: taking out a group of files to be transmitted from the set within the overtime time;
setting a smaller timeout time to ensure that a certain number of files (small files) to be transmitted exist in the set sending queue, wherein the timeout time is not too long, otherwise, the existing transmission task in the set sending queue is delayed;
step S11: compressing, combining and encoding;
step S12: forming a collection file;
step S13: randomly putting a reverse isolation sending directory;
step S14: the reverse isolation device transmits to the secure first zone directory.
In this way, the file to be transmitted is sent to the receiving end located in the second security zone, specifically, referring to fig. 4, after the receiving end receives the file to be transmitted, the specific operation flow of the file receiving method is as follows:
step S101: scanning a file distribution service program;
here, the file distribution service program is located in a receiving end of the first secure area and is used for scanning a file to be transmitted, which is sent by the sending end;
step S102: taking out the file to be transmitted from the reverse isolation receiving directory;
step S103: judging the file type according to the file identifier to be transmitted;
here, the file type may be determined according to the identifier of the file to be transmitted, or may be determined by naming the transmission file, for example, placing the "slice" extension file of the sliced file to be transmitted into the slice file receiving queue, and placing the "set" extension file into the aggregate file receiving queue; if the extension file is a 'slice' extension file, executing the step S104, and if the extension file is a 'set' extension file, executing the step S109;
step S104: putting the slices into a slice receiving queue;
step S105: waiting for all slices of the file to be transmitted to enter a queue;
step S106: decoding, merging and decompressing;
here, compression, slicing, encoding of the file in the secure area corresponds.
Step S107: restoring the file to be originally transmitted;

And the safe first-region aggregate file receiving service program reads a single file to be transmitted in the aggregate receiving queue, decodes the single file to be transmitted, splits the decoded file into a plurality of files according to second identification information corresponding to the aggregate file recorded at the head of the file, decompresses the files to form original small files to be transmitted, verifies each file to be transmitted MD5, and transmits each file to a corresponding receiving program after the verification is passed.
In the embodiment of the invention, a reverse file sending end and a reverse file receiving end are added on the basis of the existing reverse trans-regional transmission mode, and a strategy of 'small file compression, merging and transmission and large file compression, slicing and concurrent transmission' is adopted according to the size of a file to be transmitted, so that on one hand, small files are merged and transmitted, and the working efficiency of a reverse isolation device is improved; on the other hand, the large file slices are transmitted concurrently, the transmission speed of the large file is accelerated to be isolated in a reverse direction, and the transmission reliability of the large file is improved.
