Problems solved by technology

The theoretical peak value of gigabit network transmission is 128MBytes / second. Without processing the original data, it is obvious that gigabit network can no longer meet the data transmission requirements of this scale.
[0004] To meet the data transmission requirements of the business scale, the current method of compressing the original file and then transmitting it is adopted, but the compression efficiency of large files is very low. After compressing a large file, it is transmitted from the sender to the receiver, and then the file is decompressed. Efficiency still cannot meet the data transmission requirements of business scale

Embodiment 1

[0034] This embodiment discloses a method for sending and receiving files, such as figure 1 As shown, the method includes:

[0035] Splitting the file into multiple data packets; compressing the multiple data packets at the same time; sending the compressed multiple data packets at the same time;

[0036] Receive the compressed data packets; decompress the received data packets; store the decompressed data packets.

[0037] Wherein, said splitting the file into multiple data packets includes: sequentially splitting the file into multiple data packets.

[0038] Preferably, the method further includes: configuring identification information, and the identification information is used to identify each data packet.

[0039] Wherein, the storing the decompressed data packets includes: sequentially storing the decompressed data packets according to the identification information.

[0040] Preferably, the method further includes: judging whether the file is received successfully, ...

Embodiment 2

[0042] This embodiment discloses a multi-file sending and receiving method, such as figure 2 As shown, the method includes:

[0043] Configure the identification information according to the adapter configuration table at the sending end;

[0044] Scan the file to be sent from the file storage disk and read the file. In this embodiment, file A and file B are read;

[0045] Sequentially split file A into three data packets, and sequentially split file B into two data packets;

[0046] Compress the five data packets obtained at the same time. In this embodiment, considering the sending and receiving of file A, the three compressed data packets of file A are marked as 1, 2, and 3 according to the identification information;

[0047] Send the compressed five data packets at the same time;

[0048] Five data packets arrive at the receiving end through the transmission of the transmission middleware;

[0049] Simultaneously receive five compressed data packets;

[0050] Accord...

Embodiment 3

[0056] This embodiment discloses a method for sending and receiving a single file, such as image 3 As shown, the method includes:

[0057] Read the file from the sending disk;

[0058] Sequentially split the file into six packets;

[0059] Configuring identification information, the identification information identifies the above six data packets as 1, 2, 3, 4, 5, 6;

[0060] Simultaneously compress the obtained six data packets in parallel;

[0061] Send the compressed six data packets at the same time;

[0062] The six data packets arrive at the receiving end through the transmission of the transmission middleware;

[0063] According to the identification information, serially receive the compressed six data packets;

[0064] Decompress the received six packets;

[0065] Write the decompressed data packets to the receiving end disk sequentially;

[0066] Preferably, the method further includes: judging whether the file is received successfully, if the file is success...

Abstract

The invention discloses a file receiving and sending method and system. The method comprises the following steps: splitting a file into a plurality of data packets; compressing the plurality of data packets simultaneously; transmitting the plurality of compressed data packets simultaneously; receiving the plurality of compressed data packets; decompressing the plurality of received data packets; and storing the decompressed data packets.

Description

technical field [0001] The invention relates to the field of data transmission, and specifically relates to a file sending and receiving method and system. Background technique [0002] In order to adapt to file transfer application scenarios, some commercial transfer products provide file transfer functions through application layer encapsulation on the basis of basic buffer transfer functions. [0003] With the continuous development and expansion of the business scale of the application layer, ordinary file transfer functions (including the ftp that comes with the operating system, and various commercial transfer products that support file transfer functions) have gradually shown signs that they cannot meet the needs of business scale. . For example, in organizations like provincial mobile companies, the scale of online call bill data file transfer is expected to reach tens of TBytes per day in the next two years, and the peak data transfer volume can reach 500MBytes / sec...
