Embodiment Construction

[0036] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0037] see figure 1 , the present invention provides a kind of transmission method of large data amount file, comprises the following steps:

[0038] S1. At the sending end of the file transfer, the file to be sent is divided into blocks to obtain a sending sub-file block and a waiting sub-file block, and while generating the sending sub-file block, it is verified according to the agreement with the receiving end the number of bytes to generate the first verification information of the sending sub-file block;

[0039] S2. Transmit the sending sub-file block and the first verification information to the receiving end; wherein, the sending sub-file block is transmitted to the receiving end in the form of stream transmission;

[0040]S3. Du...

Abstract

The invention provides a method and a system for transmitting files with large data sizes. The method for transmitting the files with large data sizes comprises the following steps of step one, processing the files to be transmitted in blocks at a transmitting end of file transmission and generating first verification information of transmission sub-file blocks while generating the transmission sub-file blocks; step two, transmitting the transmission sub-file blocks and the first verification information to a receiving end; step three, generating second verification information every time data of verified bytes agreed with the transmitting end at the receiving end; step four, comparing the second verification information with the received first verification information, and transmitting corresponding information to the transmitting end; step five, after the transmitting end receives the information transmitted by the receiving end, enabling the transmitting end to transmit obtained requests of receiving positions of the files at the receiving end when last transmission is stopped or finished; and step six, judging whether the receiving positions of the files reach the end of the files to be transmitted according to the information returned by the receiving end.

Description

technical field [0001] The invention relates to the field of computer networks and file transmission technology, in particular to a method and system for transmitting files with a large amount of data for media asset management. Background technique [0002] At present, the media assets managed by media assets are generally files with a very large amount of data, almost all of which are in gigabytes, and the data are very precious, so when using the network to transmit these files, the following two points need to be guaranteed: 1. To ensure the integrity of the material; 2. Due to the large amount of data in the file, it is necessary to increase the file verification. [0003] There are two types of file transmission methods commonly used in the prior art: block transmission (block transmission for short) and streaming transmission (stream transmission for short). [0004] Block transfer: refers to each time a data block is transferred, the server performs verification whe...
