File compression algorithm selection method based on capability negotiation

Abstract

The invention discloses a capability negotiation-based file compression algorithm selection method, which comprises the following steps of: compressing a test file by using all compression algorithms in a first compression module to generate a test file compression package, and recording compression time as first duration; all the generated test file compressed packages are sent to a file receiving end, and the file receiving end decompresses the related test file compressed packages by adopting corresponding compression algorithms in a second compression module and records respective decompression time as second duration; the second duration is sent to the file sending end, the file sending end adds the first duration and the second duration corresponding to the same compression algorithm, and the sum is recorded as the total duration; and selecting the compression algorithm with the minimum total duration as the compression algorithm for subsequent file compression and decompression. According to the method, the optimal compression algorithm can be selected according to the specific processing capacity of the file sending end and the file receiving end, and rapid compression and decompression of the file are achieved.

Description

technical field [0001] The invention relates to the field of file transmission, in particular to a method for selecting a file compression algorithm based on capability negotiation. Background technique [0002] Currently, in a file transmission system, data is usually compressed before transmission to facilitate data transmission. In the prior art, the same compression algorithm is usually used on different platforms. However, since the compression and decompression performance of different compression algorithms on different platforms are quite different, if the performance of the specific platform itself is not selected The optimal compression algorithm cannot make full use of the machine processing power of the platform, resulting in slow file compression and decompression speed. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the...
