An efficient compression method for fsn files

Abstract

The invention discloses a method for efficiently compressing full service network (FSN) files, which is an efficient compression method which is obtained by adopting specific lossless compression to process FSN files generated through equipment a byte stream mode. The method for efficiently compressing FSN files can upload the FSN files generated through the equipment through a file transfer protocol (FTP) after the FSN files generated through the equipment are compressed to be a proportion. The method for efficiently compressing FSN files greatly reduces processing pressure on equipment ends, reduces transmission flow during the network transmission process, greatly improves uploading speed and uploading amount of files, and reduces bandwidth requirements and network pressure.

Description

technical field [0001] The invention relates to a technique for compressing by reading byte streams during file transmission, in particular to a compression method for performing specific algorithm rules on binary strings of byte streams, and belongs to the technical field of compression. Background technique [0002] Data compression is a cutting-edge technology involving communication principles and computer science. In communication principles, it is generally called source coding. In computer science, it is generally called data compression. There is no difference between the two in essence, they are both mapping. [0003] On the one hand, when communicating, it is necessary to compress the data to be transmitted to reduce bandwidth requirements; on the other hand, when the computer stores data, in order to reduce the disk capacity requirements, files are also compressed, although the current network The bandwidth is getting higher and higher, and compression is not as u...

Problems solved by technology

[0003] On the one hand, when communicating, it is necessary to compress the data to be transmitted to reduce bandwidth requirements; on the other hand, when computers store data, in order to reduce disk capacity requirements, files are also compressed, although the current network The bandwidth is getting higher and higher, and compression is not as urgent as it was in the early 1990s, but it is still needed in many occasions. One of the reasons is that after the compressed data capacity is reduced, the time for disk access IO is also shortened. Although compression and decompression The compression process consumes CPU resources, but the CPU computing resources increase rapidly, but the disk IO resources change very slowly. For example, the current mainstream SATA hard disk is still 7200 rpm. If the IO pressure of the disk is transferred to the CPU, the overall Can increase system speed
