Chinese Internet Data Compression Of Single Character Encoding Optimization Method Research And Implementation

How to quickly obtain information from the network to attract attention.On the basisof existing network equipment,how to improve the data transferrate becoming a hotresearch topic in particular. Internet data compression is a feasible direction canimprove the data transfer rate, but the existing compression algorithms targeted Internetdata transmission coded by ASCII.These rarely targeted Chinese-encoded Internet.Universal data compression, there are compression algorithms difficult to improve itscompression performance.This thesis contrapose the Characteristics of transmission ofdata and compression theory of existing algorithms, improvement of the existingalgorithm is a feasible direction. This is the direction of this thesis.This thesis is more comprehensive in-depth research and analysis of the compressionalgorithm, Applied to the Internet data compression. A comparative study targetedcompression principle.Characteristics of Chinese Internet data coding, and tested onexisting compression algorithm to do the performance test. Through the analysis ofthese studiesand experiments on a test the compression algorithm and by improving theunmatch single character encoding, improved compression algorithm and not spend toomuch time. In this thesis, in addition to study the existing algorithms, but also acomparative study targeted the compression algorithm is applied to the specificcombination of Internet data compression. Combined with improved compressionalgorithm, the application prototype is simulated.The main content of this thesis: Study the compression principle of existingcompression algorithm used in Internet data compression, In particular, the algorithm ofunmatch single character encoding. According to the compression algorithm principle,writing the encoding of existing compression algorithms, building the algorithmcomparison test experimental platform, grabing the test data samples from the ChineseInternet, testing the performance of existing algorithms, combining with LZJHalgorithm,targeted the algorithmof unmatch single character to do the performance test.targeted the unmatch single character encoding of algorithm and data characteristics of the Chinese Internet,proposing the optimization algorithm of single character encoding.It is the innovation of this thesis.Giving the way of combining the optimizationalgorithm with existing algorithms and the theoretical analysis for the improvedalgorithm. Finally, this thesis gives the way of combining the optimization algorithms ofsingle character encoding whith LZJH. Through the comparison test experimentofimproved LZJH and existing algorithm, proving the feasibility of the proposedalgorithm. Combining with HTTP compression prototype and using the OPNETnetwork simulation software, optimize LZJH algorithm of combining with singlecharacter encoding applied to the HTTP compression prototype.A prototype systemtargeted HTTP compression testing and analysis in OPNET simulation environment. Inaddition to the research the algorithm, this thesis also studied and implemented:Separation out of the experimental test samples from data exported by the packetcapture software. Researching the router’s routing algorithm of the RIP protocol andDNS protocol.building the domain server.
