The Design Of Server Based On FTP Protocol And Its Transmission Performance Optimization

With the rapid development of Internet technology and data storage technology,network data transmission plays a more and more important role.FTP protocol is currently used in many data transmission fields.It has the characteristics of stable and efficient data transmission,security of data transmission and so on.FTP Serverr occupies a large proportion in data storage Serverr.It is of great significance to study the implementation principle and performance optimization of FTP Serverr.With the continuous increase of network bandwidth,users often have GB level large files that need to be transmitted in the network.However,the traditional FTP Serverr has poor performance in the transmission of large files,and the transmission efficiency is very low.In order to realize the high efficiency and reliable transmission of the large files of the FTP protocol,the optimization is optimized.Large file transmission on FTP Serverr has important practical significance.The focus of this paper is to optimize the efficiency of FTP file Serverr in Linux environment.The designed FTP Serverr has the functions of basic file upload and download,user authentication and so on.The Linux operating system selected in the development process is Redhat system.The paper first introduces the theoretical basis of FTP protocol and the commonly used commands of FTP,including FTP working model,linking mode,working mode and data presentation mode.Then it introduces the construction of FTP Serverr function in Linux environment,including file upload and download function and user login check function.Then the paper studies the optimization of FTP uploading performance,and focuses on the optimization of the transmission performance of large files.Through the multi thread processing technology,the large files are uploaded and the split files are merged.Finally,the performance of the optimized FTP Serverr is tested,and the accuracy and efficiency of the data transmission in the process of file upload and download is tested respectively.After the FTP Serverr is realized by multi thread programming,the system has the function of high efficient upload,download and user checking of the file.At the same time,the FTP Serverr in this paper has more efficient data transmission efficiency in the large file transmission.
