摘要
现有的FTP实现主要基于标准的流模式传输文件。本文首先分析表明,FTP流传输在连续传输多个文件时,由于重复地进行数据连接的建立、释放操作会导致传输效率低下。然后提出一种自动打包的文件传输模式,将多个文件传输转换为一个文件传输,以解决流模式效率偏低的问题,实验结果表明自动打包文件传输模式有效。
The existing FTP implementations are mainly based on standard stream mode to transfer files. Firstly,the analysis shows that when FTP stream transfers multiple files continuously,the transmission efficiency is low due to repeated data connection establishment and release operations. Then a file transmission mode of automatic packaging is proposed,which converts multiple file transmission into one file transmission in order to solve the problem of low efficiency of stream mode. The experimental results show that the file transmission mode of automatic packaging is effective.
