FTP (file transfer protocol) file transfer method based on asynchronous read-write and FTP client

Abstract

The invention discloses an FTP (file transfer protocol) file transfer method based on asynchronous read-write and an FTP client and relates to the field of FTP configuration. The method comprises the following steps: the FTP client acquires FTP file sizes locally according to FTP file information needing to be read or written; FTP files are split into a plurality of read-write data blocks according to the file sizes; the FTP client sends an asynchronous file read-write request message to a message drive framework, and the message drive framework acquires a read-write worker thread in a preset thread pool; data blocks needing to be read or written in the FTP files are read by means of the read-write worker thread according to the asynchronous file read-write request message. According to the method, basic functions of FTP cannot be affected while high efficiency of the message drive framework is guaranteed, FTP is brought into the message drive type software framework perfectly, and the method is quite suitable for being popularized.

Description

technical field [0001] The invention relates to the field of FTP configuration, in particular to an FTP file transmission method based on asynchronous reading and writing and an FTP client. Background technique [0002] In the current data communication transmission equipment, in order to improve the modularization and operation efficiency of the software, the core software generally adopts the message-driven software framework. In order to realize the basic network management function, FTP (File Transfer Protocol, file transfer protocol) is generally required as a most basic software feature. However, when FTP is incorporated into a message-driven software framework, there is a problem: FTP is a file-intensive protocol for reading and writing. Due to the inefficient and time-consuming IO (input and output) operations of FTP files (because FTP files are large, generally is about 100M), so after incorporating FTP into the message-driven framework, transferring the entire lar...

Problems solved by technology

However, when FTP is incorporated into a message-driven software framework, there is a problem: FTP is a file-intensive protocol for reading and writing. Due to the inefficient and time-consuming IO (input and output) operations of FTP files (because FTP files are large, generally is about 100M), so after incorporating FTP into the message-driven framework, transferring the entire large FTP file will reduce the efficiency of the overall scheduling of the framework, and even cause other program components to be difficult to work normally

[0003] For a long time, the contradiction between the inefficiency of file operations and the overall efficiency of the platform has been a difficult problem to solve

Based on this point and in order to avoid the above problems, most of the current software platforms give up the asynchronous implementation of FTP, and place the implementation of FTP outside the message-driven framework, which will inevitably cause damage to the integrity of the software platform and make it more complicated. The communication mechanism of the software will make the usability of the software worse and worse
