文件传输协议(file transfer protocol,FTP)是网络传输文件的常用协议,内容较复杂.由于采用了传输控制协议(transport control protocol,TCP)提供的可靠传输服务,使用FTP传输文件时经常出现数据延迟问题.为此提出一种文件获取协议(file obtain protocol,FOP).FOP底层传输使用用户数据报协议(user datagram protocol,UDP),无需非常复杂的传输模型即可实现在网络上传输包括音视频在内的多类型文件.同时介绍了FOP的工作原理和实现方法,编写了基于FOP协议的客户和服务器软件.

The File Transfer Protocol is a common protocol for file transfer in network, but the contents of FTP is complicated. FTP has often data transmission delay problem when transferring files, this is due to FTP uses the service provided by Transport Control Protocol. Therefore this paper presents a File Obtain Protocol. FOP uses User Datagram Protocol as the underlying transport protocol, FOP can transfer multiple types of files without complicated transmission model, these files include audio, video and so on. This paper introduces the working principle and realization method of the FOP,and the client software and server software based on FOP.
