IPv6环境下FTP系统的设计与实现

 

摘  要：IPv4是目前广泛使用的互联网IP技术，IPv6则是下一代的IP协议，注入了许多新的内容。随着互联网技术的不断发展，IP协议将慢慢从IPv4过渡到IPv6。文件传输协议是互联网上广泛使用的在远程计算机系统和本地计算机系统之间传输文件的标准。因此，本次毕业设计研究在IPv6环境下FTP系统的设计与实现。

    本设计首先阐述了IPv6的发展状况，然后介绍了IPv6协议在各流行操作系统下的安装与配置，最后按照RFC959－《标准文件传输协议》和RFC2428－《FTP对IPv6和NAT的扩展》的要求，采用支持IPv6 Socket编程的JDK5.0，实现了绝大部分的FTP传输命令，包括一个服务端与一个客户端程序，经测试，均可工作于IPv4与IPv6环境。

Abstract: While IPv4 is widely used technique at present in the internet, IPv6 is the next generation Internet Protocol that brings many new contents. Along with the development of internet technique, transition from IPv4 to IPv6 is necessary though maybe slowly. File Transfer Protocol is widely used in internet and is the standard of transfer file between remote computer system and local computer system. Consequently, I investigate the design and implement of ftp system in IPv6 environment.

  This paper first expounds the development of IPv6,then introduces IPv6's installation and configuration on popular operation systems, finally according to RFC595-<FILE TRANSFER PROTOCOL> and RFC2428-<FTP Extensions for IPv6 and NATs>,with JDK5.0 which supports IPv6 socket programming, implements a majority of FTP commands. This design presents a server site and a client site, which can work on IPv4 and IPv6 environment.
