文档介绍：基于java的远程登录和文件传输功能的实现
(计算机科学与技术学院 2000级4班)
摘要
发展至今产生了两种比较重要的网络体系结构:ISO/OSI和TCP/IP参考模型,ISO/OSI模型有7层:物理层,数据链路层,网络层,传输层,会话层,表示层,应用层。而TCP/IP模型只有4层:主机至网络层,互连网层,传输层,应用层。其中TCP/IP参考模型中的应用层包含所有的高层协议,最早引入的是虚拟终端协议,文件传输协议和电子邮件协议。本文对网络计算机相互通信的机理进行比较细致和深入的分析,并采用java编程工具实现了远程登录和文件传输的功能。

Abstract
produces two kinds of more work system structure so far that is developed, ISO/OSI and TCP/IP consult models, ISO/OSI model is 7 layers: Physics layer, data link layer, network layer, transport layer, session layer, persentaltion layer, opplication layer. And TCP/IP model is 4 layers: From puter to , network layer, transport layer, opplication layer. TCP/IP among them consult application layer of model include all on the senior level Protocol, introduce work , File Transfer Protocol and Simple Mail Transfer Protocol, Careful and deep analysis that this pares mechanism that municates each other, and adopt java programming tool to realize the functions of work and file transfer.
KEY WORDS: TCP/IP JAVA FTP
