局域网文件传输的设计与实现
摘要
随着互联网技术的迅猛发展,计算机通信给人类文明带来了翻天覆地的变化。很多情况下,人们的日常工作需要借助文件传输来完成。上的服务器才能实现。这就给那些具有大规模内部网络的用户造成了许多问题,如浪费资金、浪费网络资源、病毒入侵、降低了工作效率等。为了方便局域网内主机的资源共享,需要开发一个基于局域网的文件传输工具,在内部网络中实现文件交换。
基于局域网的文件传输系统的设计选用Virtual Studio 2008 为开发工具,以C/S模式通过建立Socket连接后实现局域网快速,准确,安全的点对点文件以及文件夹传输功能。本系统能够促进局域网内用户之间的文件资源共享,满足主机之间信息交流,确保文件及文件夹传输安全性,有效地提高工作效率。
设计共分为五大模块,分别为:一、介绍选题背景及意义和国内外研究现状;二、介绍TCP/IP点对点协议技术,C/S架构的MFC程序设计技术和Socket网络编程技术;三、对当前局域网文件传输进行需求分析并提出解决方案;四、根据解决方案对系统进行设计;五、对基于局域网的文件传输系统进行测试并得到测试结果。

LAN Design and Implementation of File Transfer
Abstract
With the rapid development of technology, munications to the human civilization has brought tremendous changes. In many cases, people's daily work to be done with the file transfer. However, most file transfer needs with a removable disk and other hardware devices or servers on the can be achieved. This work to those users with large-scale caused many problems, such as a waste of money, a waste work resources, virus attacks, reduced work efficiency. In order to facilitate resource sharing on machines within the LAN, you need to develop a LAN-based file transfer tool, in the work for file exchange.
LAN-based file transfer system designed for the selection of Virtual Studio 2008 development tools to C / S mode to achieve through the establishment of local work Socket connection fast, accurate and secure files and folders point to point transmission. The system can promote the local work file sharing between users, to meet the information exchange between the host, transfer files and folders to ensure safety, effectively improve the work efficiency.
Design is divided into five modules, namely: I, introduce the research background and significance and research status; II introduces TCP / IP point to point protocol technology, C / S architecture MFC Socket programming techniques work programming ; III LAN file transfer on
