A公司局域网文件传输存在的问题及对策
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Delphi 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Delphi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。

The Design and Implementation of File Transfer System Based on LAN
Abstract
Along with the technology swift and violent development, puter correspondence the human culture has brought the earth-shaking change for. In very many situations, people's routine work needs to draw support from the file transfer plete. But the majority file transfer function all needs to draw support moves hardware equipment or the and so in the floppy disk server can realize This gave these to have the large-scale work user to create many problems, like the waste fund, the work resources, the viral invasion, reduced the working efficiency and so on. In order to facilitate in the local work main engine resources sharing, needs to develop one based on the local work file transfer tool, realizes the document exchange in work.
The design and implementation of file transfer system base on LAN uses Delphi development tool,C/S mode through the establishment of Socket after connecting LAN users fast, accurate, the point-to-point security files and folders transmission functions. The system can contribute to LAN users to share file resources to meet the exchange of information between mainframe, ensure that the filets and folders transmission security, effectively improving efficiency.
The design is divided into five major module altogether, including: First, introduction selected topic background and significance and domestic and foreign research present situation; Second, introdu
