基于Socket的网络编程技术及其实现学士学位论文【理工大学】.docVIP

摘 要 随着网络技术的飞速发展，计算机给人类文明带来了翻天覆地的变化，原来物理上的接口已不能满足网络通信的要求了。TCP/IPTransmission Control Protocol/Internet Protocol）协议作为网络通信的基本协议就解决了这一通信难题，引入了一种称之为Socket”的应用程序接口。Socket 是建立在传输层协议上的一种套接字规范，基于Socket的网络编程已是一项现如今被广泛利用的技术，很大程度上方便了人们的生活。 本文以VC++6.0为开发环境，套接字的网络编程，修改系统配置文件 本文远程系统的关键技术，系统的需求分析。设计了系统的基本框架和各个模块的功能主要模块具体实现。 关键字：Socket；VC++；；远程控制  With the rapid development of network technology, computer has brought human civilization aundergone enormous changes, the original physical interface has been unable to meet the requirements of network communication. As the network communication protocol TCP / IP protocol solved the basic problem of this communication, the introduction of a technique called Socket application program interface. Socket network based on programming is a widely utilized nowadays . In this paper, VC 6.0 development environment, socket-based network programming, implementation and process control system that allows the local computer through the LAN to access different remote computers, and its operation can also be carried out Internet host. This article first briefly introduces the remote desktop monitoring system key technologies, as well as system requirements analysis. The basic framework of the system design and function of each module; then introduces the various functional modules of the specific implementation steps. Finally, test methods and results, the advantages and disadvantages of the system are summarized. Keywords：Socket；VC++；Network Programming；Remote Control 目录 1 绪论 1 1.1 课题的背景和意义 1 1.2 课题的国内外研究现状 1 1.3 课题的结构安排 2 2 Socket网络编程的关键技术 3 2.1 Socket网络编程理论基础 3 2.1.1 OSI七层网络模型与TCP/IP四层网络模型 3 2.1.2 Socket编程基本原理 6 2.2 Windows Socket网络编程技术 10 2.2.1 Winsock简介 10 2.2.2 Winsock通信机制 10 2.2.3 Winsock编程模型 11 2.3 图像技术 13 2.4 图像压缩编码解码 16 2.4.1 霍夫曼压缩 17 2.4.2 Run Length压缩 17 3 远程控制系统总体设计 19 3.1 系统需求分析 19 3.1.1 用户需求 19 3.1.2 可采用的技术方案 19 3.2 可行性技术方案 19 3.2.1 技术可行性 19 3.2.2 经济可行性 20 3.3 系统的基本框架 20 3.4 模块划分及功能设计 21 4 系统的详细设计与实现 22
