摘要
NC(网络计算机 )是伴随互联网发展而产生的终端新概念 ,具有信息安全性好、易管理、成本低等显著优势。为了便于各种应用平台在NC环境中的移植 ,透彻分析其中基本通信过程则显得更为重要。本文简单介绍了NC基本概念和工作原理 ,并重点分析了运用NC环境所使用的基于TCP连接的特定通信协议。微软公司开发的远程桌面协议RDP(RemoteDesktopProtocol)就是基于NC环境应用而推出的尚未开放的商业保密通信协议。笔者参考了开放源码的rdesktop客户端软件 ,对RDP协议从基本概念、工作原理、运行流程、数据结构进行了全面的分析。
NC--NetworkComputer is a new conception of terminal,going with the effective development of Internet,having many prominent advantages such as good information security,easy management and low cost.In order to transplant from different platforms to NC environment,it is (necessary) for us to analyze the communication process in detail.This paper introduces the basic conception and the operation principles of NC at first.Then,it emphasizes to analyze the special TCP-connection-based communication protocol in NC environment.Furthermore,the RDP(Remote Desktop Protocol) explored by the Microsoft corporation is introduced,which is based on NC environment,but unopened source as a business secret.Finally,referring to the open source code client software -- rdesktop,the authors analyze the RDP at length from all the aspects including basic conception,operation principle,and data structure etc.
