RC4算法的加密实现，实现对明文的加密，加密效果很不错(RC4 encryption algorithm, has implemented an express right of encryption, encryption is very good effect)

C语言实现的监听网络流量的程序，并对截取的报文进行分析。(C language to monitor the flow of network procedures, and analysis of the interception of the message.)

说明：  该源码主要描述了计算机进行数据实时数据传输时所使用的RTP协议，介绍了该协议的基于C++的API函数，及基本的实现过程，有利用实现网络编程。(The main source of data describing the computer real-time data transmission protocol used by RTP, described the agreement based on C++, API functions, and basic implementation process, there is use for network programming.)

Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.

说明：  这是非常好的关于网络编程的例子，实现了ping程序，对于学习网络编程的人员来说是非常难得的材料。(It is a very good example of programming on the network to achieve the ping process, for learning network programming staff is very rare material.)

这个是关于网络工作室的源代码,主要是用于网络编程的初级参考,希望能给刚入网络编程的朋友提供帮助(This is a studio on the network)

socket通信tcp实现的聊天室程序源码(tcp socket communication program source code to achieve the chat room)

说明：  代理服务器，还不完善，总丢数据，个人没有能力改了，有需要的朋友参考一下吧(Proxy server, not perfect, the total lost data, individuals can not afford to change, and a friend in need reference it)

说明：  网络文件系统，十分好的文件传输代码，非常适合初学者(Network file system, file transfer is very good code, very suitable for beginners)

通过客户端与服务器端文件对比，实现自动升级功能。(Through the client and server-side document comparison, automatic update feature.)
