一个完善的升级程序，可供编写自动升级程序模块参考。(A complete update program solution.)

通信网络的架设问题 若要在n（≥10）个城市之间建设通信网络，只需要架设n-1条线路即可(With the Dijksra algorithm to network G from source points to the rest of the vertices of the shortest path)

聊天室源码，支持多人聊天，服务器端(Chat room source code, support for multiplayer chat, chat room source code, support for multiplayer chat,)

基于HTTP协议的支持断点续传的下载软件源码(HTTP protocol support for HTTP-based download software source)

网络重传选择协议，可以检查传输信息的正确性。通过接受方的校检，通知发送方重新发送。 ( Network retransmission protocol, you can check the correctness of the transmission of information. By accepting the prosecution s school to notify the sender to resend.)

获得IP地址和MAC地址的对应关系网络课实验。 根据IP地址发送和接受ARP包获得对应MAC地址。(Access to correspondence between the experimental class network IP address and MAC address. Send and receive ARP packets to obtain the corresponding MAC addresses based on IP addresses.)

说明：  局域网视频会议，vc6.0/Windows XP编译通过。(LAN video conferencing, vc6.0/Windows XP compile.)

说明：  DNS解析系统，通过发送DNS协议包到DNS服务器来获取DNS(DNS analysis system, the agreement by sending a DNS packet to the DNS server to obtain the DNS)

低电阻测试仪上位机程序，带参数设置功能自动量程、讯响、单次连续、报警上下限设置，及测量数据即时上传功能(Low resistance tester upper computer program, with parameter setting function, automatic range, sound, single continuous, alarm upper and lower settings, and measurement data immediate upload function)

它是一个c/s网络编程框架，基于对boost.asio的包装（最低在boost-1.49.0上调试过），目的是快速的构建一个c/s系统；效率高、跨平台、完全异步，当然这是从boost.asio继承而来； 自动重连，数据透明传输，自动解决分包粘包问题（这一特性表现得与udp一样）； 只支持tcp和udp协议；(It is a c/s network programming framework, based on boost.asio package (minimum tried to increase the boost-1.49.0), the purpose is to build a fast c/s systems efficient, cross-platform, fully asynchronous, Of course, this is from boost.asio inherited Auto-reconnect, transparent data transmission, automatic sub-stick package to solve the problem (this feature behave the same with udp) Only supports tcp and udp protocol )
