局域网监控系统采用vc++6.0编写，需要oracle数据库(LAN monitoring system)

说明：  如何开发OPC Server.OPC主要适用于过程控制和制造自动化等应用领域。(this paper teach us how to make OPC Server.The main useful to use OPC is contoel.)

用于将网络边关系转换成matlab可用的临近矩阵。(Used to convert the network edge into matlab available close relationship matrix.)

AODV的源代码，包括c++、头文件以及编写用来测试的tcl(AODV source code, including c++, head files, and write to test of TCL )

求一段音频信号的短时过零率，可用于特征的选取，以及对音频进行分类筛选等场合。(For the sound process)

程序记录并显示了数据报从源端机器传送到目标机器的过程中所经过的路由器的IP地址，并且记录了数据报到达每个路由器所需要的时间。认真观察到达每个路由器的时间有什么区别，从而熟练掌握traceroute的工作原理和ICMP报文协议。　(The program records and displays the IP addresses of routers through which the datagram sent from the source client machine to the target machine , and the recording of the data packets arrive at the time required by each router . )

VC++源程序实现同步网络时间，基于C/S结构，启动服务端程序后，需要在客户端输入服务端的IP地址，然后点击“同步”按钮，如果顺利连接的话，则完成与服务器端的时间同步，注意，本程序并非是连接世界官方时间服务器，比如微软的时间同步服务器、NIST的服务器等，而是用本程序中的服务端来代替了。 (VC++ source code to synchronize network time, based on C/S structure, start the server program, you need the client enter the service side of the IP address, then click the " Sync" button, if successfully connected, then finished with the server time synchronization Note that this procedure is not an official time server connected world, the time synchronization server such as Microsoft, NIST' s servers, but with this program instead of the server.)

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)

编制程序，监控网络，捕获一段时间内网络上的IP数据包，按IP数据包的源地址统计出该源地址在该时间段内发出的IP包的个数，将其写入日志文件中或用图形表示出来（建议用图形表示出统计结果）。(Program monitoring network, a period of time to capture IP data packets on the network, according to the source address of the IP packet statistics of the number of the source address is issued in the time of the IP package, written into the log file or graph out (that show the statistical results with graphics).)

端口扫描器。 本扫描器实现了：TCP Connect 扫描，TCP SYN扫描，TCP Fin扫描，TCP ACK扫描及UDP端口扫描,这些扫描能够实现扫描特定IP地址范围内端口和扫描某IP地址范围内全部主机特定端口两种模式，并且SYN扫描能够区分端口开放、端口关闭和被防火墙过滤三种状态。(Port scanner. The scanner realized: TCP Connect Scan, TCP SYN Scan, TCP Fin Scan, TCP ACK scan and UDP port scan, the scan can scan a specific IP address range of ports and scanning a range of IP addresses all host two specific ports mode, and can distinguish SYN scan open ports, port closed and the three states firewall filters.)
