这是一个测试UDP数据包的丢包率的程序，包含程序源码，已经验证成功(This is a test UDP packet loss rate of the program, including program source code, has been successfully verified)

VB开发的IP测试程序，这是在我工作中写的调试程序，在配置文件中只需要写上相应的IP，程序就会循环测试IP地址是否在线，不在线的话就会报警提醒(VB development of IP test program, which is written in my work debugger, just write in the configuration file on the corresponding IP, the program will loop test IP address is online, not online, then it will alarm to remind)

利用wincap直接与网卡通讯发送数据，千兆网卡效率达到100 ，全速！！！完全自定义数据包协议传输，数据每秒钟100M字节有木有！(wincap high speed data 100 MBytes/s=1000Mbits/s)
