基于opnet的胖树多播网络仿真，主要为多播算法的仿真，程序较完善(Opnet fat tree multicast network simulation, primarily for multicast algorithm based simulation program better)

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)

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)

说明：  输入参数：某个web地址，端口号（默认80）。 连接成功后，提示，输入：某个文件名。例如index.jsp 获取文件成功后，输出发送的字节数和接收到的字节数。关闭(Input parameters: a web address, port number (default 80). Connection is successful, prompt, type: a file name. For example, access to the file index.jsp is successful, the output number of bytes sent and received bytes. Close)
