本设计的功能是填充一个TCP数据包，并发送给目的主机。 程序具体要求如下： 1) 以命令行形式运行：SendTCP、source_ip、source_port、dest_ip、dest_port，其中SendTCP是程序名，source_ip为源端IP地址，source_port为源端口号，dest_ip为目的地址，dest_port为目的端口号； 2) 其他的TCP头部参数请自行设定； 3) 数据字段为“This is my homework of network ,I am happy ！” 4) 成功发送后在屏幕上输出“Send OK” 。 -The design features are filled with a TCP packet, and send the purpose of the host. Program specific requirements are as follows: 1) to form the command line run: SendTCP, source_ip, source_port, dest_ip, dest_port, which are SendTCP program name, source_ip client IP address as the source, source_port as the source port number, dest_ip for the purpose of the address, dest_port for the purpose of port number 2) the head of other TCP parameters at your own settings 3) data fields for the This is my homework of network, I am happy! 4) successfully sent the output on the screen after the Send OK .

网络拓扑生成代码,是从http://www.cs.bu.edu/brite/download.html下载的，可以参考一下 brite c -network topology generated code from http :// www.cs.bu.edu/brite/download.html downloaded, can reference brite c

windows下的，一个网络嗅探器的源码，有一定的借鉴价值，可以构写自己的嗅探器了-under the windows, a network sniffer the source code for a certain reference value can write their own structure with a sniffer
