说明：  网络编程，原始套接字编程实验实验。具体功能如下： IP首部的构造；基于原始套接字的分片ICMP ECHO请求发送功能；基于原始套接字的ICMP ECHO响应接收功能；重叠分片的发送功能； 可以用来测试windows系统和Linux系统的重叠分片重组策略。 编程语言：C++
(Network programming, original socket programming experiment experiment. Specific functions are as follows: the structure of the IP header based the original socket slice ICMP ECHO request to send receive raw socket-based ICMP ECHO response functions the overlap slice send function can be used to test the windows system and Linux The systems overlap slicing restructuring strategy. Programming languages: C++)
