记录IP/TCP/UDP/ICMP网络包日志 -Recording ip/tcp/udp/icmp network logs

判断对方（设备，进程或其它网元）是否正常动行，一般采用定时发送简单的通讯包，如果在指定时间段内未收到对方响应，则判断对方已经当掉。用于检测TCP的异常断开。基本原因是服务器端不能有效的判断客户端是否在线也就是说，服务器无法区分客户端是长时间在空闲，还是已经掉线的情况。所谓的心跳包就是客户端定时发送简单的信息给服务器端告诉它我还在而已。代码就是每隔几分钟发送一个固定信息给服务端，服务端收到后回复一个固定信息。如果服务端几分钟内没有收到客户端信息则视客户端断开。比如有些通信软件长时间不使用，要想知道它的状态是在线还是离线就需要心跳包，定时发包收包。
