public class FilePacketMonitor
extends Object

 packet monitor, use to checkout reduplicated packet. not every packet needs reduplicated
 checkout, for example file data fragment packet, and so on.
 this monitor use policy as same as packetMonitor to clear buffer. toward reduplicated packet,
 it doesn't ignore, just some handle is no need. but even reduplicated, reply is need.
 包监视器，用于检测重复包。不是每个包都需要进行重复检测，比如文件数据分片的包等等。
 这个monitor采用和PacketMonitor一样的策略清空缓冲区。对于重复的包，并非不理睬，
 只是有些处理就不需要了，但是即使是重复包，回复也是需要的
