摘　　要：介绍了几种常用探测主机状态和分组时延的方法。SYN探测借鉴了TCP端口扫描原理,通过发送SYN包来测试主机、TCP端口状态;利用TCP包的发送序号与确认序号嵌入时间戳,计算分组时延。最后采用Windows网络编程和多线程技术实现了SYN探测方法。The thesis introduces several ways to probe the state of host and to get packet round trip time. SYN-probe detects the states of host and port by sending SYN packet like port scanning model. It employs two TCP packet＇ s fields, sequence number field and acknowledgement number field, to embed time stamps which are used to calculate packet round trip time. At last, SYN-probe is programmed by Windows network programming and multithread technologies.
