Pathping

thumb

Pathping是Windows系统中自带的一个网络诊断工具，用于检测本地至目的地之间节点的网络延迟和穩定性。
原理
pathping在一段时间内，从本地至目的地之间发送多个Echo Request消息给中间经过的每个节点，然后基于数据包从每个路由器返回的信息来计算结果。所以，pathping可以显示每个节点的数据包丢失的百分比，以便判断具体哪个节点或子网可能出现网络故障。pathping与tracert执行相同的路由跟踪命令去识别这条路径上有哪些路由器，但它额外多了一个步骤：给每个节点发送100个数据包，获取返回信息后去计算每个节点的统计信息。
范例
 C:\Documents and Settings\User>pathping
 Usage: pathping [-g host-list] [-h maximum_hops] [-i address] [-n]
 [-p period] [-q num_queries] [-w timeout] [-P] [-R] [-T]
 [-4] [-6] target_name
 Options:
 -g host-list Loose source route along host-list.
 -h maximum_hops Maximum number of hops to search for target.
 -i address Use the specified source address.
 -n Do not resolve addresses to hostnames.
 -p period Wait period milliseconds between pings.
 -q num_queries Number of queries per hop.
 -w timeout Wait timeout milliseconds for each reply.
 -P Test for RSVP PATH connectivity.
 -R Test if each hop is RSVP aware.
 -T Test connectivity to each hop with Layer-2 priority tags.
 -4 Force using IPv4.
 -6 Force using IPv6. C:\Documents and Settings\User>ver
