Pathping

Pathping是Windows系統中自帶的一個網路診斷工具，用於檢測本地至目的地之間節點的網路延遲和穩定性。原理.pathping在一段時間內，從本地至目的地之間傳送多個Echo Request訊息給中間經過的每個節點，然後基於資料包從每個路由器返回的資訊來計算結果。所以，pathping可以顯示每個節點的資料包丟失的百分比，以便判斷具體哪個節點或子網可能出現網路故障。pathping與tracert執行相同的路由跟蹤命令去識別這條路徑上有哪些路由器，但它額外多了一個步驟：給每個節點發送100個數據包，獲取返回資訊後去計算每個節點的統計資訊。範例.C:\Documents and Settings\User&gt;"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_nameOptions:-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.例子.&gt;"pathping wikipedia.org"Tracing route to wikipedia.com [207.142.131.235]over a maximum of 30 hops:0 simonslaptop [192.168.0.11]1 192.168.0.12 thus1-hg2.ilford.broadband.bt.net [217.32.64.73]3 217.32.64.344 217.32.64.1105 anchor-border-1-4-0-2-191.router.demon.net [212.240.162.126]6 anchor-core-2-g0-0-1.router.demon.net [194.70.98.29]7 ny1-border-1-a1-0-s2.router.demon.net [194.70.97.66]8 ge-8-0-153.ipcolo1.NewYork1.Level3.net [209.246.123.177]9 ae-0-51.bbr1.NewYork1.Level3.net [64.159.17.1]10 so-2-0-0.mp1.Tampa1.Level3.net [209.247.11.201]11 ge-6-0.hsa2.Tampa1.Level3.net [64.159.1.10]12 unknown.Level3.net [63.208.24.2]13Computing statistics for 325 seconds...Source to Here This Node/LinkHop RTT Lost/Sent = Pct Lost/Sent = Pct Address0 simonslaptop [192.168.0.11]0/ 100 = 0% |1 0ms 0/ 100 = 0% 0/ 100 = 0% 192.168.0.10/ 100 = 0% |2 18ms 1/ 100 = 1% 1/ 100 = 1% thus1-hg2.ilford.broadband.bt.net [217.32.64.73]0/ 100 = 0% |3 18ms 0/ 100 = 0% 0/ 100 = 0% 217.32.64.340/ 100 = 0% |4 21ms 0/ 100 = 0% 0/ 100 = 0% 217.32.64.1100/ 100 = 0% |5 21ms 1/ 100 = 1% 1/ 100 = 1% anchor-border-1-4-0-2-191.router.demon.net [212.240.162.126]0/ 100 = 0% |6 --- 100/ 100 =100% 100/ 100 =100% anchor-core-2-g0-0-1.router.demon.net [194.70.98.29]0/ 100 = 0% |7 --- 100/ 100 =100% 100/ 100 =100% ny1-border-1-a1-0-s2.router.demon.net [194.70.97.66]0/ 100 = 0% |8 100ms 0/ 100 = 0% 0/ 100 = 0% ge-8-0-153.ipcolo1.NewYork1.Level3.net [209.246.123.177]0/ 100 = 0% |9 94ms 0/ 100 = 0% 0/ 100 = 0% ae-0-51.bbr1.NewYork1.Level3.net [64.159.17.1]0/ 100 = 0% |10 134ms 1/ 100 = 1% 1/ 100 = 1% so-2-0-0.mp1.Tampa1.Level3.net [209.247.11.201]0/ 100 = 0% |11 137ms 0/ 100 = 0% 0/ 100 = 0% ge-6-0.hsa2.Tampa1.Level3.net [64.159.1.10]0/ 100 = 0% |12 131ms 0/ 100 = 0% 0/ 100 = 0% unknown.Level3.net [63.208.24.2]100/ 100 =100% |13 --- 100/ 100 =100% 0/ 100 = 0% win2000 [0.0.0.0]Trace complete.&gt;"pathping wikipedia.org -q 10"Tracing route to wikipedia.org [66.230.200.100]over a maximum of 30 hops:0 Aaron.hsd1.mn.comcast.net.
