given that the latency to hop 9 is basically the same as hop14 you're looking at mpls... if the transpacific hop were on top of that you'd see at least another 100 ms added to the rtt between 9 and 11. it's 9655 miles IAD - SIN over the pole, realistically an actually fiber paths is likely more than 12000 so you'd expect to see ~more than 150ms rtt under the best circumstances... > Can someone please enlighten me as to if I am correct or not? > > Tracing route to 128.199.162.241 over a maximum of 30 hops > > 1 <1 ms <1 ms <1 ms 192.168.1.254 > 2 1 ms <1 ms <1 ms > 23-25-112-190-static.hfc.comcastbusiness.net [23.25.xxx.xxx] > 3 27 ms 22 ms 19 ms 96.178.10.1 > 4 10 ms 9 ms 10 ms > te-1-3-ur01.shadygrove.va.richmond.comcast.net [68.86.124.241] > 5 17 ms 17 ms 17 ms > xe-12-0-1-0-ar02.charlvilleco.va.richmond.comcast.net [68.86.172.17] > 6 24 ms 24 ms 25 ms > pos-1-2-0-0-cr01.ashburn.va.ibone.comcast.net [68.86.91.53] > 7 24 ms 23 ms 23 ms > pos-0-3-0-0-pe01.ashburn.va.ibone.comcast.net [68.86.86.142] > 8 20 ms 20 ms 20 ms 66.208.233.38 > 9 268 ms 264 ms 265 ms if-6-8.tcore2.lvw-los-angeles.as6453.net > [216.6.87.114] > 10 * * * Request timed out. > 11 270 ms 255 ms 256 ms if-2-2.tcore1.svw-singapore.as6453.net > [180.87.12.1] > 12 270 ms 271 ms 275 ms if-11-2.thar1.svq-singapore.as6453.net > [180.87.98.37] > 13 260 ms 258 ms 260 ms 180.87.98.6 > 14 256 ms 256 ms 258 ms 103.253.144.242 > 15 262 ms 258 ms 259 ms 128.199.162.241 > > Trace complete.? >
