| Help understanding traceroute output
Hello,
I have a question regarding traceroute and hope you can help (I really could not find the answer online). Supposse a typical traceroute is issued as follows (removed some unnecesary output and replaced it with "...":
Tracing route to news-east.usenetserver.com [63.211.125.90]
over a maximum of 30 hops:
1 3 ms 3 ms 2 ms my.router [xxx.xxx.xx.xxx]
2 35 ms 36 ms 35 ms rbtserv5.exit109.com ...
...
5 42 ms 44 ms 52 ms 113.ATM ...[146.188.176.34]
6 43 ms 41 ms 41 ms ...[152.63.17.218]
7 61 ms 41 ms 41 ms 181.ATM6...[152.63.22.225]
8 41 ms 42 ms 47 ms 137.39.52.10
9 47 ms 42 ms 42 ms so-6-0... [209.247.10.45]
...
11 104 ms 68 ms 80 ms .. [63.211.125.90]
Trace complete.
Why is that hop #8 shows less milliseconds than hop #7? Can you explain to me the time of the second column? Is it the time it takes from the source to that particular location and back? I thought that a package will go from one hop, to the other, and so I thought that as a consequence the time should increase each time a hop is reached.
THANKS!
