Traceroute
Traceroute is designed for quick network route discovery. Unlike normal
traceroute, it traces all the way to host at once and saves tenth to
hundreds times. It also measures the time necessary for
packet to return and looks up all intermediate routers. Unlike normal
tracert it's based on UDP protocol, and allows to trace
networks where incoming ICMP messages are filtered.
The way it traces the route makes time measurement to be inadequate,
but it can be used as relative values. Assume first hop to be
<10 and subtract the difference from other hops. Please note
that far hop may take less time than near - it can be also seen in ICMP
traceroute, used by Windows. It's really so - it's a time, lost for
internal router processes before it answers.
Interface details:
Tries: maximum retry number if router was not discovered. Traceroute
will trace the route again until exceeds this value.
Hops: maximum number of hops to trace. This is assumed route length.
Usually do not exceed 30 hops and can't be more than 255. Be careful
with the hop number - too large number will flood the target host.
Time (milliseconds): maximum time to wait for router's answer. Timeout
assumes that the packet was lost.
Button "Host >" copies the clipboard contents to the question
line.
Operation description:
When started, traceroute attempts to trace all the way at once. Usually
it takes about 2 seconds to do it. If some of the routers were not
discovered it waits until timeout and re-asks the route. Upon
completion it narrows the results to the route length and looks up all
the intermediate routers.
