Subject: [smokeping-users] Traceroute probe


Hi everyone,

Has anyone ever tried to develop a traceroute probe that would display
time series for each hop?
It would permit to detect and localize link congestion or packet loss on
the path.
The main difficulty i see is about dealing with changing network paths.

For example, each periodic test would display 5 values for each hop and
the graph may look like 6 different lines. Therefore each test would
display 30 values.

# traceroute -f 4 -n -q 5 www.google.com
traceroute: Warning: www.l.google.com has multiple addresses; using
209.85.135.104
traceroute to www.l.google.com (209.85.135.104), 30 hops max, 40 byte
packets
