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 4 64.233.175.234 1.894 ms 1.827 ms 1.620 ms 1.717 ms 1.720 ms 5 72.14.232.104 18.466 ms 72.14.233.105 29.250 ms 29.406 ms 72.14.232.104 18.667 ms 18.511 ms 6 72.14.238.128 25.928 ms 25.905 ms 72.14.233.106 25.944 ms 26.012 ms 209.85.248.248 27.828 ms 7 72.14.239.46 28.041 ms 72.14.239.48 28.442 ms 28.388 ms 72.14.239.46 28.019 ms 27.952 ms 8 209.85.253.26 29.345 ms 72.14.239.54 41.336 ms 209.85.253.26 29.372 ms 72.14.239.54 29.306 ms 209.85.253.26 39.806 ms 9 209.85.135.104 28.256 ms 28.417 ms 28.313 ms 28.316 ms 28.177 ms cheers, Alexis
