And how exactly would you interpret the number returned by net_loss (int), in a column called "LOSS", in reference to reachability of a "hop" between two end points: int net_loss(int at) { if ((host[at].xmit - host[at].transit) == 0) return 0; /* times extra 1000 */ return 1000*(100 - (100.0 * host[at].returned / (host[at].xmit - host[at].transit)) ); } ?

Anybody having any idea why such a high packet loss on lever3's network, in Chicago?
End-user misinterpreting output from MTR. This network does not appear to have any packet loss end-to-end.
