Asked by Keith Pincombe on 2007-06-04

I've been doing traceroutes to various ip addresses for a while now and im just curious as to what asymm means in the results.

Normally you get a time such as 10ms or a star when the time is infinate but im not sure what asymm means

Thanks for the question.

asymm means the the path to the hop and back have been different (asymmetric). This usually happens when there is some link in one direction jammed or the network architecture encourages different paths for the different directions. The number after asymm shows the grade of asymmetry (i.e. how many hops are different).

I hope this helps.
