I don't know if it helps, but anyways. There is another tool called Iperf (
http://sourceforge.net/projects/iperf ). It's usually used to report
bandwidth between two hops which you define, but it can be also used to
measure jitter, datagram loss, and a lot of other things, one in all it's
very handy if you want to get some idea regarding the network performance.

 Hi all, do you have any recommended tools that can measure latency/delay
hop by hop basis? Preferable the tools can measure the running (live)
traffic.


mtr ? - http://www.bitwizard.nl/mtr/


FWIW, Mtr measures latency/delay and loss based on ICMP messages heard back
from the routers on path.  As a result, in almost all cases, the real
hop-by-hop latency of actual end-to-end data packets is better than it can
report.
