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.
