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.
One other freeware/open-source tool you might want to look at is
pchar which attempts to characterize available bandwidth on each link.
intersting never heard of ;)

pchar sends probe packets into the network of varying sizes and
analyzes ICMP messages produced by intermediate routers, or by the
target host. By measuring the response time for packets of different
sizes, pchar can estimate the bandwidth and fixed round-trip delay
along the path. pchar varies the TTL of the outgoing packets to get
responses from different intermediate routers. It can use UDP or ICMP
packets as probes; either or both might be useful in different
situations.
