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. http://www.kitchenlab.org/www/bmah/Software/pchar/README -- thanks !!! -- Marc Manthey 50672 Köln - Germany Hildeboldplatz 1a Tel.:0049-221-3558032 Mobil:0049-1577-3329231 mail: marc@let.de PGP/GnuPG: 0x1ac02f3296b12b4d jabber :marc@kgraff.net IRC: #opencu freenode.net twitter: http://twitter.com/macbroadcast web: http://www.let.de Opinions expressed may not even be mine by the time you read them, and certainly don't reflect those of any other entity (legal or otherwise).
