netperf (www.netperf.org) probably will fit your needs if you wanted tcp/udp performance throughput. You can also use ttcp, iperf, or any number of other programs available. For that matter, you can set payload size and interval even using ping, if icmp packets suffice :) thanks, Nivedita --- Nivedita Singhvi (503) 578-4580 Linux Technology Center nivedita@us.ibm.com IBM Beaverton, OR nivedita@sequent.com > Hello, > I need to measure throughput between different nodes in > an IP network.
