Summary • • • Free. BSD 4. 7 didn’t work well with some Gb. E cards. Linux 2. 4 works well. Iperf 1. 6. 5 is not well coded. (I needed to modify) Scripts to find the best parameters (automated). Every 10 seconds SNMP polling (too fast? ) Long term rrdtool records (from IU) ATM performance test by APAN Tokyo XP Next steps: IPv 6, Multicast Other measurements: IPv 4 / v 6 ping, hops, routes • Available at http: //mrtg. qgpop. net
