  2. Daily results now online: http://corn.eos.nasa.gov/performance/Net_Health/CEOS_list.html Includes results from Norway, NASDA, and Thailand Connectivity continues to improve European networks upgraded connectivity to US: Geant, Surfnet Abilene and CA*Net3 providing International Transit: NY <--> Chicago AMPATH: Connected to Brazil and Argentina Australia: AARnet connected to Abilene (PNW) Testing Changes: Restarted testing to Israel, JRC, Russia (CAO), KNMI, EUMETSAT All UNEP hosts deactivated (Norway test source stopped in April) Looking for a replacement European host Testing from NASDA temporarily stopped 17 January '02 Hope to resume after reconfiguration New Performance Tool: Web100 Use with Iperf or others -- simplifies analysis Network Performance Testing Highlights

  23. CEOS Results Summary

  24. New Network Performance tool Useful for end-to-end performance analysis Available from http://www.web100.org Runs on a linux box -- Web100 kernel Allows Applications to access network metrics Runs with modified version of Iperf Reports network metrics for tests run Makes inferences about bottlenecks: Sender, network, or receiver Also has GUI for real time monitoring Or can use API to access metrics directly Web 100
