Network Performance Testing Highlights

Network Performance Testing Highlights

• 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
