Network Performance Testing Highlights

• Daily results now online
• http//corn.eos.nasa.gov/performance/Net_Health/CE
  OS_list.html
• Includes results from Norway, NASDA, and Thailand
• Connectivity continues to improve
• European networks upgraded connectivity to US
  Geant, Surfnet
• Abilene and CANet3 providing International
  Transit NY lt--gt 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

Web 100

• New Network Performance tool
• 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
