Network Performance Testing Highlights

Network Performance Testing Highlights

• Daily results now online:– http://corn.eos.nasa.gov/performance/Net_Health/CEOS_list.html

– Now includes results from Norway, NASDA, and Thailand

• Improved Peering– Many European networks upgraded connectivity to US

» NY, Chicago» Abilene and CA*Net3 providing International Transit

– AMPATH: South and Central Americas

• Testing Changes:– Israel: tested Nov-Dec ‘00– JRC: restarted Feb ‘01

– Thailand: Added UNInet
