Net all the way. – From NASDA: steady 350 kbps Andy Germain CEOS-WGISS-NS-11 Darmstadt, DE Septrember 2001 Page 6

Japan - NASDA • EOC - Hatoyama: – NASA-NASDA removed private E 1 and Japan - NASDA • EOC - Hatoyama: – NASA-NASDA removed private E 1 and installed private 3 mbps ATM service in Feb '00 -- for mission support only. » Performance stable - typically 1. 6 mbps – Route via STAR TAP (Chicago) / Trans. PAC / IMnet for US Science data » Performance stable - typically 1. 2 Mbps – New testing from GISTDA: via APAN /Imnet -- also 1. 2 mbps – New testing from AIT; via Sinet / Imnet - 700 kbps typ. • NASDA testing to several CEOS sites is available on the Web site Andy Germain CEOS-WGISS-NS-11 Darmstadt, DE Septrember 2001 Page 7

Teleglobe), Nordunet, UNInet » Performance from GSFC improved December '00 • Was 25 -115 kbps, now 650 -2900 kbps! – Geneva: from GSFC as of 30 -Jun-01 to UNEP Norway, then via satellite » was via Abilene (prev BBNplanet), Swisscom, IPplus » Performance from GSFC only 50 -115 kbps -- Was 700 -1300 kbps! • Improved in April '01, was 28 -400 kbps before that » From Norway: Now single UNEP satellite hop! Also 50 -115 kbps – via satellite from Norway » Beijing: Performance improved 10 -March-01 • From GSFC: Was 12 -110 kbps, now 17 -165 » Nairobi: testing stopped 9 '00 -- performance was 75 -500 kbps » Bangkok (was via Geneva) • From GSFC improved to 50 -110 in May '01, was 15 -110 kbps Apr '01 -- was 15 -55 prev. • Very similar results from Norway » Costa Rica: decreased to 40 -100 kbps 30 -June-01 • was 50 -160 kbps Mar '01, and 23 -110 kbps since Oct '99 Andy Germain CEOS-WGISS-NS-11 Darmstadt, DE Septrember 2001 Page 10

Inactive Sites • China: START Regional Center -- Still down – – No performance Inactive Sites • China: START Regional Center -- Still down – – No performance testing since Aug '99 (was 18 kbps) New route from SFO via "Concert" -- terrestrial Old route via AT&T, satellite -- appeared highly congested APAN would be better • Germany: – DLR (Oberpfaffenhofen): » Test host unresponsive since July '99 » Route via Abilene (was UUnet) to NY, DFN – Eumetsat » Performance testing still not running -- gave up! » Route via KPNQwest to Darmstadt • Israel: Last tested Nov-Dec '00: – Performance 0. 2 - 1. 7 mbps (was 1. 7 mbps steady) – Route via Abilene peering with ILAN in Chicago – Datasink stopped in Dec 00 -- POC gone -- will try to restart.

Inactive Sites (cont. ) • Malaysia (UKM): Testing stopped June '00 – Thruput tested Inactive Sites (cont. ) • Malaysia (UKM): Testing stopped June '00 – Thruput tested 19 -20 Jan '00: 30 kbps – Route via ATT. net, "Concert" terrestrial link (was satellite) • Netherlands (KNMI): tested Sept - Nov '00 – Route from GSFC via Abilene to Surf. Net in NY – Performance 0. 9 -1. 8 mbps to KNMI, 10 -18 mbps to Surf. Net core – Upgrades planned soon -- will resume testing • Russia (IRE-RAS - Moscow): Testing Oct - Dec ‘ 00 – Route is via Internet -- Rostelecom in NY – Better alternatives: MIRnet, or NASA dedicated circuit – Performance was BHM = 75 kbps, Daily range = 13 - 30 kbps • Russia (CAO - Moscow): SAGE III Project – Route via NY to Rostelecom/RBnet -- Severe Congestion! » Still trying to use NASA dedicated circuit – Performance typically 2 -76 kbps; median 18 kbps Andy Germain CEOS-WGISS-NS-11 Darmstadt, DE Septrember 2001 Page 12
