Network Performance Testing Highlights • Many new routes -- International High performance networks peer in the US in NY, Chicago • New tests: – – – CONAE (resumed 4 -00) Malaysia (19 -20 Jan 2000) Sea. Start (Bangkok) (9 -99) Tokai Univ (9 -99) UNEP: Added Geneva, Norway, Beijing, Bangkok, Costa Rica • Testing Stopped – – CSIRO (2 -99) DLR (7 -99) INPE (8 -98) START (China) (8 -99) Andy Germain CEOS-WGISS-NS-8 London, England April 2000 Page 2

Site Updates • CCRS (Canada): Stable – Routed stable -- direct peering between NISN and CA*Net 3 in Chicago -- to CCRS via a 5 mbps access circuit. – Business Hours Median (BHM) 3. 3 Mbps • China: START Regional Center – No performance testing since 8/99 – BHM performance was 18 Kbps – Route now via AT&T, satellite -- APAN would be better • CONAE (Argentina): Testing resumed 4 -00 – Thruput about 200 kbps via Telintar – Was 20 kbps when last tested (‘ 96) • CSIRO (Australia): – no thruput testing since 2/99 Andy Germain CEOS-WGISS-NS-8 London, England April 2000 Page 6

Site Updates • DLR (Oberpfaffenhofen, DE): – Route now via NY, TEN-155 to DFN – Datasink stopped 7/99 -- will try to restart • ESRIN (Frascati, IT): – – – BHM dropped to 60 kbps (was 80 kbps) typical range (BH) = 25 -1600 kbps (was 30 -650 kbps) Routing: ALTERNET - Dante (TEN-155) GARRnet (Milan)-ESRIN seems fairly stable -- fairly congested NASA switch to Abilene might help somewhat • Eumetsat (Darmstadt, DE): – Performance testing still not running -- will try again – Now (as of 18 Jan 2000) using EU-Xlink via Qwest » was NASA-ESOC dedicated circuit » Hops 7 ->13, RTT 210 -> 110, Loss 3% -> 10% Andy Germain CEOS-WGISS-NS-8 London, England April 2000 Page 9

Site Updates (cont. ) • INPE (Sao Paolo, BR) : No testing since 8/98 – Being reconfigured • IRE-RAS (Moscow, RU): – – Via Internet -- Teleglobe, Relarn MIRnet is another possibility Sink down since 2/24 Small performance improvement 1 Jan 2000: » BHM = 14 kbps, Daily range = 3 - 260 kbps » Was BHM = 8 kbps, Daily range = 2 - 200 kbps • Israel: Further improved performance – Route change 16 March 2000: NASA peers with ILAN in Chicago – Performance now 1. 7 mbps -- but somewhat unstable – Was about 100 kbps previously Andy Germain CEOS-WGISS-NS-8 London, England April 2000 Page 12

Site Updates (cont. ) • CEO/JRC (Ispra, IT) – BH Median about 140 Kbps; average daily peak is about 1700 Kbps – Route: SWITCH (NY) to JRC » Alter. Net from GSFC via MAE-E, Abilene from JPL – Fairly high congestion on both routes -- probably trans-Atlantic • Malaysia – Thruput tested 19 -20 Jan 2000: 30 kbps – Route via ATT. net, satellite • NASDA (Tokyo, JP) – NASA-NASDA removed private E 1 and installed private 3 mbps ATM service on 8 Feb 2000 -- for mission support only. » Performance typically 1. 8 mbps – 512 kbps science channel on private E 1 replaced by Trans. PAC for Science traffic – Performance over Trans. Pac: 850 kbps -- limited by NASDA Andy Germain CEOS-WGISS-NS-8 London, England April 2000 Page 16

Site Updates (cont. ) • Thailand (Sea Start) : – Testing started 9 -99 (FTP) -- Route improved 1 -00 – GSFC - >Sea. Start : » 1999: Median BH = 5 kbps, Typical daily peak = 186 kbps » 2000: Median BH = 54 kbps, Typical daily peak = 136 kbps – Sea. Start-> GSFC » Daily peak unchanged at 200 kbps, Median 10 - 50 » Route via Alter. Net-> NY, then Teleglobe via satellite – Serious congestion • Tokai Univ (Tokyo) : – Testing started 9 -99 (FTP) -- Results stable – Typical range 40 -375 kbps (median = 230 kbps) – Route initially via SINET, now IIJ from MAE-W Andy Germain CEOS-WGISS-NS-8 London, England April 2000 Page 22

Site Updates (cont. ) • UK – – – Now testing to UCL and Oxford, from GSFC and JPL Via JAnet and NASA dedicated ATM (VC = 2 Mbps) JAnet peering in NY: GSFC via Alternet, JPL via Abilene NASA ATM: Steady -- BH: Median = 1. 3 Mbps, Min = 1. 2 Mbps JAnet: Congested: Max = 2. 7 mbps, BH Median (via Abilene) = 500 kbps, (via Alternet) = 100 kbps, Min = 175 / 50 kbps. • UNEP – Now testing to 6 sites via Geneva to UNEP satellites: » Geneva: 300 -400 kbps » Norway: 100 -200 kbps » Beijing: 60 kbps » Bangkok two modes: 40 or 80 kbps » Nairobi: 120 kbps » Costa Rica: 90 kbps Andy Germain CEOS-WGISS-NS-8 London, England April 2000 Page 25
