Site Updates

• CCRS (Canada) Stable
• Routed stable -- direct peering between NISN and
  CANet3 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 ATT, 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

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 60kbps (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-gt13, RTT 210 -gt 110, Loss 3 -gt 10

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

Site Updates (cont.)

• CEO/JRC (Ispra, IT)
• BH Median about 140 Kbps average daily peak is
  about 1700 Kbps
• Route SWITCH (NY) to JRC
• AlterNet 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 E1 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 E1 replaced
  by TransPAC for Science traffic
• Performance over TransPac 850 kbps -- limited by
  NASDA

Site Updates (cont.)

• Thailand (Sea Start)
• Testing started 9-99 (FTP) -- Route improved 1-00
• GSFC - gtSeaStart
• 1999 Median BH 5 kbps, Typical daily peak
  186 kbps
• 2000 Median BH 54 kbps, Typical daily peak
  136 kbps
• SeaStart-gt GSFC
• Daily peak unchanged at 200 kbps, Median 10 - 50
• Route via AlterNet-gt NY, then Teleglobe via
  satellite
• Serious congestion

• Testing started 9-99 (FTP) -- Results stable
• Typical range 40-375 kbps (median 230 kbps)
• Route initially via SINET, now IIJ from MAE-W
