Sioux Falls, SD, US

May 2001


Network performance testing highlights

Daily results now online:

http://corn.eos.nasa.gov/performance/Net_Health/CEOS_list.html

Implemented a European test source at UNEP-Norway

Connected via Nordunet -- Testing to UNEP sites, US, UK, ESRIN

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

Netherlands (KNMI): tested Sept to Nov '00

Russia: IRS-RAS tested Oct to Dec '00

Thailand: SeaStart stopped Nov ‘00, GISTDA added Oct ‘00

Note: Check Ethernet Auto-negotiation

Site updates

Argentina (CONAE): Steady since July '00

Thruput about 300 kbps via Telintar (thru NY)

Was 200 kbps previously (20 kbps in ‘96)

Australia (CSIRO): Testing Resumed June '00

Performance 50-250 kbps until mid August '00, then 100-800 kbps

Route via Optus

Brazil (INPE - Sao Paolo) : Upgrade to ANSP Jan '01

NASA dedicated 64kbps circuit (IDN) discontinued Jan '01

Via ANSP (HSB): 25-1450 kbps (median 550)

Was 10-650 kbps (median 25!) previously via Embratel

Canada (CCRS- Ottawa): Improved Jan '01

Peaks now over 5 mbps (was about 4 mbps) -- BHM 3.4 vs. 2.9

But congestion is evident too -- daily worst now 1.7 mbps (was 2.3)

Route stable -- direct peering between NISN and CA*Net3 in Chicago

Site Updates


Site updates cont

China: START Regional Center -- Still down

No performance testing since Aug '99 (was 18 kbps)-- resume??

Route via AT&T, satellite -- appears highly congested

APAN would be better

Germany:

DLR (Oberpfaffenhofen):

Test host unresponsive since July '99

Route via MAE-E, UUNet to NY, DFN

Eumetsat (Darmstadt):

Performance testing still not running -- try again?

Route via KPNQwest to Darmstadt

Israel: Testing resumed Nov-Dec '00:

Performance 0.2 - 1.7 mbps (was 1.7 mbps steady)

Route via direct peering with ILAN in Chicago

Datasink stopped in Dec 00 -- will try to restart again.

Site Updates (cont.)


Site updates cont1

Italy (ESRIN - Frascati): Congestion Increasing

BHM from GSFC dropped to 400 kbps (was 970) (55 kbps prev)

Typical daily range 100-1500 kbps (was 350-1500 kbps)

Route via MAX, Abilene to NY, TEN-155, GARR

Also testing from Norway :

Thruput 500-1300 kbps via UNInet, Nordunet, TEN-155, GARR

Datasink stopped Jan '01 -- will request restart

Italy (CEO/JRC - Ispra): Restarted Feb '01

BH Median decreased to about 500 kbps (was 900 Kbps);

average daily peak is down to about 650 kbps (was 1700)

New Route: AlterNet all the way! Reduced congestion.

Malaysia (UKM): Testing stopped June '00

Thruput tested 19-20 Jan '00: 30 kbps

Route via ATT.net, satellite

Site Updates (cont.)


Site updates cont2

Japan (NASDA EOC - Hatoyama): 2 routes

NASA-NASDA removed private E1 and installed private 3 mbps ATM service in Feb '00 -- for mission support only.

Performance stable - typically 1.6 mbps

Now using TransPAC via STAR TAP (Chicago) for Science traffic

Performance stable - typically 1.15 Mbps

Netherlands (KNMI): testing 12-Sept to 8-Nov '00

Route from GSFC via Abilene to SurfNet in NY

Performance initially 0.9-1.8 mbps

was 10-18 mbps to SurfNet Core

Upgrades planned this summer -- will resume testing

Russia (IRE-RAS - Moscow): Testing Oct-Dec ‘00

Current Route is via Internet -- Rostelecom in NY

Other possibilities: MIRnet, or NASA dedicated circuit

Performance was BHM = 75 kbps, Daily range = 13 - 30 kbps

Site Updates (cont.)


Site updates cont3

Russia (CAO - Moscow): SAGE III Project

Route currently via NY to Rostelecom/RBnet -- Congestion increased

plan to use NASA dedicated circuit

Performance typically 2-76 kbps; median 18 kbps (was 41)

Thailand

AIT: Testing via 2 routes -- similar performance now:

Abilene-TransPac-APAN: 60-204 kbps (BH median 170)

Commodity Route: UUNet-Teleglobe: 15-300 kbps (median 150)

Was 8-160 kbps (BH median 15) via UUNet-WorldNet:

SeaStart : Testing stopped Nov '00

June-Nov 00: Median BH = 20 kbps, Typical daily peak = 100 kbps

Route via Commodity Internet -> NY, then Teleglobe via satellite

Serious congestion

Commodity Route: UUNet-Teleglobe-Inet

75-470 kbps (BH median 160)

Site Updates (cont.)


Site updates cont4

UK

From GSFC: via Abilene to JAnet in NY

JAnet core (London): now 8-11 Mbps

was 16-23 Mbps typ

NY peering reconfigured

UCL: 3-5 mbps

Was 600-1400 kbps via NASA dedicated E1

E1 circuit removed

Oxford: 3-5.5 mbps

Was 21 kbps - 3.2 mbps via commodity network

RAL: 10-15 mbps

From UNEP Norway: UNInet to Nordunet to TEN-155 to JAnet

655-1200 kbps

Site Updates (cont.)


Site updates cont5

UNEP: testing to 6 sites

Norway: route from GSFC via Teleglobe, Nordunet, UNInet

Performance from GSFC improved December '00

Was 25-115 kbps, now 630-2900 kbps!

Began testing from Norway to UNEP and other sites

Geneva: route from GSFC via BBNplanet, Swisscom, IPplus

Performance from GSFC improved April '01

Was 28-435 kbps, now 19-1250 kbps! Still heavily congested

From Norway: Double UNEP satellite hop! 52-113 kbps

Nairobi, Bejing: via satellite from Norway

Beijing: Performance improved March 10

From GSFC: Was 12-110 kbps, now 17-165

Will Start testing from Norway

Nairobi: testing stopped 9 '00 -- performance was 75-500 kbps

Bangkok via satellite from Geneva

From GSFC improved to 15-110 kbps Apr '01 -- was 15-55

From Norway: improved to 30-100 kbps Apr '01 -- was 20-55
