LA&C = Latin American and the Caribbean
NREN = National Research and Education Network
The Latin America and Caribbean Region – LA&C
Geography
• South, Central and part of
North America, plus
Caribbean islands
• Over 10.000 km diameter
Demography
• Around 400 millions (more
than 40% in Brazil)
History
• Formerly mostly colonies of
Spain and Portugal and
autonomous since c. 1820
Languages
• Mostly Spanish and
Portuguese (just Brazil)
• Many amerindian languages
• English is first foreign
language

A Brief Story of Networking in LA&C
• Political, linguistic and cultural considerations have
traditionally led to considerable interaction between
countries within the region
However, networking has not followed this model:
• First connections (BITNET) starting 1986 using satellite
links between the US and each country separately
• Same topology inherited with transition to Internet
• Even multilateral initiatives (RedHUCyT in mid 90s and
AMPATH from 2001) have used traffic hubs in the US.
Recent developments (CLARA and ALICE, 2003) have
sought to alter this tendency.

Scientific User Community Needs in
LA&C
• The provision of high-capacity networking infrastructure
in LA&C countries is in good part to meet the demands of
international collaboration
• It is hoped that such provision can be made by a
combination of networking interconnections at the
regional/inter-regional levels, combined with renovation
of national NREN infrastructures

Global connectivity supports science
user communities
•
Scientific research increasingly dependent on access globally to
resources, collaborators, data, scientific instruments.
1. Access to scientific instruments with specific geo-location needs:
• optical telescopes: e.g., Gemini South and SOAR, Chile;
operated by US, Brazil and other countries
2. Unique instruments: impractical or unfeasible for each country to
“afford” for its own community:
• Large Hadron Collider (LHC) at CERN in Geneva: thousands of
collaborators around the world
3. Access to/collecting geo-specific data and getting it back for
analysis, visualisation, sharing
• Environmental data from the Amazon or Antarctica

Some of the scientific community connectivity
needs in LA&C
•
Some areas of interest:
– Astrophysics
• Argentina, Brazil, Chile
– e-VLBI
• Brazil, Chile, Mexico
– High Energy Nuclear Physics
• Brazil
– Geosciences
• Chile, Mexico
– Marine sciences
• Chile
– Environmental studies
• Brazil, Costa Rica
– Health and Biomedical applications
• Several countries
– Grid computing in general
Michael Stanton - APAN, Cairns, 2004

Global connectivity – tendencies
• Very high capacity (10s of Gbps) networks in core
countries and between them
• Increasingly regionalised networking
– European GEANT, South American CLARA, Asian
cluster efforts
– aggregate inter-continental bandwidth now
sometimes greater than continental bandwidth
– slow trend away from US as centre of the world
– many initiatives outside the US are engaging and
establishing leadership roles in connecting to the
world
– European – Asian connectivity
– European – Latin American connectivity

LA&C connectivity
• Phase 1: satellite communication with US hub
– bandwidth limited to 2 Mbps
• Phase 2: submarine optical cables
– initial bandwidth of 34 or 45 Mbps
– no upper limit in sight
– Phase 2A:
based on US hub
• AMPATH project (2001 - )
– Phase 2B:
region-centric
• CLARA network (2004 - )

First global conections from LA countries
Two “classical” phases of
connectivity:
• e-mail networks (BITNET,
UUCP)
• full Internet (IP) connectivity

Phase 2A: US-centric connectivity (2001 - )
AmPath
• uses Global Crossing
• 45 Mbps (one size fits all)
• connections to Miami, and
thence to Abilene (US NREN)
• connects Argentina, Brazil (2),
Chile, Panama, Venezuela
• other LA&C countries not so
benefited
AmPath
Mexico
• 3 cross-border connections to
US (Texas and California)
Michael Stanton - APAN, Cairns, 2004
14
Where do we go from here?
• AMPATH´s achievements
– Initial boost for Advanced Networking in LA
– Stimulus for advanced connectivity inside each
country
– Motivation for collaborative projects
BUT
• Why does LA&C communicate internally through
Miami?
• Why does LA&C communicate with other parts of the
world through the US?
Michael Stanton - APAN, Cairns, 2004
15
An alternative paradigm:
regional R&E networking
• Since the early 1990s great
efforts have been invested
in pan-European
networking.
• The present pan-European
network is GÉANT (2002-)
– currently the largest
capacity operational IP
network in the world
– built and managed by
DANTE

The European Commission’s @LIS initiative
•
Through @LIS programme the European Commission is
supporting improved connectivity to Latin America and the
Caribbean (LA&C)
•
@LIS: Alliance for the Information Society (2003-2005)
– 62.5 Million Euros for EU-LA&C on Information Society
Issues
– 10 Million Euros for Interconnecting Europe & LA&C
Research and Education communities
• Will interconnect LA&C-NRENs
Consequences:
– Formation of new NRENs in many LA&C countries
– Creation of the CLARA organisation of LA&C-NRENs
– ALICE project to support the building of the CLARA regional
network in Latin America

ALICE – Latin America Connected to Europe (2003-2006)
Project to build CLARA network, supported by the @LIS
programme (cost-sharing: EU 80% - LA&C 20%)
Coordinated by DANTE, with participation of NRENs from Italy,
France, Spain, Portugal and some LA&C countries, and CLARA
itself
– (target countries include present 14 CLARA members, plus
Bolivia, Columbia, Cuba and Honduras)

Expected CLARA network topology
•
•

Tijuana (Mexico) PoP to be
connected by dark fibre to
CENIC (California)
– access to US, Canada and
Asia - Pacific Rim
•
Initial backbone ring bandwidth
of 155 Mbps
Spur links at 10 to 45 Mbps
(Cuba at 4 Mbps by satellite)
Initial connection to Europe at
622 Mbps from Brazil
Network to be operated by
CLARA (through CUDI and RNP)

Expected also to support future
US funded international scientific
collaborations, including through
the IRNC program

IRNC - International Research Network Connections –
new NSF program launched in March, 2004
Synopsis of Program:
• Support for international collaboration for:
– access remote instruments, data, and computational resources
located throughout the world
– Remote access to large-scale science and engineering facilities
located both inside and outside the U.S. utilized by multinational research and education collaborations
• NSF expects to make awards to provide network connections
linking U.S. research networks with peer networks in other parts of
the world.
– Links funded by this program are intended to support science
and engineering research and education applications.
– Funded projects will enable state-of-the-art international
network services similar to and interconnected with those
currently offered or planned by domestic research networks.

CLARA response to IRNC
• CLARA’s major interest in this program is to leverage
good quality connectivity between the US and countries
served by the CLARA network through new links from the
US to backbone nodes of the CLARA network
• Cross-border dark fibre from Mexico to US
• Direct access to the “Southern Cone” countries
(Argentina-Brazil-Chile)
• CLARA believes the region’s interests are best served by
working with all US institutions proposing IRNC-funded
links to LA&C. We have therefore freely collaborated with
both proposals we have learned about.

Global R&E connectivity from LA&C
• The CLARA initiative is altering the way in which LA&C
countries communicate among themselves, and with
countries outside the region.
• In particular, LA&C traffic will be aggregated within the
region enabling more effective routing to other parts of
the world.
• The greatly improved connectivity will also support
improved and new collaborations with partners in other
regions.
