A Brief Story of Networking in Latin America
• 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.

First global conections from LA countries
Two “classical” phases of
connectivity:
• e-mail networks (BITNET,
UUCP)
• full Internet (IP) connectivity
• Table shows the dates of
the first connections for

Research and Education
Network)

Influence of telecommunications infrastructure
• Until very recently, the only available telecom
infrastructure for data communication was by satellite
– cost independent of distance
– no incentive for establishing links within the region, as
all countries were mainly interested in access to
global Internet
• Recent important changes (since late 1990s):
– end of state telecom monopoly in many countries
• competition and lower prices
• most LA NRENs replaced by commodity IP
providers (for economic or political reasons)
– building out of new infrastructure based on submarine
fibre optical cables
Michael Stanton - LISHEP 2004
5
Optical cable infra-structure
• Advances in optical transmission technologies have
recently made it possible to build very long distance
undersea communications systems based on DWDM
• In the late 1990s, several new DWDM (Dense
Wavelength Division Multiplexing) cable systems were
built, vastly increasing the installed capacity
• Principal new undersea cable operators in Latin America:
– Global Crossing
– Telecom Italia – Sparkle
– Telefonica International Wholesale Services - TIWS
(E-mergia)
– New World Networks (ARCOS cable)

Mexico - CUDI (www.cudi.edu.mx)
• Internal links at 155
Mbps
• 400 Mbps of int’l
connectivity
Michael Stanton - LISHEP 2004
15
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
– Connectivity needs, delayed till now due to high costs,
being solved
BUT
• Why does LA communicate internally through Miami?
• Why does LA communicate with other parts of the world
through the US?
Michael Stanton - LISHEP 2004
16
Another paradigm: Pan-European R&E networking
• In Europe, global networking also began with direct
BITNET and IP links to the US from separate countries
• Since the early 1990s great efforts have been invested in
pan-European networking, through the creation of a
series of regional backbone networks:
• These networks have been built and managed by
DANTE (Delivering Advanced Networking Technology to
Europe), with financing by European NRENs and the EU
• Four versions of the pan-European backbone network
– EuropaNET (1992-1997)
– TEN-34 (1997-1998)
– TEN-155 (1998-2001)
– GÉANT (2002- )
Michael Stanton - LISHEP 2004
17
TEN-34
• Trans-European
Network at 34
Mbps
• 20 countries
• operational in
1997
• backbone speed
inferior to internal
NREN links
(cost of int’l links)
Michael Stanton - LISHEP 2004
18
TEN-155
• Set up after
liberalisation and
harmonisation of
European telecom
industry
• Much cheaper int’l
connectivity within
Europe
• In some countries
liberalisation delayed
Michael Stanton - LISHEP 2004
19
GÉANT
• First network of the
“Bandwidth Age”
• 20-fold increase in
capacity over TEN-155
for the same cost
• Principal connections
are 10 and 2.5 Gbps
wavelengths
• Currently the largest
capacity operational IP
network in the world
Michael Stanton - LISHEP 2004
20
The @LIS iniciative
• Through GÉANT, the European R&E community enjoys
high bandwidth connectivity with N. America
• Initiatives already taken to improve connectivity to AsianPacific, Mediterranean and Latin American regions, with
support from the European Commission
• @LIS: Alliance for the Information Society (2003-2005)
– 62.5 Million Euros for EU-LA on Information Society
Issues
– 10 Million Euros for Interconnecting Europe & Latin
American Researchers
Michael Stanton - LISHEP 2004
21
CAESAR: Connecting All European and
South American Researchers.
European initiative to prepare for the @LIS program
• Promote EU-LA connectivity through regional connectivity within
LA plus a large pipe to Europe
• Participants: DANTE, NRENs of Spain and Portugal
• CAESAR Workshop 2002 in Toledo became starting point for
CLARA
– cooperative organisation for advanced networking in LA
– regional network:
feasibility study showed that @LIS budget sufficient to
establish advanced connectivity to all LA countries
• EU has agreed to 80% - 20% cost sharing between EU and LA
Michael Stanton - LISHEP 2004
22
• Association of NRENs in LA open to all LA Countries
– constituted in Uruguay (like LACNIC)
• CLARA is not limited to @LIS/CAESAR time scale and
restrictions
• Will connect LA to Europe and to other regions
• Cost to connect to the backbone will be the same for every
country at equal bandwidth
• Improve Internet2 connectivity by optimising LA
participation in AMPATH

Comments about CLARA
• CLARA responds to long-standing need for coordination
between LA NRENs.
• Builds on trust-building already carried out between
major partners
• Offers support for NREN building in other LA countries by
provision of support and int’l connectivity
Michael Stanton - LISHEP 2004
26
ALICE project: May 2003 to April 2006
ALICE - América Latina Interconectada Con Europa (2003-2006)
• Successor project to CAESAR
• Coordinated by DANTE, with participation of NRENs from Italy,
France, Spain, Portugal and the CLARA countries, and eventually
CLARA itself
• February 2003: technical definitions complete
• June 2003: Open tender for provisioning of links
• March 2004: Link contracts assigned
• May 2004: Network operational
Notes:
• DANTE is the project coordinator and will sign contracts with users
and providers
• CLARA is expected to represent interests of LA users in the
medium term (one year)

The Digital Divide in Latin America – the cost
of access circuits to the CLARA network
•The proposed costs of access connections from NRENs
to the CLARA backbone were initially extremely high in
the case of Central America and Colombia
•This has required that these countries’ NRENs
negotiate better pricing with their national provider

Final comments on the CLARA network
•
The network will provide connectivity for R&E collaboration traffic (i.e.
Internet 2 traffic) within the region and to other regions
– Initially connected to GÉANT (Europe)
– Expected soon to be connected via Tijuana (MX) to US networks
via Los Angeles peering point (agreement with CENIC)
• this also will provide access to APAN (Pacific Rim), as well as
other connected R&E networks
•
Initial backbone ring bandwidth of 155 Mbps
(connecting BR-AR-CL-PA-MX)
Initial connection to Europe at 622 Mbps from São Paulo
– RNP will use 155 Mbps of access capacity initially
CLARA network expected to be upgraded soon to support
international scientific collaborations between US and South America

Experimental networking in Latin America
• Advanced R&E networks provide for today’s connectivity
needs of the R&E community
• In future, with the growth of this community and its needs,
new solutions will need to be provided
• Such solutions are currently being developed and
demonstrated in experimental networking testbeds
• NSF 2002 classification of networking testbeds (beyond
Internet2)
– Experimental Infrastructure Networks (EIN)
• provides stable networking infrastructure for
application development and demonstration
– Networking Research Testbeds (NRT)
• permits development of networking technology

What comes next in Latin America?
•
•
•
For RNP and REUNA, experimental networking projects are
important for two reasons:
– it provides a testbed network for R&D
– provides experience in setting up and running a “facilitiesbased network”, instead of one based on service offerings
from telcos.
• only need the raw physical medium, or perhaps access
to lambdas (wavelengths)
• perhaps the only feasible way to build and use really
high capacity networks
Next step for RNP and REUNA is to transfer this experience to
their production networks
– Many well-known examples from other countries
A logical consequence is to seek Gbps or lambda networking
services for international collaboration.
Michael Stanton - LISHEP 2004
40
Conclusion
• Both international cooperation (through AmPath and
CLARA) and development of experimental networking
have percussions:
– they provide valuable opportunities for academic user
community in LA to collaborate with peer groups in
other countries
– they permit the acquiring and diffusion of experience
in advanced networking technologies, often absent in
LA countries
– they lead to the provision of high capacity
infrastructure networks for scientific cooperation
