The Latin America and Caribbean Region – LA&C

Geography• South, Central and part of

North America, plus Caribbean islands

• Over 10.000 km diameterDemography• 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


ClaraClaraA 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 the ALICE project, 2003) have sought to alter this tendency.


ClaraClaraScientific 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 research and education network (NREN) infrastructures


ClaraClaraGlobal 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


ClaraClaraSome 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


ClaraClaraLA&C connectivity

• Phase 1: by satellite with US hub (up to 2000)– bandwidth limited to 2 Mbps

• Phase 2: submarine optical cables (from 2001)– 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 - )


ClaraClaraPhase 2A: US-centric connectivity (2001 - )

AmPath• uses Global Crossing• 45 Mbps (one size fits all)

for 3 years• connections to Miami, and

thence to Abilene (US NREN)• connects Argentina, Brazil (2),

Chile, Panama, Venezuela• other LA&C countries not so

benefited

Mexico• 3 cross-border connections to

US (Texas and California)

AmPath

until 2004until 2005until 2007


ClaraClaraWhere 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• It makes technical and economic sense to build a

regional network to interconnect LA&C countries

CLARA Network (RedCLARA)


ClaraClara

• Association of NRENs open to all LA&C Countries

– constituted in Uruguay (like LACNIC) in Dec 2003

• Created in response to EU’s @LIS initiative (2002-2006), but not limited to @LIS time scale and restrictions

• CLARA regional network will connect to Europe, North America and Asia-Pacific

Argentina (RETINA)

Brazil (RNP)

Chile (REUNA)

Costa Rica (CRNET)

Panama (REDCYT)Paraguay (ARANDU)Peru (RAAP)Uruguay (RAU)Venezuela (REACCIUN)

Ecuador (CEDIA)

El Salvador (RAICES)Guatemala (RAGIE)Mexico (CUDI)Nicaragua (RENIE)

CLARAMemberNRENs (July 2004)

(NRENs in formation indicated in RED)


ClaraClaraPhase 2B: region-centric networking

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) • August 2004: CLARA network to commence operations

• ALICE website:www.dante.net/alice

• ALICE brochure (in English, Spanish and Portuguese):www.dante.net/alice/ALICEbrochure.pdf


ClaraClaraExpected CLARA network topology

• Initially connected to Europe• Tijuana (Mexico) PoP planned 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 scientific collaborations involving US partners


ClaraClaraCurrent situation

• First links (Chile – Brazil – Spain) were activated on August 31st, 2004, permitting REUNA (Chile) to communicate with GÉANT and on to Abilene.

• Brazil connected from September 20th.• By October expected activation of complete 155 Mbps ring

(Brazil – Argentina – Chile – Panama – Mexico) and also spur link to Venezuela (45 Mbps)

• By December, add spurs to Paraguay, Peru, Uruguay• Central American connectivity from Mexico to El Salvador,

Guatemala, Nicaragua and Costa Rica currently in final stages of contract negotiation

13 of 14 CLARA member networks by early 2005


ClaraClaraIRNC - 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 multi-national 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.


ClaraClaraCLARA 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 between Mexico and 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. CLARA has therefore freely collaborated with both proposals for Latin American connections we have learned about.


ClaraClaraCLARA preferred topology for IRNC 2004

Rationale

• leverage the RedCLARA connectivity by links to RedCLARA PoPs

• “good” access to high demand centres in S. America

Components

• Dark fibre Mexico-US

• Link US-East to Brazil

• Link US-West or Mexico to Chile

• Link Brazil-Argentina-Chile

to US West Coast to US East Coast

Europe


ClaraClaraGlobal 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.
