ClaraClaraCurrent experimental optical networking projects in Latin America
Apart from the “production networks” run for the academic communities in Latin America, there are a small number of large scale networking testbed projects which in operation in the region. These include:
• Chile:– G-REUNA - Optical Networking and Advanced Applications
Testbed• Brazil:
– GIGA Project - Optical Networking and Advanced Applications Testbed
Both of these are a mixture of EIN (Experimental Infrastructure Network) and NRT (Networking Research Testbed)

G-REUNA: Optical Network design and layout (adapted from material provided by Walter Grote of UTFSM)• Backbone link between
Santiago and Valparaíso (200 Km)
• 1 node in Valparaíso, 3 in Santiago
• Dark fibre provided by 3 telco providers:– AT&T, Chilesat,
ManquehueNet
• network deployed in 2003• Fase I of the migration of
REUNA to an optical production network

ClaraClaraG-REUNA (Chile):R&D activities• Optical networking
– Equipping laboratories in UTFSM and USACH with the necessary equipment to perform applied research
• Applications development1. Real time resource sharing by distributing images of the
applications that are running on different machines using multicast UDP.
2. IPv6 Networking: running these and other applications on similar networks implemented with IPv4 and IPv6.
3. QoS for voice traffic in IPv4.4. i-education applications: real time control experiments
over the network5. Transference to industry sector
Training courses for the Industry Sector Recommendation Publications on Project Web Page Collaboration with similar projects

ClaraClaraGIGA Project (Brazil)
• Partnership between RNP and CPqD (former telco monopoly’s R&D centre in Campinas, SP) www.rnp.br and www.cpqd.com.br
• Explore user control of optical fibre infrastructure– interconnect 17 academic R&D centres along the corridor Campinas
- Rio de Janeiro (~600 km)– use of IP/DWDM with Ethernet framing over dark fibre
• Support R&D subprojects in optical and IP networking technology and advanced applications and services
• Industry participation (telcos lend the fibres; technology transfer of products and services required)
• Government funding for 3 years - started December 2002

• long-distance DWDM network between Campinas and Rio de Janeiro– up to 6 lambdas (lightpaths) per link
• CWDM metro networks (MANs) in Rio, S. Paulo and Campinas
• equipment:– WDM: from Padtec (Brazil)– IP/N-GbE: from Extreme Networks
• network operational in May 2004

ClaraClaraGIGA Project: R&D activities
• 2/3 of the GIGA project budget is for R&D activities in the following areas:– Optical networking (CPqD)– Network protocols and services (RNP)– Experimental telecommunications services (CPqD)– Scientific Services and Applications (RNP)
• Most of the R&D activities are contracted out to research groups in the university community (at 45 different institutions in Brazil)– Incentives for technology transfer to industry– The network may also be used for the development and/or
demonstration of high capacity networking applications by scientific researchers in various areas (HEP, computational biology, earth sciences, etc).

ClaraClaraFuture RNP production network
• By 2005, RNP expects to move to a new “facilities-based” backbone network of at least 1 Gbps capacity, based on GIGA project experience:– long-distance links based on acquiring “capacity”, in the form
of lambdas (lightpaths) or dark fibre– local access in metropolitan areas based on the use of dark
fibre and cheap Gigabit Ethernet switches• cooperation between local institutions is vital for the
setting up of these metro networks• R&E institutions will need to upgrade their internal campus
networks to Gigabit Ethernet

ClaraClaraFuture Expansion of the Experimental Network
• The current experimental network is confined to the SE region of Brazil, but involves nationwide participation
• Since January, the ministers of Communications and Science & Technology are from the NE region of Brazil
• They have recently come out strongly in favour of extending the experimental network to other parts of Brazil, beginning in the NE– Equipment and R&D funding from the federal
government– Dark fibre needed
Michael Stanton - CCIRN 200413
ClaraClaraDark fibre: sharing infrastructure
• RNP would like to create synergy between this extension of the experimental network and technology transfer to production network– Telcos will lend but not rent dark fibre to RNP
• Problem of “strings” attached to dark fibre lent by telcos
– Possible alternatives from state-owned energy utilities
• Ongoing contacts with electrical and oil utilities

ClaraClaraConclusion
• Optical infrastructure makes possible and desirable new ways of building advanced networks
• In LA&C, optical networking has begun first in Chile and Brazil with experimental (testbed) networks, with developments both in networking technologies and advanced applications
• In both countries there is a definite intention to migrate optical networking experience to the production network in the short term
• User demand for high-capacity connectivity services in several countries in LA&C
• Requirement to link LA&C optical networking to global initiatives
