Current 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)

Optical networking
– Equipping laboratories in UTFSM and USACH with the
necessary equipment to perform applied research
Applications development
1. 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 network
5. Transference to industry sector

GIGA 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

GIGA 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).

Future 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

Future 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 2004

Dark 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

Conclusion
• 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
