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)

Chile - REUNA (www.reuna.cl)

• ATM backbone
• 10 nodes
• 10/60 Mbps
• 45 Mbps to AmPath

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
• ATT, Chilesat, ManquehueNet
• network deployed in 2003
• Fase I of the migration of REUNA to an optical
  production network

G-REUNA (Chile)RD activities

• Optical networking
• Equipping laboratories in UTFSM and USACH with
  the necessary equipment to perform applied
  research
• Applications development
• Real time resource sharing by distributing images
  of the applications that are running on different
  machines using multicast UDP.
• IPv6 Networking running these and other
  applications on similar networks implemented with
  IPv4 and IPv6.
• QoS for voice traffic in IPv4.
• i-education applications real time control
  experiments over the network
• Transference to industry sector
• Training courses for the Industry Sector
• Recommendation Publications on Project Web Page
• Collaboration with similar projects

GIGA Project (Brazil)

• Partnership between RNP and CPqD (former telco
  monopolys RD centre in Campinas, SP)
  www.rnp.br and www.cpqd.com.br
• Explore user control of optical fibre
  infrastructure
• interconnect 17 academic RD centres along the
  corridor Campinas - Rio de Janeiro (600 km)
• use of IP/DWDM with Ethernet framing over dark
  fibre
• Support RD 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 initial network design

• 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

GIGA Project RD activities

• 2/3 of the GIGA project budget is for RD
  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 RD 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
• RE institutions will need to upgrade their
  internal campus networks to Gigabit Ethernet

12
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 RD funding from the federal
  government
• Dark fibre needed

13
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 LAC, 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 LAC
• Requirement to link LAC optical networking to
  global initiatives
