011.30 Brazil by Eduardo Tadao Takahashi Rede Nacional de Pesquisa Brazil has just completed the installation of TCP/IP backbone. The backbone consists of (mostly) 9.6 kbps dedicated lines interconnecting 11 major cities in the country: Brasilia, Rio de Janeiro, Sao Paulo, Porto Alegre, Belem, Fortaleza, Salvador, Belo Horizonte, Recife, Curitiba, and Florianopolis. Links between Brasilia-Sao Paulo, Brasilia-Rio de Janeiro, and Sao Paulo-Rio de Janeiro are being upgraded to 64 kbps. Three dedicated connections to the US also operate at 64 kbps and a link to Argentina will soon be installed. Routing has been done utilizing UNIX workstations, soon to be replaced by dedicated, multi-protocol routers. An embryonic National Operations Center has started activities in Sao Paulo, while an Information Center is being set up in Rio de Janeiro. Another major activity carried out recently has had to do with computational and networking support for the Earth Summit (also known as UNCED'92 or RIO-92), the gigantic UN Conference held in Rio de Janeiro in June. Such support has included: - a dedicated, "closed" information system (implemented by DEC) for the OFFICIAL SPACE under the direct operation of the UN Conference organization staff. - a metropolitan network to support activities of the GLOBAL FORUM (the forum of NGOs), with gateways to international networks such as PEACENET and ECONET through the ALTERNEX node. - the installation of two special-purpose nodes, one in Belem and another in Natal. The Belem node centralizes communications in the Amazon Basin with neighboring countries, within the realm of activities of the Treaty of the Amazon signed in 1983. The Natal node centralizes communications among Brazilian institutions participating in the so-called DRYNET project, which aims to interconnect research institutions in arid and semi-arid regions in Brazil (the Caatinga), Argentina (Gran Chaco), and Chile (Norte Chico) Further information about the Conference and, in particular, about what has been planned for AGENDA-21 (as the main result of the Earth Summit), can be found in the list . A topic of specific interest to networkers is the set of directives issued by UNCED'92 for the implementation of the so-called AGIS, the Agenda-21 Information System, which is intended to be distributed among several countries while being remotely accessible in an uniform way via networks.
