REUNA: The Chilean Academic and Research Network
REUNA: Red Universitaria Nacional Chilena is a computer network developped by
the chilean universities, headed by the University of Chile. Its main goal is
to promote the development of cooperation among the different universities thru
the exchange of non-comercial information between their researchers, students
and teachers. Another important goal of the network is to facilitate the
interaction between chilean researchers and their colleagues in Europe, the US
and other countries, specially other Latin American countries.
The network has been built using existing research computing equipment and
vendor networking software: SNA, DECNET, UUCP; and recently: TCP/IP.
Additionally, in order to ensure connectivity among different pieces of the
network, some software has been developped at the Computer Center (CEC) of the
University of Chile which acts as center of the network.
REUNA is composed of three pieces. One connecting IBM mainframes is using SNA
software and uses leased phone lines to ensure a 24 hour service. Its services
include mail, file transfer, on-line messages and remote login. The second
piece connects Digital equipement using DECNET software over leased lines and
virtual X.25 links. Its services are the same as those of the SNA portion of
the network. Finally the third piece connects minis and micros using UUCP
software over dial-up connections. This part of the network supports only mail
and file transfer services (using encoding and packaging).
The three pieces are joined together at the Computer Center of the University
of Chile where two gateways using TCP/IP software are supported. The gateway
machines are an IBM mainframe and two Digital minis running simultaneously
their native vendor communications software and TCP/IP. Finally, a dedicated
satellite link to Maryland (USA) connects REUNA to BITNET where it has been
accepted as a cooperative network.
The full list of universities afiliated to REUNA is the following:
-Universidad de Chile
-Universidad Catlica de Chile
-Universidad de Concepcin
-Universidad de Santiago
-Universidad Catlica de Valparaso
-Universidad Federico Santa Mara
-Universidad de Tarapac
-Universidad de Antofagasta
-Universidad de La Serena
-Universidad Austral de Chile
-Universidad de Talca
The number of nodes at each university is variable running from 20 at the U. of
Chile to 1 at Tarapac or Antofagasta. Not all the universities have an internal
network so that several of them use the gateways of REUNA to interconnect their
machines of different type.
The network has agreed to evolve to TCP/IP protocols. In particular thanks to
the support of the National Commision for Science and Technology (CONICYT), the
network is now connected to the Internet thru SURANET in Maryland. A new
administration scheme is being developped so that CONICYT will take the lead in
teh administrative part and other Operation Centers will join the University of
Chile to improve the operationa3 ca+ab535t5es 6f the network.
Other interesting features of the Chilean Network is that the National
Bibliographic Service (RENIB) is connected to the network giving Bibliographic
research services thru the network. Of special iterest is also BITNIS a project
funded by the PAHO (Pan American Health Organization) allowing to selected
users of the network to use the National Library of Medecine (US). This use is
done thru a gateway designed and instaled by the University of Chile in the NIH
(US) seat of NLM.
