THE SAICYT OF VENEZUELA
In the early 1980s, the CONICIT (National Council for
Technological and Scientific Research), began work on a national
network, known as the SAICYT (Automated Technological and
Scientific Information System). Due to the lack of public X.25
facilities, it was agreed that CONICIT would establish their own
private network for the research community.
Initially the infrastructure was based on three X.25 GTE-Telenet
TP4000 nodes located in big cities. Other cities accessed the
system through GTE-Telenet TP3010 PADs. The connections were
based on dedicated lines running at 14.4 kbps. Each node had 16
synchronous and 16 asynchronous ports while each PAD had 8
asynchronous ports. In 1990, a process of upgrading the system
began with PADs being replaced by Cisco MGS routers.
The number of users on the network is around 2,000, but only 150
are active users. Most of the use is email, although some people
use the network to access their accounts in other countries to
reach commercial services such as Dialog or CompuServe.
Since 1990, a second network has been established. This
network, the REACCIUN (Cooperative Academic Network among
Research Centers and National Universities) is based on a TCP/IP
backbone with some X.25 gateways. The main node is a Sun 4/490
which acts as a centralized mail system at CONICIT headquarters.
Free mailboxes are assigned to each researcher registered by
CONICIT. Dedicated links to 6 national large universities and 8
mid-size research and academic institutions are planned.
Recently, a 19.2 kbps Internet link was established to the John
Von Neuman Center Network (New Jersey, USA), and the top-level
.VE domain was registered for the country. Although the link is
currently limited to FTP and Telnet sessions, when the link is
upgraded to 64 kbps, users will be able to take advantage of the
full range of TCP/IP services.
