Organization and management
YUNAC is the major networking organization in Yugoslavia, which was set up in
1990 after two years of networking activities with aim to care for the
services provided to the end users. Members of YUNAC are Universities,
Research Institutes from the Academic and Commercial world. The network is
managed by Management Committee elected by the members of YUNAC Assembly. YUNAC
is organized as limited company. YUNAC is a national member of RARE, the
European Association of Research Networks and representative of Yugoslavia in
COSINE and RIPE - The European Internet Network. YUNAC is naming authority for
TLD .YU.
Infrastructure
YUNAC uses as communication infrastructure leased lines (mainly 9.6 Kbits and
some 48 Kbps) and PPSDN (Public Packet Switched Data Network). This
infrastructure is used for multiprotocol services: DECnet (Phase IV), X.400 and
NJE. All YUNAC nodes with X.400 services provide gateway services for e-mail to
the DECNET nodes. The number of connected hosts is cca 300.
YUNAC is connected via leased 64 Kbps line to the International X.25
Infrastructure (IXI) run by RARE and COSINE. The connection is implemented on
leased line between Wien and Ljubljana, Slovenia. The switch and WEP are
connected to the PPSDN of Yugoslavia - JUPAK. The switch and WEP (Well Known
Entry Point) are located in the YUNAC headquaters at the Jozef Stefan Institut
in Ljubljana. The connection to Internet is currently available via lines and
gateway services offered by DFN. The YUNAC switch provide TCP/IP over X.25
connection to the European Internet Network (RIPE).
Services
The services offered to the end users are: electronic mail, computer
conferencing, transfer of data, directory services, remote login, and
connection to the international networks EARN/BITNET, EUNET/USENET, Internet
(U S) via gateways. Regular information service connecting yugoslav users
abroad to the domestic source of information via e-mail and distribution
lists is also working well (Rok Press, BEST etc).
Other internationally connected networks in Yugoslavia
In Yugoslavia there are two additional networking activities which are parts of
the international networks i.e EARN and EUnet. The entry point to EARN/BITNET
network is located in Beograd. This entry point (an IBM machine located at the
Statistical Office of Serbia)is connected with leased 9.6 Kbps line to Linz,
Austria. The EARN entry point in Beograd provides gateway services for e-mail
to DECNET nodes trough leased line to a mvax machine (with PMDF and JNET sw)
located on premises of the Electrotechnical Faculty of Beograd.
The Eunet backbone for Yugoslavia is located in Ljubljana at Electrotechnical
faculty of Ljubljana University. The backbone host uses PPSDN and dial
facilities for connecting the EUnet backbone in Europe (Amsterdam). Gateway
services are not provided. Other Eunet hosts in the country use mainly UUCP and
dial up facilitees.
The Slovenian PTT is offering also mail box services to commercial users on
their host with X.400 facilities. This site is connected to the YUNAC WEP.
Addressing
All computers on YUNAC with X.400 facilities use X.400 address with an
appropriate Internet-style domain addresses maping i.e :
X.400: s=user;o=institution;p=ac;a=mail;c=yu
Internet: user@institution.ac.mail.yu
Decnet: user@host
EARN: user@host
Warning!!
Recently YUNAC had adopted a new addressing scheme. It will be announced in the
near future (implementation to start from December 1.) In the RFC 822 form will
disapear "ac.mail" !!
Future plans
DNS for .YU was set up recently (Internet address 153.5.1.1). Current DNS for
.YU from US will be moved in Europe. Currently an X.500 project is going on in
cooperation with the Slovenian PTT. Implementation to be offered to the users
next year.
