- 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.
