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 :
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.
