It also pro- vides internatinal connections to Major European and US net- works. NORDUnet started real operation in Autumn 1988. There are (at least) 4500 IP hosts and about 1000 DECnet hosts in the combined national networks that are intercon- nected by NORDUnet. The protocols supported as services across the backbone are IP, DECnet, EARN/NJE and X.25. NORDUnet connects through service agreements to Internet/NSFnet, EARN, HEPnet and EUnet. Pilot connections will be set up to COSINE/IXI X.25 and to EARN OSI. NORDUnet is a star with a center at KTH, Stockholm, Sweden. There are 64-kbit lines to RUNIT, Trondheim, Norway; UNI-C, Copenhagen, Denmark and HUT, Helsinki, Finland. There is also a 64 kbit line to CWI in Amsterdam, Holland and a 56 kbit line to JvNC, Princeton, USA. The (nordic) lines interconnect MAC-level remote bridges _________________________ The information in this section is provided in accor- dance with the copyright notice appearing at the front of this guide.
