            NORDUnet is a international backbone that interconnects  the
            Nordic  countries  Sweden (SUNET), Norway (UNINETT), Finland
            (FUNET), Denmark (DENET) and Iceland (SURIS).  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
