            NORDUnet is a collaboration between  the  national  research
            networks  in  Denmark,  Finland, Iceland, Norway and Sweden.
            Its purpose is to provide the national research  and  educa-
            tion  communities with an efficient networking service which
            ensures coherence of the national R & D  networks  and  con-
            nects  these  to  similar networks in the rest of Europe and
            the world.

            NORDUnet is organized as a consortium agreement between  the
            national  networks  DENet,  FUNET, SUNET, SURIS and UNINETT.
            The administration is an integral part of UNI-C in Denmark.

            NORDUnet has contracted its  work  mainly  to  the  national
            organizations.   The network operations center has been con-
            tracted to KTH/SUNET. It is their responsibility to  monitor
            the  service,  configure  the  Cisco routers (IP) as well as
            coordinate operational issues.   The  X.25  operations  have
            been  contracted  to UNINETT and DECNET operations to UNI-C.
            Overall  technical  coordination  has  been  contracted   to
            VTKK/FUNET.

            NORDUnet has five points of presence, one  in  each  of  the
            Nordic countries.

            NORDUnet provides IP, DECNET, X.25 and  CLNS  layer  3  ser-
            vices, in this order of volume. NORDUnet leases bandwidth in
            form raw lines and adds value by providing the network layer
            protocols  in  a coordinated fashion with equipment operated
            through various contracts.  The national networks which  are
            the  NORDUnet  customers  see  it as a "NORDUnet plug" which
            provides different service "pins".

            NJE traffic is transported over TCP/IP. The CLNS  (including
            DECNET Phase V) pilot traffic is carried by the same Cisco's
            as the production traffic.   The  external  connections  are
            mainly  based  on  Cisco  routers. NORDUnet runs IP and CLNS
            protocols to the US and IP, CLNS and DECNET  IV  to  Europe.
            X.25 connectivity to Europe is provided via a direct connec-
            tion to the IXI network.

            There are app. 60.000 IP hosts, 5000 DECnet hosts,  and  100
            EARN  hosts  in the Nordic national networks that are inter-
            connected  by  NORDUnet.   NORDUnet  connects  the  national
            Nordic  networks  to  Internet, Ebone, EASInet, EARN/BITNET,
            EUnet, HEPnet, SPAN and IXI.
