            SUNET, or  the  Swedish  University  Network,  interconnects
            local  and  regional networks at universities in Sweden. The
            goal of SUNET is to provide good  data  communications  that
            are  beneficial to the universities.  The network is used by
            researchers and teachers of all disciplines.  SUNET provides
            Swedish  academic  and research users with network resources
            for communications both within Sweden and around  the  world
            through  electronic  mail,  remote login, file transfer, and
            other methods.

            SUNET is a protocol-independent network  based  on  Ethernet
            (IEEE  802.3) interconnections. Currently only IP and DECnet
            (and EARN) are carried over the backbone. The  configuration
            of  SUNET  is  a  backbone  star  network centered at KTH in
            Stockholm with 64 kbps lines interconnecting the local  Eth-
            ernets  to one nation wide Ethernet. The lines are intercon-
            nected via remote bridges (Vitalink). Routers  are  used  to
            support  the  various  protocols: Cisco for IP and VAXes for
            DECnet (and EARN). SUNET also maintains a separate X.25 net-
            work.

            There are two interconnected  central  mail  hubs,  one  for
            IP/SMTP, RSCS/BSMTP and VMS/Mail and one for EAN/X.400 mail.

            There are (at least) 3000 IP hosts and 650 DECnets in SUNET.

            SUNET has international connections to
