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.
