SWITCH is a foundation, sponsored by the government and the
Swiss universities, providing teleinformatics services to
all Swiss universities and to various research institutes by
connecting to national and international resources. SWITCH
started operation in October 1988.
SWITCHlan is a national backbone network which connects all
universities using leased lines with speeds between
128 kbit/s and 2 Mbit/s. Most other organizations are
connected via 64 kbit/sec. For routing on these national
leased lines SWITCH uses CISCO routers. The protocols
supported are DECnet, TCP/IP, X.25 and ISO CLNS.
All three Swiss supercomputers are connected to SWITCHlan.
Access to some library catalogs is already available; others
will join later.
International connections on the network level went
into operation in January 1990. The current state today is:
o+ Two lines with TCP/IP to CERN, each 2 Mbit/s. This
gives access to the European part of the Internet and
access to the NSFnet via the EASIgate T1 link to Cor-
nell.

o+ TCP/IP and ISO CLNS connection to Nice, France
with 64kbit/s; this link is the backup route to the
Internet/NSFnet.
o+ A TCP/IP 64 kbit/sec line to BelWue, a regional
research network in southern Germany.
A 64 kbit/sec connection to the COSINE/IXI pilot X.25 net-
work has been running since the first quarter of
1990. This infrastructure is mainly used for exchanging
X.400 messages, connecting to other X.500 DSAs and for
TCP/IP over X.25 and ISO CLNS over X.25 with the Euro-
pean Academic and Research Community.
SWITCHmail is the national X.400 MHS network which con-
nects the universities and research institutes to the
ADMD of the Swiss PTT and through COSINE-MHS to research MHS
networks in 19 countries. E-mail gateways to
EARN/BITNET, UUCP and Internet are also offered by SWITCH.
In RARE (Reseaux Associes pour la Recherche Europe-
enne, the European research network organisation), SWITCH
is an active partner in the COSINE MHS project as well
as in the COSINE pilot X.500 Directory Service pro-
ject and the COSINE Information Service project.

Any host on the network of a connected organization may
access the network, as long the usage complies with the use
policy of SWITCH.
