The University of Wisconsin has implemented the DOD Internet
protocols (FTP/SMTP/Telnet/TCP/IP) for IBM VM systems under con-
tract to IBM. This software package, called WISCNET, is owned by
IBM. IBM has licensed Wisconsin to distribute WISCNET, including
source code, to universities and colleges. The distribution will
begin in mid-June.
To receive WISCNET, a university or college must sign a
license agreement with the University of Wisconsin and pay a
one-time distribution fee of $500. Licenses may be obtained from
and should be returned to:

Documents describing WISCNET will be sent with licenses.
BRIEF OVERVIEW OF WISCNET
WISCNET includes:
(1) An implementation of the standard DOD protocols TCP and IP
under VM/SP Release 2 or 3.
(2) Implementations of the higher-level DOD protocols FTP, SMTP,
and Telnet.
(3) An interface between SENDFILE and SMTP.
(4) Interfaces from IP to the Ethernet and Pronet local area
networks (using a DACU as described below).
(5) An interace from IP to the Telenet public data network
(using a Series/1 as described below).
TCP/IP runs in a separate disconnected virtual machine on
the VM host. Similarly, each of SMTP, server FTP, and server
Telnet occupies a dedicated virtual machine. User FTP and user
Telnet run within a user's virtual machine under CMS. Virtual
machines communicate with one another using the Virtual Machine
Communication Facility (VMCF).
The VM software is written almost entirely in Pascal, with a
small amount of assembler-language support. Standard IBM-released
software is used throughout (i.e., no modified or unreleased sys-
tem software has been employed).
Local area network interfaces are available for Pronet (Pro-
teon Corp. - 10 Megabit/sec token ring) and Ethernet (Interlan -
10 Megabit/sec). The IBM host is connected to these local area
networks via a Device Access Control Unit (DACU), which is a
UNIBUS-to-channel adapter sold by IBM. There is also an inter-
face to the Telenet public data network, using an X.25 implemen-
tation running on a channel-attached Series/1 front end running
the RPS operating system. The latter interface allows CSNET IBM
VM hosts to connect to the DARPA Internet via Telenet.
