TCP/IP and SNA

[Richard Croucher]

There are a number of possibilities for mixing TCP/IP and SNA networks.
The ones I have come across are:
o-      Use a TCP/IP telnet to SNA 3274 gateway convertor.  This looks like
        a telnet host on Ethernet to UNIX systems, and looks like a 3274
        terminal controller (either remote or channel attached) to the
        IBM mainframe.  Products which provide this are available from
        Mietek or software from SUN.

o-      Add TCP/IP software to the Mainframe host and use that as a gateway
        between UNIX and SNA users.  Software and hardware available from
        Fibronics, ACC, even IBM.

o-      To use an existing SNA network to link together a number of remote
        TCP/IP networks requires something like the SNA/IP gateway available
        from Brixton Systems.  This is a HW/SW package that plugs into a
        VME based SUN.  It uses IP routing SW to route the packets across
        the SNA network, by emulating an IBM Front End Processor.
o-      Use a UNIX host which can also provide a very high degree of
        SNA interoperability.
