[comp.protocols.tcp-ip] TCP tunnelled in IBM/SNA

ypinn@gpu.utcs.utoronto.ca (04/06/91)

Apologies, but there appears to be a bug in our Pnews command so that
the From: address for my previous message - and probably this one - is
marked as ypinn@gpu.utcs.utoronto.ca.  It should read either
craystn@gpu.utcs.utoronto.ca  {which is the machine the note was sent from},
or you can reach me at ypinn@gauss.clsc.utoronto.ca

Thanks

IBM can do this.  We were interested because we have an existing SNA
network, and needed to let two TCP/IP machines communicate over the
existing network.  Trouble is that you have to have a 370 to wrap
the IP packets AND a 370 to unwrap.  We had a 370 on one end of the link,
and would have had to put a 370 on the other end -- too expensive! :-)

I believe that there are several solutions for TCP/IP over/under/in
SNA. At the last Interop, I seem to recall hearing something about
cisco's being able to tunnel IP thru SNA (or perhaps real soon
then...;-) 

Also, the HP MPE/XL systems offer a link type for their TCP/IP that puts
TCP/IP over an SNA backbone. It might be able to do what you are
looking for.

I'm sure that your local HP and/or cisco rep people could go on and on
about these things ;-)
