RE: SNA over TCP/IP

["Carl Galgano" <cgalgano2@xxxxxxxxxxxxxxxxx>]

Chris:
I agree, SNADS is rock solid.  I still prefer some SNA stuff for some
things.  On our internal network, ALL the DDM traffic is still defined as
SNA not IP.  I see no good reason to change.  Now, I would NEVER advocate we
go back to SNA for terminal emulation or other things, but SNA is/was ROCK
SOLID.

Once I had to send a 2GB save file across a WAN.  This was a 128k private
Frame Relay connection.  We also have a 56K PTP Leased line from V.35 to
V.35 on the two AS400's.  Because of the FR being 2+ times faster and FTP
has less overhead than SNADS, I thought that I would FTP the file.  After
two attempts failed 2hrs into transmission, with no recovery possible,  I
decided to SNADS the file.  Took 4 hours and completed with out a hitch.  I
now am running *anynet over the FR and SNADS works great.  FTP still fails
about half way thru.  Seems our carrier has issues with us pushing data past
our purchased rate which our routers will use all available band with on the
FR circuit.  Yes the SNADS get interrupted during the transfer but does not
drop, it RECOVERS and CONTINUES.  FTP drops the connection and it is back to
square one.
