About a week ago, I posted this article to INFO-VAX and BIG-LAN from
my BITNET attached host.  I saw the article appear on BIG-LAN but not
on this list.  This is a re-posting.  My apologies if you've already
seen it.

Hello NetLand!
     
I am soliciting commentary on experiences/gut-feelings with respect to
running TCP/IP terminal servers as the exclusive terminal connection
method for VAX/VMS systems.  We at York University are in the process
of putting together a budget wish-list for the coming fiscal year and
some of the items are replacement systems for our UNIBUS based VAXen.
DEC's own corporate strategy is leaning heavily toward LAT based terminal
servers.  However, since DEC is keeping the LAT protocol proprietary it
has no competitive market to drive prices down (good for DEC, not so good
for us penny-pinched university types).  In addition, a TCP/IP based
solution makes it possible for any given terminal to also speak to a
non-VMS host.  This has increasingly greater attraction to us but
all the same, in this instance, the primary concern IS to provide access
to the VMS boxen.
     
I suppose my primary concern in the matter is the performance aspect.
Are any of the commercially available TCP/IP-on-VMS implementations
built to handle 70-80 concurrent TELNET or rlogin connections on
a MicroVAX 3000 scale CPU?  Presently DEC has entered into cooperative
marketting agreements with TWG and NRC for the WIN/TCP and Fusion
products.  I welcome any user-experience information with either of
these products.  Any other products that anyone cares to recommend or
warn me away from are also of interest (FTP Software, Excelan?).
     
If you feel that you have a particularly inflamatory comment that you
do not wish to share with the rest of the net, please reply to me
directly and indicate that you do not wish to be quoted.  I promise
discretion.  In general, you can mail to me directly and I will
summarize back to the lists to which this message is posted.
     
Thank you in advance for any responses,
Eriks
