[comp.protocols.tcp-ip] lattisnet

I've been testing the LattisNet product for the last 2 months.
It seems to work just fine.

There was some badmouthing of this product by a-large-computer-company,
saying that it did not run at 10MB. I have seen no reason to feel that
might be true.  I have tested a sun 3/60 connected via LattisNet to
Harvard's backbone & see no change in throughput or error counts when
compaired to a sun direct connected to the backbone.

We've been using Lattisnet for about fifty machines, and it
seems to work pretty well.  When it was first installed, there
were some packet dropping problems, and they came out and
installed some sort of additional buffering.  Perhaps you
have an older version, or else the lower cost, less buffered
version.  Maybe when the machine count goes to a hundred,
we might have a different story to tell, (ie its time to
buffer more.)  However, single point to point transfers seem
to run as fast between machines on the Lattisnet as those
not on it.  This was tried only with sun 3/260's and SGI
irises, so far.

We've been using Lattisnet for quite some time now (2 years?).  In fact, we 
were one of their initial beta testers.  We aren't using the thinwire stuff 
yet, but we are using their system over our IBM cabling system and over fiber. 
 We have a few hundred connections to multiple lattisnets and have never had a 
single hardware failure.  Our campus backbone is also a lattisnet box.

I can't say enough good things about the product.  We are very happy with it 
and we are using it in almost all future ethernet connections, as well as 
converting many old connections to it.  It's ease of use and maintenance are 
great since it gives us a star shaped ethernet in centralized wire closets.  
As far as cost goes, it is a bit more expensive.  However, we feel the 
additional cost is small compared to what we get in maintainability.  In the 
long run it may even be cheaper when we factor in technician time for 
installation and maintenance.
