[comp.protocols.misc] LAT and DECNET protocol specs.

mark@jarthur.Claremont.EDU (Mark Anderson) (03/11/91)

I hope that these are appropriate groups and apologize in advance if I have
missed a FAQ somewhere with this one in it.  

I need everything I can find on the DEC LAT protocol. DECNET stuff would
also be nice, but not as important. I realize that it is a licensed product
of Digital Equipment Company, but was hoping to find some sort of primer for
the protocol available without having to license the right to use from DEC.

The reason I need this is that am trying to write a program to measure among
other things the load on an ethernet caused by terminal servers, and the
data flow rate that is sent. For this I would like to be able to examine
ethernet packets and measure the character rate (data flow) for several
different protocols. Telnet and rlogin are easy to find information on, but
we also are running DEC LAT servers on our network. I would like to be able
to look at ( and partially decode ) these packets as well, so I can get a
measurement of the comparative throughput (per login) that we are actually
getting. I know that this is a tricky thing to do, and I'm probably doing to
much work for too little use, but it's worth a shot. 

Any pointers, references or anything would be welcome. 

Thank you.
