I believe the current HITL system uses TCP/IP over Ethernet; since we
use VEOS that is what we use also. As I understand it, the next
generation of system (referred to as Moses or VEOS 2) will also use
Ethernet as the physical transport layer but may use something other
than TCP/IP on top.  Some network utilization experiments using a
network "sniffer" that were done some months ago indicated a much
higher usage than I expected, given the relative simplicity of the
world.  Some of the other folks on the VR project here at Boeing have
talked about using a small number of large parallel machines networked
together using a mix of HIPPI channels and Ultranet, since we are going
to have the hardware for use in other applications anyway.
