Thanks for many replies. I learned a lot about VAX clustering. I will use

to
emulate HSC controllers with LAVC access?
When Matt Burke and I were discussing the CI concept, we picked IP
Multicast as transport for the very specific reason that all modern host
systems will have natural user mode programming access to implement
this functionality. Attempting to create your own Ethernet multicast
protocol (non-IP based) will have portability complexities on different
platforms due to the fact different platforms have varying support (and
potentially require privilege) to present and/or receive raw Ethernet
frames to/from a LAN.
I don't know for sure, but I assume that Tim just meant that he will let
LAVC do as LAVC does, without him doing anything.
And LAVC itself might be using ethernet multicasting.
This is no more an issue than DECnet communication, which also requires
access to the raw ethernet.
