Roman, This was dicussed earlier on this list. I found one disdavantage of using multicast. My packet size or structure kept growing as I added more computers on the network that are **not** image generators but pcs used as flight test engineer station or fcs monitoring station etc. Why should image generators receive data that is not intended for it and vice versa. So I find non-blocking udp fast enough while maintaining packet sizes to the minmum required and I suppose bandwidth requirements are not too high to cause perceptible delays. Regards Ranga

I use the '--fdm=external' and '--native_fdm=...' options (--native_fmd= uses the same parameters as --native). I did make some changes to Network/native_fdm.cxx to properly manage the byte-order issues, but it works like a champ. IMHO, --native_fdm= has a cleaner interface than does --native=. To see the data structure that the FDM needs to generate, look in Network/raw_fdm.hxx. Jonathan Polley p.s. I have submitted my edits.
