RTnet's IPv4 _is_ compatible with standard implementations. Moreover, if
you can control the network traffic deterministically without the help
of RTnet on every node, you can also run mixed network segments without
loosing real-time guarantees on the RTnet nodes. But that mode is more
tricky and far more fragile than running a dedicated RTnet segment.

Further questions can also be directed to rtnet-users at
lists.sourceforge.net.
