You can use normal hubs for connecting your stations. RTmac will
guarantee that no collisions will occur. You may even use switches
(preferebly simple 8-port variants because they are fully
hardware-based), but this will only add about 20 us additional delay to
every packet and you will still have to use RTmac for real
_deterministic_ networking.
