Ethernet and Internet Protocol (IP) are *not* the same thing. The most common forms of IP are TCP and UDP, which are used whether you're browsing the web, transferring files, or doing about anything else. Ethernet is the hardware, and yes, it is compatible with RTnet - as far as I know, RTnet does not have drivers for any networking hardware other than ethernet. I'm not even certain RTnet protocol is compatible with other communication standards. RTnet protocol takes the place of IP. If "normal" (IP) traffic is to be transmitted, it is encapsulated within an RTnet packet until it gets to a computer that has a connection with the outside world. If you're bored - IP: http://www.faqs.org/rfcs/rfc791.html OSI (network) model: http://en.wikipedia.org/wiki/OSI_model RTnet: http://www.rts.uni-hannover.de/rtnet/doc.html The reason it's good to keep RTnet traffic away from "normal" traffic is that the greater number of packets on the network, the greater the chance that one will be delayed or lost. If an RTnet packet is lost or delayed, that is a Bad Thing. It's bad because it's no longer real-time.
