Hello, Jan and Hans. Thanks a lot for the answer and helps. I will have a further look about the vnic etc.

I have installed RTAI/RTNET on 192.168.1.101, which connects to 192.168.1.1 ( a WLAN router to the outside world) and another laptop also on the lan (192.168.1.100 via hifi) by using "rtroute solicit 192.168.1.1" dev rteth0, now I can rtping 192.168.1.1. I have anoter machine in my lab which run Redhat 7.2 (142.104.x.x) so I add another net route " rtroute add 142.0.0.0 netmask 255.0.0.0 dev 192.168.1.1 " then I use RTPing 142.104.x.x and there is no response back. Are there anything missing or did I do something wrong? As said, is there a way that I can add a net route entry to all non-local hosts by using rtroute, such as routing all traffic to my default gateway 192.168.1.1 via the interface rteth0. I am thinking to do a prelimary experiments about network traffic control in RTAI kenel, for example, to creat two RT tasks with seperate RTsocket and control the outgoing traffic for each of them for example, 100kbits for the first one and 200kbits for the 2nd one? have anybody tried this using RTNET, I think I need to change some internal RTNET things to do that. do not understand that much now. Is this feasible? Can I also do some control on the incoming traffic as well? like dedicated buffer control for different socket for example. Thanks a lot.
