Hi to everybody,
I'm working with RtNet for my thesis in Software Engineer and I would know
how UDP is implemented in RTNet.
My main task is the meaning of "realtime" in UDP protocol. Maybe a message
sent using UDP under RtNet it will always arrive because RtNet will garantee
the arrival? or if the message does not arrive in the timeline it does not
arrive at all?
Searching in this mailing list I find other people with the same problems
and the answer it was:
o the way the UDP/IP stack and the drivers are implemented (bounded
locking times, the usage of a RTOS API)
o the media access protocol for Ethernet (RTmac) which avoids the
undeterministic CSMA/CD mechanism
but my question is: in which way the UDP/IP stack is implemented? and the
drivers how they work? and how it works the RTmac?
I'using RtNet v0.2.6, RTAI v24.1.10, RedHat with 2.4.19Kernel and a Network
Adapter based on 8139Realtek.
Thanks in advance.
