I have been doing some reading on audio over IP (or
networking of any
kind) and one of the things that comes up from time to time is collisions.
Anything I read about ethernet talks about collisions and how to deal with
them. When I was thinking of a point to point layer two setup, my first
thought was there should be no collisions. Having read all the AES67 and
other layer 3 protocols there does not seem to be mention of collisions
really. My thought is that on a modern wired network there should be no
collisions at all. The closest thing would be a delay at a switch while it
transmitted another packet that in a hub would have been a collision.
So my thought is that AoIP at low latencies depends on a local net with no
collision possible. Am I making sense? or am I missing something?
just to add my two cents for ideas:
In robotic there is a open source solution for linux kernels called rtnet,
which has exactly the purpose to prevent collision and garantee low latency
over network:
http://www.rtnet.org/
I tried this to get my autopianoplayer with less jitter and speak with the
microchip dsPIC board escher over Ethernet,( even I got other problems...)
I think using rtnet would be nice for a open source simple audio-card over
Ethernet.
