Anybody know something about IEEE 802.1 AVB ?

I'm also
somewhat interested in the network part, I feel IPv6 could
help
a lot. It supports autoconfiguration and it has
decent multicast
support, so it would be possible to broadcast/multicast the streams
on
the net (LAN). This could be useful if you want
to access the stream
at
a mixing console for a life setup and
simultaneously record it on a
computer.
Put another way, it would be far more compatible if this were done
over
an IP stream rather than any native ethernet stream, not least it
could use
any ethernet driver that linux supports rather than a small subset of
them.
I am sure this will make a lot of the lower layer people turn away
from the
project which is unfortunate but there are a lot of issues associated
with
attempting to do this over a native ethernet connection: it would need
some
consideration to be given to data loss and recovery which are already
native
to the higher layers.
Perhaps the project needs to be specified with regards to its goals?
If the
idea is just to have Ethernet supported as an interface then fine,
native
access is probably fine. If the idea is to have Ethernet supported as
a
transport the reusing what is already available makes a lot of sense.
To
start with, being able to use any Ethernet card already means it can
be
done cheaply. Limiting it to selected devices perhaps not so as it
would
require the purchase of specific cards.
Anyway, to paraphrase a joke a friend made recently, he drove to a
Linux
Audio Conference where the people there said to him "what are those
round
things on the side of your car?". He said at least when we went to the
networking conferences people knowingly said "ah, I know what _they_
are.
They're called wheels..... I've seen those before."
Kind regards, nick
