How Does AVB Work?
Clocks: Accurate, Synchronized Communications
The commonly referenced network clock in every AVB-enabled device on a
network ensures that every device will have a very close representation of
what the precise time is in any given instance. After the devices communicate
with each other, one AVB device is selected as the best master clock and
communications proceed from talker endpoint to listener endpoint.
Endpoints: Talking and Listening
When an AVB talker endpoint device transmits one or more media streams to
the network, an AVB listener endpoint device receives one or more of those
streams from the network. The AVB bridge/switch acts as a conduit between
the two. Both the talker and listener endpoints request stream reservations and
the bridge between them fulfills those reservations, regulating the data streams
between both endpoints so they are receiving the correct data streams.
Step 1:
Talker endpoint advertises and listener endpoint receives the advertisement.

Step 2:
