® and VoIP?
A:
See diagram below:
Q:
Why do I need different switches to use AVB?
A:
The most important enabler for AVB technology is the AVB bridge/switch.
Unlike current Ethernet switches, AVB switches have additional CPU processing
to handle the additional traffic shaping, time synchronization and QoS
requirements inherent in AVB-aware networks.
The AVB bridges/switches provide guarantees for time-sensitive, loss-sensitive,
real-time AV data transmission while allowing data, audio and video to share the
same network. The switches will only allow up to 75% of each network port to
be used for AVB traffic.
With AVB, VLANs and separate physical networks are options instead of
necessity. The bridge/switch automatically creates a VLAN for AVB traffic,
allowing AVB data packets to reach ports with non-AVB aware devices.
Therefore, AVB traffic will not pass through non-AVB switches.
