AVB Questions and Answers
Q: How does AVB fit with other technology like CobraNet® and VoIP?
A: See diagram below:
Q: Why do I need dierent 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 trac 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 trac.
With AVB, VLANs and separate physical networks are options instead of
necessity. The bridge/switch automatically creates a VLAN for AVB trac,
allowing AVB data packets to reach ports with non-AVB aware devices.
Therefore, AVB trac will not pass through non-AVB switches.
Q: Is there a list of approved AVB switches for Tesira systems?
A: There are several AVB-capable switches currently available. Below is a partial
list. For up-to-date information, please visit Cornerstone, our online support
