Protocol description
- IEEE 1722: AVB Transport protocol

Embedded Implementations
PC Implementations
- Mac OS ≥ 10.9 (Mavericks): AVB natively supported with internal Ethernet adapter on all recent Macs (=with Thunderbolt port); Screenshots
- Windows: Echo Streamware; custom ethernet card, driver for AVB ⇄ ASIO
- Linux: Open-AVB for Intel I210 ethernet cards; very active development; no complete plug-and-play implementation, mainly hardware drivers and PTP synchronization (only a few audio examples for IEEE 1722 transport protocol)
- Linux/Windows/Mac 1722.1 controller library & cmd line app: https://github.com/audioscience/avdecc-lib
Switches
- Extreme Networks – high end, very mature AVB support reported; additional license for AVB required
- ∑ ~$1000 for cheapest 8 port switch (X440-8t)
- only X440-8t is fanless
- TSL MES-1 – since April 2014; quite expensive
- Netgear – AVB support reportedly limited/problematic, additional license for AVB required
- DSP4YOU AVB-SW – development board, low-cost
- Lab X Switch – discontinued
- Brick – 100 Mbps, PoE; apparently based on the DSP4YOU switch; available for pre-order
- New (August 2014): MOTU AVB Switch, Gigabit, 5 ports, €315 – XMOS compatibility unknown
Alternatives to AVB for audio
- Ethernet-based
- Dante – does not require special switches; AVB compatibility announced
- CobraNet
- EtherSound
- AES-10 (MADI) – strongly supported by studio hardware manufacturers, no low-cost or open implementations
- ADAT Lightpipe – 8 channels max, chipsets discontinued
