AVB

AVB “Audio Video Bridging” is a set of six IEEE standards that was first published in 2011 contributing to enable synchronisation and reliable, high-priority delivery of audio and video over Ethernet.

However, this bundle of standards was not adequate in practice to achieve practical interoperability among the various developers and manufacturers.

MILAN

Milan has started in 2016 as a profile that guarantees interoperability of AVB audio devices in the market. It is a standards-based, user-driven deterministic network protocol for professional media, that assures devices will work together at new levels of convenience, reliability and functionality.
Milan has been created and is maintained by Pro Audio market leaders in the Avnu Alliance, and it is the first tangible solution for promising deterministic, reliable, and future-proof delivery of networked media.
Milan combines the technical benefits of the AVB standard with Pro AV market-defined device requirements at both the network and the application layer for media streams, formats, clocking and redundancy.

AVDECC Library

Avnu member, L-Acoustics (a French company and industry leader in the design, manufacturing, and distribution of premium sound reinforcement technologies) has published in 2019 an open source, free-to-use AVDECC Library that is now fully Milan compatible with the recently published Milan Discovery, Connection & Control Specification for Listeners & Talkers.
With this specification, Milan delivers a clear, defined profile for devices with a small subset of the standard and removes all ambiguities from this subset in order to achieve interoperability at the control layer.
The open source library offers a set of tools for controlling AVB and Milan devices using the AVDECC (IEEE1722.1) protocol and to meet Avnu Milan specifications.
These libraries can be implemented on Windows, Linux and macOS using standard development tools.
Unit tests and sample programs are also available.
The open source tools are available today on GitHub.

Avnu Alliance

“Reliable Synchronized Networking”

Avnu Alliance is a transformative force in the world of real-time networking.
Established in 2009 by experts from diverse fields such as networking, IT, professional media, and automotive, the Avnu Alliance goal has been clear and consistent: to promote and facilitate the rapid, widespread, and open industry adoption of standards-based networking for time-sensitive, highly reliable applications.

Avnu Alliance has built a robust Certification program, which is key to guarantee seamless interoperability of various products.

ALSE is now part of the Avnu Alliance as Milan Associate.
