Avnu Alliance has been developing conformance specifications and test plans across various markets based on market accepted requirements of Time Sensitive Networking, since 2009. Please reach out to firstname.lastname@example.org, if you are a member and need to access something listed below
Avnu Alliance Test Plans and Specifications
Milan creates the endpoint solution layer for professional audio equipment based on the following AVB IEEE standards:
- IEEE 802.1BA-2011
- IEEE 802.1Q-2011
- IEEE 802.1AS-2011
- IEEE 1722-2016
- IEEE 1722.1-2013
Therefore, Milan defines a set of technical profiles for these IEEE standards dedicated to professional audio endpoints:
This document specifies a concise set of requirements upon the various AVB standards and Milan professional audio endpoints.
Milan defines stream format profiles for professional audio devices based on the IEEE 1722-2016 Standard AAF Audio Format. The advantage of AAF is that it is less complex and more efficient than AM824.
There are a number of methods that can be used for synchronizing media clocks on a local area network (LAN). This document defines the Milan required method for providing interoperable and certified media clock synchronization for Pro Audio devices.
Milan redundancy works to give ProA AVB devices the ability to endure against a number of network failures.
This document describes the Avnu required method for providing interoperability and certified discovery, connection, and control mechanisms for Professional Audio AVB devices. This specification relies on a disambiguated subset of the IEEE 1722.1-2013 standard in order to achieve interoperability between Professional Audio devices and controllers.
This corrigendum provides technical and editorial corrections to the “Discovery, Connection and Control Specification for Talkers and Listeners, v1.1a” document published by Avnu Alliance on January 22, 2019.
This document is Avnu’s interoperability and functional specification for automotive Ethernet AVB devices. The document’s primary goal is to provide a baseline specification of Ethernet AVB functionality on automotive AVB devices. The specification has several uses, three of which are key. First, vendors can use this specification to guide their automotive AVB product development. Second, Avnu can use it to develop an effective certification process. Third, and most importantly, automotive OEMs can depend on the specification to provide a foundation for AVB functionality in their automobiles. OEMs can be assured that a device certified to be compliant with this specification would provide baseline AVB functionality, would not require extensive testing on their part, and would thereby allow them the time to focus on other functionality that helps differentiate their final product and enable success in the automotive marketplace.
The Generalized Precision Time Protocol (gPTP) provides an accurate time base to all time aware elements in an Ethernet network. Applications such as Audio/Video and Automotive/Industrial Control rely on the time provided by this protocol for synchronization of events. This specification defines methods to measure gPTP recovered clock quality for Avnu certification.
This specification is an advancement from the former ‘Pro AV Endpoint and Bridge AVB/TSN Functional and Interoperability Specification Rev 1.1’ issued in February 2018. It introduces a specification for ProAV Bridges that is independent from legacy ProAV and Milan Endpoint specifications and adds relevant clarification to so far undefined or ambiguous details.
This document is intended to be representative of the scope and format of a Avnu test plan. Included is a complete Table of Contents of every test case. The last test case is unabridged to convey the level of detail represented in Avnu’s test plans.
