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 admin@avnu.org, if you are a member and need to access something listed below.

Milan creates the endpoint solution layer for professional audio equipment based on the following AVB IEEE standards:

1. 1. IEEE 802.1BA-2011 – Audio Video Bridging
   2. IEEE 802.1Q-2014 –  Bridge and Bridged Networks
   3. IEEE 802.1AS-2011 – Timing and Synchronization for Time Sensitive Applications
   4. IEEE 1722-2016 – Transport Protocol for Time-Sensitive Applications in Bridged Local Area Networks
   5. IEEE 1722.1-2021 – Device Discovery, Connection Management, and Control Protocol for IEEE 1722(TM) Based Devices

Here is a peek at the High-Level Table of Contents for the Milan Specification Consolidated.

1. 1. Interoperability
   2. Discovery, Connection, and Control
   3. Base Stream Formats
   4. Media Clocking
   5. Seamless Network Redundancy

Automotive Ethernet AVB Functional and Interoperability Specification Revision 1.6

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.

802.1AS Recovered Clock Quality Testing Revision 1.0

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.

Avnu ProAV Bridge Specification Revision 1.0

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.

Test Plan for 802.1AS: Timing and Synchronization for Time-Sensitive Applications in Bridged Local Area Networks Version 1.0.1

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.
