Demonstrating the advance of time-sensitive networking (TSN), Avnu Alliance has announced a new program that supports certification for devices according to the Institute of Electrical and Electronics Engineers (IEEE) SA’s 802.1.BA profile for audio/video bridging (AVB) as part of the IEEE TSN group of IEEE 802.1 standards. With this certification, network product manufacturers can ensure their devices comply with the core AVB/TSN standards that provide improved synchronization, low latency and reliability for switched Ethernet networks.
AVB and TSN standards enable precise timing within devices, allowing for the support of low-jitter media clocks and accurate synchronization of multiple steams so that different types of traffic seamlessly coexist on a single network.
However, interoperability and adherence to the IEEE’s SA’s AVB/TSN 802.1.BA profile are imperative for the successful deployment and management of these devices. In response, these tests have been rewritten to adopt a functional approach and primarily assess the switch’s performance within a functional system in addition to evaluating conformance with the IEEE specifications.
“The modifications implemented in the testing process will improve and speed up device certification, ensuring compliance with AVB/TSN standards and enhancing interoperability among platforms,” said Dave Cavalcanti, Avnu Alliance president.
Prominent system-on-chip manufacturers such as NXP Semiconductors, Analog Devices and Intel are actively supporting Avnu Alliance's Switch Certification Program.
