The evolution of professional audio networking has increased the demand for high-quality, interoperable, and efficiently managed networks. AES67, a standard for high-performance audio over IP, leverages ubiquitous IP infrastructure for scalability and flexibility. But in its current form, it lacks efficient ways to control the networks delivery behaviour, while AVB provides robust Layer 2 delivery guarantees but is limited by Layer 2 constraints. This paper investigates the use of Time-Sensitive Networking (TSN) protocols, particularly from Audio Video Bridging (AVB), to support AES67 audio transport. Integrating TSN protocols with AES67 achieves AVB`s QoS guarantees in a Layer 3 environment. IEEE 1588 Level 3 PTP Media Profile ensures precise synchronization, packet scheduling reduces latency and jitter, and bandwidth reservation prevents congestion. Experiments show that TSN protocols enable AES67 to achieve latency, jitter and packet loss performance on par with AVB, providing reliable audio transmission suitable for professional applications in modern, scalable networks.
