This paper investigates prospects of the emerging IEEE 802.1 Audio Video Bridging (AVB) Ethernet standard in industrial automation applications. The notion of a small and predictable latency is common for both industrial and multimedia (audio, video) applications. The inbuilt characteristics of 802.1 AVB that includes synchronization, real-time traffic scheduling & shaping and resource reservation makes it a real-time capable Ethernet solution, which can be used for the process control applications as well. This paper presents a way to integrate the industrial process data communication to the lower layer services of IEEE 802.1 AVB, and describes a demonstrator implemented for a proof of concept.
