A proposal to integrate process data communication to IEEE 802.1 Audio Video Bridging (AVB)

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.
