QoS – Application of TSN to EtherNet/IP Networks

Technical Paper Abstract
Deterministic Ethernet is already widely used in industrial control systems. Many Industrial protocols solve the problem of determinism over Ethernet using proprietary layer 2 solutions. The new IEEE 802.1 TSN standards are aimed at the same class of problems encountered in industrial control and promise to supplant proprietary solutions in favor of a standards-based approach. EtherNet/IP has always relied upon standard, commercially available Ethernet technologies to deliver deterministic performance and is therefore well-positioned to leverage these emerging standards.

In this paper we discuss specific use cases and examine how the emerging TSN standards can be applied to EtherNet/IP networks to provide improved determinism and performance. We will also contrast the results expected in a TSN-based network with those of the technologies currently in use.
