TSN - Future Industrial Ethernet Standard or AVB 2.0? Vortragssprache Englisch

Over the last decades Ethernet has become the de facto standard for high-bandwidth standardized communication between computing devices. Originally invented for Local Area Networks it has been adapted for many other use cases, like VoiP communication or audio video bridging (AVB). Ethernet is standardized, exists everywhere and is one of the most cost-efficient ways to connect a huge number of communicating devices. However, when it comes to industrial control applications, additional requirements, such as determinism, redundancy and short latencies arise. These requirements, so far were addressed by industrial Ethernet protocols, such as EtherCAT or ProfiNET. With the upcoming and now mostly finalized IEEE 802.1 TSN standard, this is about to change. Having evolved from the existing 1722.1 AVB standard, it adds capabilities such as frame preemption and seamless redundancy to also live up to abovementioned industrial requirements. Being an open standard and driven by both the automotive and industrial world, TSN is destined for the next big step in industrial Ethernet communication. In this paper we take a closer look at TSN from an industrial automation viewpoint and discuss different use-cases that could be enabled by this new standard. We then discuss the various IEEE 802.1 sub-standards and their respective significance for these use-cases. Wherever hardware or reliable simulation data is available, we create test cases and scenarios to analyze atomic TSN features and their advantages and disadvantages over traditional industrial Ethernet protocols. We will also discuss the feasibility of TSN to replace traditional industrial Ethernet protocols in these scenarios.
