Ethernet TSN (Time-Sensitive Networking) has started profoundly reshaping automotive and industrial communications. TSN can be seen as a “toolbox” of 15+ protocols on top of Ethernet. In particular, TSN includes a growing set of Quality-of-Service (QoS) protocols such as IEEE802.1Qav (i.e., “Credit-Based Shaper”) and IEEE802.1Qbv (i.e., “Time-Aware Shaper”) that go well beyond the mere use of priorities (as offered by IEEE802.1Q).
If TSN opens up a wealth of possibilities for the network engineer to meet in an effective manner the diverse real-time and safety requirements of automotive and industrial communications, it also raises a number of questions:
- How to best use the TSN protocols? Especially, how to use them in a combined manner? How to configure their parameters in an optimized manner?
- What can we expect from the different TSN QoS protocols? What are the different technological, design and configurations alternatives?
How to design with evolutivity in mind and guarantee the amount of additional traffic the network will be able to support?

Prerequisites: the training is targeted at engineers with some prior knowledge of real-time communication (e.g, CAN network) and basic knowledge of Switched Ethernet network. This training does not assume any prior experience neither with TSN nor with modeling and perfomance evaluation tools.
To answers those questions, based on RTaW’s years of practical experiences in the design of TSN networks with leading OEMs in the automotive and aerospace and RTaW’s participation in the TSN standardization – RTaW staff is editor of a TSN standard (IEEE P802.1Qcw) and secretary of the aerospace profile standard (IEEE P802.DP), RTaW also participates in the activities of the automotive profile – we now offer a training on TSN with the following objectives:
Consolidate knowledge of TSN networking technologies and issues in using them. In particular, at the end of the training, participants will possess an understanding of:
- How a TSN switch operates,
- The TSN QoS protocols: IEEE802.1Q, IEEE802.1Qav, IEEE802.1Qbv, IEEE802.1Qcr, IEEE802.1Qbu, IEEE802.1CB, IEEE802.1Qci, etc,
- The use-cases for each them,
- The issues in configuring them and existing solutions,
- How to best deal with the limitations of the hardware (e.g., idle slope granularity for CBS, limited # of Gate Control List entries for CBS) ?
Allow participants to gain experience in modelling, designing and performance evaluation of TSN networks on a realistic case-study from their application domain,
- Through hands-on exercises with RTaW-Pegase modelling and simulation environment, understand the capabilities of tools like RTaW-Pegase and their limits.
