Ethernet TSN (Time-Sensitive Networking) is 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 traffic class priorities and VLANs.

If TSN opens up a wealth of possibilities 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? Download this presentation for some insights into these questions.
  • What can we expect from the different TSN QoS protocols? What are the different technological, design and configurations alternatives?

  • How to map SOME/IP and DDS services to TSN QoS mechanisms?

  • 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.

The training can be facilitated either as 8 sessions of 3 hours over Webex, or a your office location over 3 days.

Detailed training content and samples of training material available upon request, please contact us.
This training can be given in English, German, French, Italian or Chinese

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 was editor of a TSN standard (IEEE P802.1Qcw) and secretary of the aerospace profile standard (IEEE P802.DP) – 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)?
    • How to model and verify a Service-Oriented Architecture relying on SOME/IP or DDS?
    • How to verify end-to-end timing chains (i.e., sensors to actuators) considering the OS and scheduling of tasks?

  • 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.
