[en] It has been more than 10 years since the inception of the Time-Sensitive Networking Task Group (TG) in IEEE802.1. Since then, TSN has become a rich toolbox of mechanisms and protocols to address Quality-of-Service (QoS) requirements pertaining to timing and reliability. While IEEE 802.1CB, AS and Qci are natural choices for dependability, the designer has much more possibilities when it comes to timing QoS. The selection and configuration of a suitable TSN scheduling solution is not straightforward, as many mechanisms are available (priorities, preemption, CBS, TAS, CQF, ATS), most of them being complex to configure, and they can be used in a combined manner to meet the needs of applications comprising mixed types of traffic.
In this talk, based on the academic literature and the observation of industrial practices, we review the well-understood and the emerging use-cases of the different timing QoS mechanisms and what we have learned in terms of their configuration. Ultimately, this talk aims at shedding new light on what to expect from TSN QoS mechanisms and how to introduce the least complexity needed to meet the application's timing requirements.
