An evaluation of software-based TSN traffic shapers using Linux tc

In this study, the feasibility of a hardware abstracted switch that targets TSN applications is evaluated. A solution using P4, a flexible solution to program SDN switches, is discussed. Nevertheless, extensions to this approximation have to be made to respect time oriented features that are unavailable to implement in a sole P4 environment. As a consequence, the Linux tc package is used to program the traffic control functionalities such as TAS and CBS shapers. The final implementation is a proof of concept that uses tc and runs on top of the Linux kernel. Finally, future work is discussed as a possible followup to this project.
