Time Sensitive Networking is a proposed solution to the Quality of Service (QoS) requirements presented by delay sensitive traffic towards switched Ethernet networks. It is under constant development by the Institute of Electrical and Electronics Engineers (IEEE) to provide a wide range of tools which can support the existing Ethernet standards in fulfilling these QoS requirements. It is aimed at Consumer, Industrial, Automotive and Mobile Fronthaul solutions each of these fields having their own set of QoS requirements.

In my paper my goal is to provide an insight to some of these tools as and the overall role of TSN regarding mobile networks. To achieve this goal I introduce the reader to four of these mechanisms: Frame Preemption, Enhancements for Scheduled Traffic, Cyclic Queuing and Forwarding and Ingress Filtering and Policing. The standards focusing on these mechanisms were recently adopted or still are under active development by the TSN work group and are aimed at tackling the most pressing problems regarding delay sensitive traffic over Ethernet networks.

In my Thesis I introduce the reader to the mobile fronthaul and the Common Public Radio Interface (CPRI) protocol.

I select a simulation tool which can effectively implement these TSN mechanisms and with which I can demonstrate their use-cases and analyze their behavior to determine their potential in providing QoS in a Switched Ethernet network.
