In currently deployed networks the time critical and/or real time traffic is sent over dedicated networks, requiring the operation of a separate infrastructure. That is especially true for Industrial Networks, which use such technologies and protocols that are designed particularly for that purpose. The IEEE 802.1Q Time-Sensitive Networking (TSN) workgroup took a huge step in that direction with their standardized solutions, so that Ethernet networks could reach precise timing and defined QoS mechanisms for that. The question is, are these TSN mechanisms viable solutions instead of the protocols that are used in industrial environments.

In this Thesis I review the currently deployed typical industrial network technologies and protocols and the 802.1Q Ethernet TSN mechanisms. With the help of the literature I selected such network switched Ethernet network set-ups, that represent the industrial networks well. In the OMNeT++ simulation tool I implemented the networking topologies and the traffic models. I investigated with means of simulation the possibility to replace the industrial protocols with TSN and investigated the fulfillment of the required QoS levels.
