Beskrivning av examensarbetet
Control applications in critical infrastructures need a reliable and robust communication system. For example, protection and control applications in power systems require reliable communica-tion networks that are fault-tolerant with zero-recovery delay. Furthermore, these communication networks need to provide time-synchronization to the attached end devices with an accuracy of below 1 us. To achieve zero-recovery delay and accurate time synchronization, the High-availability Seamless Redundancy HSR or the Parallel Redundancy Protocol PRP are com-monly used for substation networks in combination with the Precision Time Protocol PTP. These redundancy protocols, i.e. HSR/PRP, are based on Ethernet and are partly implemented as integrated circuits IC. Therefore, it is important to study the performance of different HSR/PRP implementations and benchmark the respective switch ICs. Moreover, Time-sensitive Networking TSN is expected to play an important role in future substation communication net-works. Thus, the performance of TSN switch ICs are evaluated as well as part of this thesis.

The scope of the thesis comprises the following main tasks:
1. Literature study on communication performance requirements for substation applications and on the corresponding IEC standards
2. Build up a test circuit to benchmark the different HSR-PRP switch ICs and TSN switch IC
3. Evaluate HSR/PRP and TSN performance
4. Evaluate PTP performance
5. Report on performance results of different switch ICs as well as on their compliance to respective IEC standards

Requirements:
To perform this master thesis successfully, the student should fulfil the following prerequisites:
• General embedded systems & software knowledge necessary
• Good programming skills in C and/or VHDL necessary
• Knowledge about communication networks recommended
