Deterministic, low-latency and reliable communication of time-sensitive data is a critical challenge in industrial and automotive networks. IEEE introduced the Ethernet standards Time-Sensitive Networking (TSN) to address these requirements. Besides traffic prioritization and scheduling, TSN supports the Frame Replication and Elimination for Reliability (FRER) mechanism to transmit packets via redundant paths in a parallel way. Industry 4.0 has intensified the need for mobility, such as using Automated Guided Vehicles (AGVs). To meet these demands, 5G must be integrated into the TSN system. To support end-to-end redundancy compensating varying channel qualities and packet loss, FRER shall be integrated into the TSN+5G network.

Goal of this Research Internship (Forschungspraxis) is the implementation of FRER in the OMNeT++ simulator using the frameworks inet and simu5g. Based on the implementation, different scenarios shall be simulated and analyzed considering varying topologies and traffic scenarios.

Prerequisites

Deterministic, low-latency communication for time-sensitive data is a critical challenge in industrial and automotive networks. IEEE introduced the Ethernet standards Time-Sensitive Networking (TSN) to address these requirements. Using traffic prioritization and scheduling, TSN enables deterministic, reliable, and low-latency communication. However, industry 4.0 has intensified the need for mobility, such as using Automated Guided Vehicles (AGVs). To meet these demands, 5G must be integrated into TSN systems.

Your role will involve enhancing and further developing a TSN-5G testbed. A baseline testbed integrating 5G into TSN is already in place. The next phase of development focuses on integrating reliability mechanisms. Your specific tasks will include:

• Measuring and analyzing end-to-end delays.
• Setting up and integrating additional devices, such as UEs, into the testbed.
• Integrating a network controller into the system.
• Adapting the controller to support additional mechanisms.

What you’ll gain:

• Experience with networking hardware.
• Expertise in hardware measurements.
• Practical experience in system implementation.

Depending on your availability, your working hours per week can be between 10 and 20. If this opportunity interests you, please send us a brief introduction about yourself along with your CV and transcript of records. We look forward to meeting you!
