Thesis Work - Experimenting with frame replication and elimination for reliability

Thesis Worker at Volvo Cars


Welcome to explore the world of Volvo Cars by authoring your thesis with us! As a thesis worker in our organization, you are supported by a supervisor who follows you during your project. All thesis projects are arranged in business-critical areas and therefore you will be able to contribute to our company's purpose – providing freedom to move in a safe, sustainable, and personal way – from day one!  




Automotive companies deal increasingly with time sensitive networks (TSN) that involve safety functions. TSN do not have time redundancy on layer 2, and thus a strategy is needed to tolerate temporary faults.


For safety-critical applications, reliability is an important feature for safety relevant data delivered from source to destination. A delay of an ethernet frame containing safety-relevant data could have adverse effects on the vehicle's safety. Faults in any parts of the system must be reported timely and reliably since they can otherwise cause hazardous side effects.


A mechanism to tolerate such faults was defined as part of IEEE 802.1CB-2017 standard called FRER (Frame replication and elimination for reliability). FRER adds fault-tolerance by sending the same frames via redundant paths. Although its core functions are defined by the standard, its efficacy depends on the actual deployment scenario and the path selection strategy. Different topologies may affect reliability and overall network resilience differently and are part of what we are interested in investigating.




As part of this thesis, we want to develop a simulation model that reflects different vehicle ethernet topologies running some standardized traffic flows and generate faults on these topologies. Using this simulation model, together with the fault model, we want to understand how the overall communication reliability, uptime, and performance is impacted by utilizing FRER.


We want to do so by using modern open-source network simulators such as OMNeT++ or ns3.


Relevant technical domains: System verification and validation, system safety, system network topology design and optimizations, system reliability, networking systems, modelling real systems, fault modelling
