Automatic generation of network configuration in simulated time sensitive networking (TSN) applications

Abstract: The amount of data required to be processed in real-time embedded system is steadily increasing. This has caused industries to search for alternatives for reliable time-sensitive network communication. IEEE set of standards for Time-Sensitive Networking (TSN) is an attractive option for achieving this. It leverages the advantages of IEEE standards for Ethernet, such as high bandwidth and low hardware cost, while introducing deterministic behaviour. Simulation tools are used to facilitate verification and analysis of TSN networks. However, even simulation-assisted design of large complex networks is a challenging process. To alleviate this issue, this thesis investigates how TSN simulation can be improved by automatic generation of network configurations. So far, many different simulation frameworks have been developed in academia. This thesis builds on the OMNeT++ simulation framework and NeSTiNg simulation model. We prototype an automatic TSN configuration tool capable of generating configuration automatically through a graphical user interface (GUI). The purpose of the prototype is to demonstrate the feasibility of automatic configuration in TSN and how it eases design complexity. Furthermore, to verify the proposed tool a use case inspired by the vehicle industry is modelled. It is concluded that automatic configuration improves usability in five key areas, such as: (1) facilitating recollection of the network, (2) enabling automatic configuration, (3) increasing user-friendliness of a TSN simulation platform with a GUI, (4) increasing efficiency and usability of a TSN simulation platform, and (5) minimizing user error. The results gained in this thesis justify the usability of automation and could provide insights for future research and development of TSN simulation tools.
