    Performance Evaluation of IEEE 802.1Q Time-Sensitive Networking Transmission Selection Algorithms (ATS Performance)

    Partner Siemens Predevelopment Nürnberg
    Funded period Since June 2018
    Researcher Dr. Florian Metzger
    Alexej Grigorjew M. Sc.

    Project Description

    The IEEE standard 802.1Q is under further development, and the Time-Sensitive Networking (TSN) working group is regularly extending the specification in order to enhance predictable data transmission via Ethernet in LANs. In the project “ATS-Performance”, the Chair of Communication Networks of the University of Würzburg and SIEMENS Predevelopment Nürnberg investigate performance characteristics of various such extensions with a special focus on novel Transmission Selection Algorithms for time-critical traffic. These evaluations are mainly based on formal investigations and simulation.
