Abstract (technical / expert description):

This research project
deals with the application of quality of service guarantees in Time-Sensitive Networking,
in particular using Network Calculus. Real-time systems are increasingly
required in industry, e.g. the automotive, automation or entertainment
industries. Classical Ethernet, however, does not guarantee real-time performance,
which leads the Time-Sensitive Networking Task Group (IEEE 802.1) to develop
standards for real-time data transmission over Ethernet networks. These
standards are summarized under the term Time-Sensitive Networking (TSN). Within
the scope of this research project, the application of Network Calculus for TSN
is now being investigated. Network Calculus (NC) is a system theory for
deterministic performance evaluation. It uses mathematical methods to provide
performance guarantees for communication systems. NC can help evaluate TSN's
real-time properties, meet required latency limits, and provide insight into
the optimal configuration of networks. It also enables buffer sizing and can
evaluate existing or new scheduling algorithms.
