Automated and Precise Deterministic NetCal Calculations from Models to Bounds Pesotsky, Wlad Hermsen, Eric Bondorf, Steffen Network Calculus Real-Time Systems The deterministic variant of Network Calculus (NetCal, NC) enables for calculating worst-case performance guarantees in communication networks. We present the NetworkCalculus.org Deterministic Network Calculator (NCorg DNC), a tool for Deterministic Network Calculus (DNC) that extends the previous DiscoDNC by significantly enhancing its capabilities for modeling and analysis of real-world applications. The tool offers a new end-to-end solution: Starting from the prevalent model of a full-duplex Ethernet-like networks with output queueing, the NCorg DNC offers automated conversion to its DNC model as well as application of state-of-the-research DNC analysis methods to derive worst-case delay bounds. Another significant step forward are new numerical capabilities that can model and analyze, among others, discrete data arrivals as well as service. While we enhance features and capabilities, we keep the cost in terms of tool runtimes at bay. Our numerical evaluation showcases improved performance bounding w.r.t to previous DiscoDNC results and a comparative experimental tool performance study quantifying the computational impact of the added functionality. Overall, the NCorgDNC provides a more versatile and extensible foundation for deterministic performance analysis in modern networked systems.
