Analyzing Interaction Between CCAs and Traffic Policers

Collection of recent networking and systems research with several operational-security implications: a 3GPP-aligned GNSS spoofing detection and monitoring framework for TDD networks (high detection rates in simulation, integrates with existing SA5/SA3 management structures); experimental characterization of NVIDIA ConnectX-7 Accurate Scheduling and hardware timestamping showing ~±7–8 ns timestamp variation and ~99% of scheduled transmits within ±900 ns (occasional ~5 µs outliers), relevant to 5G fronthaul vs. TSN determinism; a formal framework for interaction between congestion control (CCAs)
