TSN Reservation Framework for Legacy Apps - Signaling, Shaping, Monitoring, and Measuring
Alexej Grigorjew, Tobias Hoßfeld, David Hock, Fabian Lipp · 2025
This demo presents a framework that enables predictable real-time guarantees for legacy TCP applications over Ethernet. It includes four components: (i) a lightweight signaling system that implements a simplified TSN Resource Allocation Protocol with minimal dependencies, (ii) a proxy that terminates TCP connections locally, initializes resource reservations, and enforces the traffic specification through shaping, (iii) a monitoring system that tracks overall network utilization and status, and (iv) an accurate live measurement and visualization of one-way delays for all reserved streams. The components are focused on simplicity to facilitate deployment and encourage innovations.
