Sensing and Stopping Interfering Secondary Users: Validation of an
We propose, implement, and test StopSec (Stoppable Secondary Use), a protocol that enables real-time detection and
Spectrum splitter user detection
Addressing these challenges, this paper introduces a Machine Learning (ML) based architecture for network operators to detect and attribute interferences to specific OSaaS users while blind to the users' internal spectrum details. With the growing demand for high-bandwidth, low-latency applications, Optical Spectrum as a Service (OSaaS) is of interest for flexible bandwidth allocation within Elastic Optical Networks (EONs) and Open Line Systems (OLS). While OSaaS facilitates transparent connectivity and resource sharing. We present the design and validation of Stoppable Secondary Use (StopSec), a privacy-preserving protocol with the capability to iden-tify a secondary user (SU) causing inter...
