Time-critical cyber-physical applications demand the timely delivery of information. In this work, we employ a high-speed packet processing testbed to quantitatively analyze a packet forwarding application running on a shared memory multi-processor architecture, where efficient synchronization of concurrent access to a Forwarding Information Base is essential for low-latency and timely delivery of information. While modern packet processing frameworks are optimized for maximum packet throughput, their ability to support timely delivery remains an open question. Here we focus on the age of information performance issues induced by throughput-focused packet processing frameworks. Our results underscore the importance of careful selection of offered load parameters and concurrency constructs in such frameworks.
