The Age of Information (AoI) metric measures the freshness of status updates for monitoring and feedback in networked systems. It has received significant research interest due to its relevance in Internet of Things (IoT) and Cyber-Physical Systems (CPS). However, its analysis is largely open for parallel systems despite of their relevance in multi-band mobile networks, multi-technology wireless access, or multi-path protocols. In this talk, I will discuss some insightful results for AoI in parallel systems that we obtained using effective bandwidth and stochastic network calculus. A key question we will address is, when does a parallel-server system has lower AoI than a single-server system with equivalent capacity?
