RECAP (Reliable Capacity Provisioning and Enhanced Remediation for Distributed Cloud Applications): The Simulation Approach

In order to meet complexity, scalability and quality of service requirements in modern network infrastructures, resources need to be allocated and/or optimized along a Cloud-to-Thing (C2T) continuum using new paradigms. To accommodate the dynamism and address the variability, network operators and cloud systems will need to be able to pre-emptively take reconfiguration and remediation actions in a fully automatic fashion across the C2T continuum. In this work, we present the simulator approach in RECAP, an EU-funded research project, to develop the next generation of distributed cloud, edge and fog computing systems. Initial simulation experiments demonstrate that the RECAP Simulation Framework can run large-scale simulations of virtual content delivery networks and inform network optimisation decisions.
