Network Function Virtualization (NFV) technology is a key enabler in future mobile networks to achieve efficient Cloud-Radio Access Network (CRAN) platforms. Thanks to NFV, the core network software components can run in a virtualized environment - implemented by virtual machines (VMs) and/or containers - and make use of compute resources in a cost-effective way. Containerization of the application has gained increased popularity due to its smaller footprint when compared to VMs. A key functionality is the ability to live migrate containers along with their supported applications to a distinct server without causing service disruption.In this paper, we study the impact of a checkpoint-based approach for stateful container migration of the core network component SPGW (Serving /PDN Gateway) virtual functions, which handle both the control data with the MME (Mobility Management Entity) and the user data …
