Virtual Evolved Packet Core (vEPC):

The vEPC use case exhibits and assesses the SONATA system’s capacity to enhance a virtual EPC service in a LTE mobile network. It’s a true NFV telco operator use case, as it represents the big challenges that come with the transition from managing physical to virtualized networks.

The use case addresses a Mobile Virtual Network Operator (MVNO) wishing to operate their vEPC as a network slice on top of a virtualized infrastructure (NFVI provider) in order to gain greater flexibility. This enables the MVNO to continuously dimension the service and functions of the end-user’s activity, optimization of placement with regards to user’s location, increase resiliency by optimally adapting the system to failure or security attack, and to exploit a new maintenance workflow using DevOps principles.
