Per-user NFV services with mobility support

This paper presents an architecture to provide end-to-end per-user services with support to client mobility, designed according to the SDN and NFV paradigms. Our service platform dynamically configures and launches service requests when the client connects to the network, which are used by a multi-domain orchestration system to arrange the required network configuration and computational resources. Service configuration is dynamically updated when a movement of the client is detected, that is, when a client device changes its access point to the network. A prototype implementing the idea has been developed and validated over JOLNET, a real, geographical, OpenFlow-based experimental network connecting several sites in Italy and operated by Telecom Italia.
