NFV/SDN-based vEPC solution in hybrid clouds

Network Function Virtualization (NFV) is an emerging key technology to overcome the major challenges facing the mobile network operators such as reducing the capital and the operating expenses, and satisfying the growing demand for mobile services. NFV was introduced by mobile network operators as a promising solution to transfer the IT virtualization technology advantages to the telecommunication industry. This paper proposes a novel NFV/SDN-based solution that allows the migration of the mobile core network to the cloud with a fine-grained QoS while maintaining the scalability of the virtualized network function entities. Additionally, the proposed solution facilitates the co-existence of virtualized network function instances and IT could applications in a multi-tenant private and public cloud architecture.
