An enabling technology for the fifth generation (5G) ofwireless communications is the virtualisation of network resources. 5G networks are expected to consist of dense deployments and efficient resource allocation is a top priority. At present, there is a growing number of research projects, investigating network virtualisation at different levels. The virtualisation of core network functionalities is the topic of the T-NOVA project where a virtualised cloud infrastructure is responsible to provide them, thus achieving elasticity and flexibility in network deployment. Moreover, various tools such as OpenFlow have been developed allowing the dynamic and scalable adaptation of the core network regarding the routing of data. Also, open-source solutions such as OpenStack have been adopted for the management of public and private clouds as well as the well-timed creation and effective maintenance of virtual machines.
