— Telecom providers struggle with low service flexibility, increasing complexity and related costs. Although " cloud " has been an active field of research, there is currently little integration between the vast networking assets and data centres of telecom providers. UNIFY considers the entire network, from home networks up to data centre, as a " unified(More)
—Network Service Chaining (NSC) is a service deployment concept that promises increased flexibility and cost efficiency for future carrier networks. NSC has received considerable attention in the standardization and research communities lately. However, NSC is largely undefined in the peer-reviewed literature. In fact, a literature review reveals that the(More)
—Considering the increasing importance of carbon free networking solutions, several energy-efficient networking systems have been proposed and evaluated in literature. One significant challenge is how to encompass actions targeting energy savings and possible corresponding degradations in network QoS (Quality of Service). This paper presents an(More)
—Network service providers are facing challenges for deploying new services mainly due to the growing complexity of software architecture and development process. Moreover, the recent architectural innovation of network systems such as Network Function Virtualization (NFV), Software-defined Networking (SDN), and Cloud computing increases the development and(More)
