In the last few years, network "softwarization" is gaining increasing popularity to achieve dynamicity and flexibility. Cloud computing, as well as the new paradigms of Software Defined Networking (SDN) and Network Functions Virtualization (NFV), are supporting this evolution. However, the need to move services closer to users to guarantee low...

Beside increasing flexibility and programmability, the current network "softwarization" trend is believed to be beneficial also in respect of energy efficiency, owing to the consolidation of resources made possible by virtualized networking components. However, the widespread use of general-purpose hardware may jeopardize energy saving, unless...

The Fifth generation(5G) technology moves a step forward from the previous generations by natively supporting vertical applications with real time and low latency requirements. However, the resultant increase of computing resources will cause a consequent increase in the energy requirement and an impact on the carbon footprint. To this end, it...

We consider multiple bursty flows characterized by different statistical parameters and performance requirements, which generate packets that require some form of processing at the network edge. We model the processing resources as multiple servers that can be activated/deactivated on a longer time scale with respect to the packet dynamics....

In order to fulfill the stringent requirements of 5G applications, measuring the performance of the VNFs composing the network slices is crucial to identify potential bottlenecks of the networks. However, since the VNF behavior is time varying and strongly depends on the infrastructure and hosting execution environment, the traditional traffic...

In order to fulfill the stringent requirements and fast advancements of 5G and beyond applications, it is inevitable to develop research/industrial testbeds to examine the different proposed innovative features of 5G and beyond. In this paper, we propose a testbed including 5G and beyond technologies by combining open-source solutions and our...
