“…Since the concept of RFB is not constrained to a given operating system, platform‐agnostic languages and tools are needed to describe the interactions and connections between the RFBs and the execution environments on which the RFB can be deployed. We refer the reader to Bianchi et al for a detailed overview of these features.…”

“…Moreover, other possible implementation of RFBs can be modules and components of special purpose execution environments, like extended finite state machines based on OpenFlow for packet processing, software routers, or radio signal processing chains . In this way, the management of the network through a set of RFBs introduces the levels of flexibility and agility, which are required for a full exploitation of the predicted 5G services …”

“…Among the different projects currently investigating 5G architectures, it is worthwhile to mention SUPERFLUIDITY, which is funded by the EU through the H2020 program. The goal of SUPERFLUIDITY is to design a new 5G network architecture, which ensures the required levels of flexibility, agility, portability, and high performance.…”

“…In particular, RFBs can be arbitrarily decomposed in other RFBs, while VNFs in the ETSI model cannot be composed in other VNFs. Moreover, the RFBs can be mapped into different software (SW) and HW execution environments (see Bianchi et al), while the ETSI model focuses on mapping VNFs into virtual machines (VMs; or containers) in traditional cloud infrastructures.…”

Summary We consider the problem of managing a 5G network composed of virtualized entities, called reusable functional blocks (RFBs), as proposed by the Horizon 2020 SUPERFLUIDITY project. The RFBs are used to decompose network functions and services and are deployed on top of physical nodes, in order to realize the 5G functionalities. After formally modeling the RFBs in a 5G network, as well as the physical nodes hosting them, we formulate the problem of managing the 5G network through the RFBs, in order to satisfy different key performance indicators to users. In particular, we focus either on the maximization of the amount of downlink throughput sent to users or on the minimization of the number of powered‐on physical nodes. We then consider different scenarios to evaluate the proposed formulations. Our results show that, when an RFB‐based approach is put into place, a high level of flexibility and dynamicity is achieved. In particular, the RFBs can be shared, moved, and rearranged based on the network conditions. As a result, the downlink throughput can be extremely high, ie, more than 150 Mbps per user on average when the throughput maximization is pursued and more than 100 Mbps on average when the goal is the minimization of the number of powered‐on physical nodes.

The architecture proposed in [13] follows the Superfluid NFV approach considering the decomposition of services into smaller reusable components and the highly dynamic instantiation of virtualized resources.

Network operators are facing significant challenges meeting the demand for more bandwidth, agile infrastructures, innovative services, while keeping costs low. Network Functions Virtualization (NFV) and Cloud Computing are emerging as key trends of 5G network architectures, providing flexibility, fast instantiation times, support of Commercial Off The Shelf hardware and significant cost savings. NFV leverages Cloud Computing principles to move the data-plane network functions from expensive, closed and proprietary hardware to the so-called Virtual Network Functions (VNFs). In this paper we deal with the management of virtual computing resources (Unikernels) for the execution of VNFs. This functionality is performed by the Virtual Infrastructure Manager (VIM) in the NFV MANagement and Orchestration (MANO) reference architecture. We discuss the instantiation process of virtual resources and propose a generic reference model, starting from the analysis of three open source VIMs, namely OpenStack, Nomad and OpenVIM. We improve the aforementioned VIMs introducing the support for special-purpose Unikernels and aiming at reducing the duration of the instantiation process. We evaluate some performance aspects of the VIMs, considering both stock and tuned versions. The VIM extensions and performance evaluation tools are available under a liberal open source licence.

Mobile communication is on the brink of another transformation as fifth generation networks and their architectures are already mature for deployment. As the volume and intensity of data flow drastically increases, the technologies that fuel such changes need to be evolved. Mobile small cells are going to play a key role in the deployment of these new communication infrastructures, extending the reach of wireless access. In this paper a number of path loss models for and indoors office environment are simulated using Mininet-WiFi. The channel characterization is based on a set of parameters including RSSI, SINR, latency, throughput, etc. The preliminary results indicate that ITU and multi walls multi floors models are accurate enough to be used as a basis for an intelligent, cloud based radio resource management of heterogeneous wireless mobile small cells.
