Back to the Future: Hardware-specialized Cloud Networking


In the last decade, the networking research community has significantly fueled the network softwarization and virtualization trend. Network processing tasks, originally performed by dedicated hardware appliances, were converted into software components running on commodity hardware, and deployed in relevant cloud infrastructures (central and/or edge). While this trend is clearly a winning proposition in terms of cost and flexibility, non-marginal concerns do emerge not only when considering performance and energy consumption, but also when addressing horizontal scaling limitations currently affecting edge cloud deployments. As a matter of fact, emerging media-rich and network-intensive applications come along with throughput and latency requirements which may be overly challenging for software functions. And the ever stronger network security requirements (with their relevant security-oriented network processing overhead), further play havoc with the performance limits of softwarized functions. The thesis of our talk is that cost and flexibility is NOT necessarily in contrast with performance and power consumption! We support our thesis by making a case for domain-specific architectures for efficient and high-speed packet processing. We will specifically discuss the tailored design of fully programmable hardware platforms specialized for networking and for packet processing, and how they can attain very significant performance gains with respect to their software counterparts meant to be deployed on commodity CPUs.

Empowering Internet of Things in Space though virtualization and federation of CubeSat constellations


In recent times, the attention of the IoT scientific community on a class of miniaturized satellites called CubeSats has significantly increased, and these devices are proposed as a particularly effective solution for offering IoT services even in remote areas of the globe. Building on this growing interest, this speech will present an approach to integrating CubeSat constellations into IoT platforms running within next-generation terrestrial-satellite infrastructures leveraging SDN/NFV technologies. In this scenario, the potential of a game-changing cooperative paradigm based on federation between the Virtualized CubeSat (ViCube) constellations and their orchestration in terrestrial Edge nodes will be analyzed. Possible scenarios will be presented that allow greater flexibility and effectiveness in the provision of pervasive IoT services, the potential of the paradigm will be highlighted, and possible research directions that this paradigm reveals will be indicated.

Toward Fully Programmable and Virtualized Wireless Networks for 5G and Beyond


This talk will present an overview of our work on laying the basic design principles for new approaches to programmable and virtualized next-generation wireless networks. We will cover three four research thrusts, namely architectures, programmability, slicing, and experimental testbeds. First, we will introduce the building principles of end-to-end fully virtualized cellular wireless networks, and discuss architectural alternatives and options. We will also discuss the main recent developments within the leading open-source alliances. Then, we will talk about programmability, or how to develop abstractions and algorithms to automatically control resources in an end-to-end environment. In this context, we will discuss our prior work on developing CellOS, a new Cellular Operating System. The third part of the talk will focus on the role of network slicing, and on recently developed algorithmic and architectural frameworks to provide optimally sized, isolated slices on virtualized infrastructures with differentiated SLAs in terms of performance and security. Last, we will discuss the state of the art of the experimental testing ecosystem for 5G and beyond, focusing on advances in the Platforms for Advanced Wireless Research Program, and discuss the role of open testing platforms in advancing the wireless ecosystem.

Internet of Things: towards the development of a smart yet secure world


The Internet of Things (IoT) revolution is turning everyday objects into smart ones. Such smart things are able to interact among themselves and with the environment they are placed in order to fulfill a given goal. As a result, a global network infrastructure is being created, supporting the provisioning of innovative and customized services to individuals and businesses in different application domains. The resulting system may include an extremely large number of heterogeneous devices, moving up integration and scalability challenges to be addressed. Moreover, the increasing diffusion of IoT enabled services raises several risks associated to security and privacy, which include: data confidentiality and authentication, access control, trust among users and smart things, and policy enforcement. Traditional security countermeasures cannot be directly applied to IoT technologies due to the different standards and communication stacks involved.

The talk focuses on the security challenges arising in IoT enviroments, where the notion of interconnected smart objects has a primary role. To cope with the emerged issues, a flexible and cross-domain middleware platform must be set up with the final goal of managing the huge amount of IoT data and promptly dealing with security threats in the IoT dynamic environment. New challenges, related to the strictly resource constraints and limited dimension of the devices, are further presented by the revolutionary Internet of Nano-Things (IoNT) concept, which goes beyond the already diffused “smart things” towards real application of “smart nano-things”. The talk discusses more broadly how security solutions can contribute to the design and develop robust IoT and IoNT neworks, and suggests exciting open areas for future research
