In 2009, he achieved II-level master on “Homeland Security” at the University of Bologna.

He teaches “Broadcast and Multimedia technologies”, “Security of Internet infrastructures” and “Fundamentals of Computing” at the University of Rome “Tor Vergata”. He is involved in national and international research projects in the ICT  field, playing the role of technical and project manager. Finally, he is co-author of more than 110 indexed scientific publications. 

Title:  "NTN Softwarization and Virtualization o for the integration in 5G " 

Abstract:  "The current shift toward the virtualization of network infrastructure components enables a dynamic instantiation, deployment and configuration of virtual network functions (VNFs), which can be offered “as-a-service” to multiple tenants, thus enabling 5G architectures. Simultaneously, the recent satellite systems can play an important role in the 5G era thanks to their characteristics, such as their large coverage, fast deployment of the ground infrastructure and native broadcast/multicast broadband capabilities.

An actual and effective integration between 5G and satellite requires to solve the mismatch in technology and design principles, which has made satellite-terrestrial convergence quite challenging over the years, with the satellite role limited to either provider of raw supplementary capacity or a gap-filler in the terrestrial networks. For instance, the use of SatCom for IP based applications typically requires the introduction of middlebox agents for performance optimization, and then technological barriers for integration. 5G intertia towards specifications softwarization and service-based architectures makes possible a cutting-edge for the integration of the satellite, as a software-based virtual service. This allows to review the role of satellite from a “technology to integrate” to an “application to deploy”. This transformation is the main subject of the presentation, considering some reference use-cases coming from ESA-funded research activities. ".
