Network Softwarization Coming of Age: New Challenges and Opportunities
Enterprise networking services are increasingly moving to the cloud, network automation and gaining operational insights are top-of-mind for network providers, and new services demand stringent service-level guarantees are emerging. All of this is happening while the number of interconnected entities, the volume of traffic, and the dependence of our society on networking services continue to grow unabatedly.
These trends require management technology to go beyond keeping pace – the bar to enable the seamless operation of modern networks. Networks must be softwarized to meet current demands – to roll out and deploy new services, avoid disruptions, protect against abuse, and improve networking economics.
What are the implications on the network softwarization field, and what specific opportunities and challenges are ahead of us?
This panel will explore those opportunities and challenges that are expected to arise. The panel will be structured along the following statements, each allowing exploration of a distinctive aspect:
- The next step in network softwarization is replacing the control plane with some form of AI.
- Network softwarization leads to a naïve reliance on automated tools (including AI/ML systems); there will eventually be some backlash towards integrated hardware.
- Low-latency services need special attention in sofwarized networks.
- Softwarized networks require special management of security and privacy.

Dr. Barbara Martini is a Professor at Universitas Mercatorum in Software Engineering (ING-INF/05), Italy since January 2022 and Affiliate Researcher with Scuola Superiore Sant’Anna, Italy, since 2003. After her Master Degree at University of Florence in Electronic Engineer, she worked as software designer, developer and product integrator for two large telco companies, Italtel and Marconi Communications (currently, Ericsson), from 1999 to 2003. She was with the Italian University Consortium for Telecommunication (CNIT) from 2003 to 2022 with leading roles from 2009, coordinating research activities in the field of network virtualization and orchestration in 5G, network control/management architectures and programmability, service platforms for networking, and security solutions for multi-domain networks and NFV deployments. The research is carried out in several application scenarios, from Logistics, Genomics to E-health, to name a few. Prof. Barbara Martini co-authored over 100 papers in top-notch scientific journals and international conference proceedings.
She has been involved in several national/EU research projects, the recent ones 5GPPP 5GEx, 5GTRANSFORMER, 5GROWTH in 5G/SDN/NFV, ICONET in Physical Internet for Logistics, and in several FIRE projects (OFELIA, Fed4FIRE+, TRIANGLE, 5GINFIRE) with leading roles.
Her experience spent in both academic institutions and large industrial companies gave her the opportunity to acquire a deep technical knowledge and at the same time a broad view over the subject and to foster an effective synergies between the major ICT companies and the most representative Research Centers in telecommunications that was essential to pursue innovative research results as well as to maximize the impact of my research in terms of technology developments and applications.
Dr. Paolo Crosta joined Italtel in 1996, where he had the opportunity to gain, with different roles and increasing responsibilities, valuable experience in technical, management and financial areas.
Today, he manages the entire R&I process of the Company, from public incentives until market innovation, passing through partner networking, concept generation, project management, prototyping, up to dissemination and exploitation.
Dr. Paolo Crosta started leading his first R&D team in 2004. In 2012 he started his journey in the international arena of R&I, revitalizing Italtel’s activities in collaborative R&I projects in Italy and in Europe, expanding Italtel’s R&I ecosystem. In 2017, he was appointed responsible also for the financial aspects of R&I projects.
Dr. Paolo Crosta built extensive expertise on various ICT topics, starting from Cloud Computing, Next Generation Networks (5G/6G, Edge Computing) and network softwarization technologies (NFV, SDN), passing through High Performance Computer and Internet-of-Things (IoT), up to Big Data, Artificial Intelligence and Cybersecurity.
His interests are focused on the following market sectors: Telecommunications, Industry 4.0, Smart City, Healthcare, Transportation, Energy and Cybersecurity.
Jeff Tantsura has been in the networking space for 25+ years and has authored/contributed to many RFC’s and patents, worked in both, SP and vendor environments. He is co-chair of IETF Routing Working Group, chartered to work on New Network Architectures and Technologies, including protocol independent YANG models and Next Gen Routing Protocols as well as co-chair of RIFT (Routing in Fat Trees) Working Group chartered to work on the new routing protocol that specifically addresses Fat Tree topologies typically seen in the Data Center environment. Currently, Jeff is Sr. Principal Network Architect Azure Networking at Microsoft, working on the Next Gen DC architectures and ML/AI networking.
Diogo Menezes Ferrazani Mattos is a professor at the Department of Telecommunications Engineering in the Universidade Federal Fluminense (UFF), Niterói, Brazil. He holds a doctorate in Electrical Engineering from the Universidade Federal Rio do Janeiro (COPPE / UFRJ), 2017. Between 2015 and 2016, he was a sandwich doctoral fellow at the Laboratoire d’Informatique de Paris 6 (LIP6) at the Université Sorbonne, campus Pierre et Marie Curie, Paris, France. He completed his Master’s Degree in Electrical Engineering at COPPE/UFRJ in 2012 and received a “Magna cum Laude” Engineer Degree in Computer and Information Engineering from UFRJ in 2011. In 2017, he was a postdoctoral fellow in the Electrical Engineering Program at the Universidade Federal do Rio de Janeiro. His research interests include network security, next-generation networks, and Future Internet applications.
