NFV-SDN 2025 (IEEE Conference on Network Function Virtualization & Software Defined Networks) is an academic conference held in Athens, Greece on 2025-11-10. The paper submission deadline is 2025-06-15. Acceptance notifications are sent on 2025-08-30.
Network virtualization has transformed how our infrastructures are connected, built, and operated. Network services often rely on the disaggregation and reconstitution of Network Functions through Network Function Virtualization or NFV. When combined with dynamic and automated network configuration concepts, or Software Defined Networks (SDN), advantages of overall improved performance, reduced vendor lock-in, more rapid adoption of new features, and increased operational efficiency are realized.
Over the past decade, network operators around the globe have demonstrated the advantages of virtualization in portions of the network; yet much work remains to bring these benefits across the communication infrastructure. Research and development of virtualization technologies, from the Radio Access Network to the network core, has the potential to increase resiliency, security, and power efficiency and provide more effective operationalization through automation and Artificial Intelligence.
The recent Cloudification and Cloud/Container Native Functions (CNF) practices continue to challenge network operators and their ecosystem partners from early research and into practice, while new and innovative applications at the edge demand even more attention from industry and academia. NFV, CNF, and SDN are accepted evolutions in all areas of network concepts and technologies today. They are accelerating the introduction of technologies and applications, requiring further advances in several areas of network programmability and network automation.
Significant enablers for rapid adoption include shifts towards open-source software and hardware development, the convergence of IT and telco tools and technologies, and the alignment of operational processes. Integration of the latest research in software technologies, algorithms, hardware design, etc., driven by competition to adopt the best ideas, is helping to drive global acceptance of network virtualization.
The 2025 IEEE NFV-SDN conference is an important forum for the ongoing exchange of the latest ideas, developments, and results amongst ecosystem partners in both academia and industry focusing on 6G deployment initiatives in worldwide. The conference fosters knowledge sharing and discussion on new approaches and works addressing gaps and improvements in virtualized enabled architectures, algorithms, and operational frameworks for virtualized network functions and infrastructures.
