Title: Recent Research and Development of free5GC
Title: Recent Research and Development of free5GC
Summary: The free5GC is an open-source project dedicated to the development of 5th-generation (5G) mobile core networks. The primary goal of the project is to implement the 5G Core (5GC) as defined in 3GPP Release 15 (R15) and beyond. Due to its comprehensive features, openness, and excellent interoperability with many commercial base stations and cellular phones that comply with international standards, free5GC has been increasingly adopted by researchers as a platform for system verification and has also been used as a foundation by companies worldwide. Currently, free5GC is advancing toward R18 and beyond. In this talk, I will first introduce free5GC and then present our recent research and development efforts with the platform, including data plane acceleration using P4 Tofino switches, 5G-TSN integration, Access Traffic Steering, Switching, and Splitting (ATSSS) to support both TCP and UDP traffic, active-active failover and load balancing for control plane traffic, ML-based 5G core network load prediction, and 5GLAN.

Title: Probabilistic Digital Twin for Future Network System Operation and Management
Title: Probabilistic Digital Twin for Future Network System Operation and Management
Summary: In the Beyond 5G/6G era, digital twins are expected as a key enabling technology for advanced Cyber-Physical Systems (CPS) to solve real-world challenges such as human–robot collaboration, smart cities, and autonomous mobility. Digital twins are used not only to digitize and operate real-world CPS applications (Digital Twin by B5G), but also to enhance the operation and management of future network systems (Digital Twin for B5G). Furthermore, digital twins are envisioned to serve as a unifying framework that bridges CPS and network systems, thereby enabling their integrated and synergistic optimization. This talk will introduce a probabilistic representation of the digital twin for both CPS and network systems, with a particular focus on achieving a high level of reliability and efficiency in handling uncertainties associated with the perception and control of real-world environments and systems. Then, as examples of specific research topics, this talk will introduce several studies conducted in our laboratory that focus on constructing probabilistic digital twins of real-world environments and network systems, and utilizing them for the control of CPS, network systems, or their integrated coordination.

Title: LLM-Driven Innovations in Network Management: Automating Configurations and Deployment
Title: LLM-Driven Innovations in Network Management: Automating Configurations and Deployment
Summary: The most transformative information technology in recent years is undoubtedly Generative Artificial Intelligence, particularly Large Language Models (LLMs). In this keynote, we will examine how LLMs are reshaping the field of network management. The long-standing vision of intent-based networking (IBN), once considered a distant goal, is now becoming attainable with the advent of LLMs. Yet, research on LLM-driven network management remains in its infancy, with many challenges still ahead. We will highlight current research efforts in automating software-defined network configuration and deployment through LLMs, and discuss both the opportunities and limitations of these approaches. Ultimately, this talk will explore not only the broad potential of LLMs across network management and related domains, but also the hurdles that must be overcome to achieve fully automated, LLM-empowered configuration management.
