Digital Twin-Based Intelligent Network Management

Communication networks today are becoming more and more complex as a result of the introduction of 5G/6G technologies, the Internet of Things (IoT), cloud computing, edge computing, network virtualization, and software-defined networking (SDN). Existing methods of managing networks mostly depend on fixed configurations, manual monitoring, and dealing with faults after they occur, which makes them inadequate for coping with varying traffic conditions, changing resource needs, and unforeseen network failures. In order to meet these challenges, this paper puts forward an intelligent network management framework that combines Network Digital Twin (NDT) technology with Artificial Intelligence (AI) and Machine Learning (ML). This framework produces a real-time digital version of the actual communication network and keeps it updated by means of real-time network data. It is made up of six main layers: the physical network layer, the data collection and synchronization layer, the digital twin layer, the AI/ML analytics layer, the decision-making and simulation layer, and the control and feedback layer. The approach described enables real-time network monitoring, traffic prediction, detection of anomalies and faults, resource optimization, scenario-based simulation, and proactive network management. By analysing network behaviour, AI/ML models assist in making predictive decisions before any changes are implemented on the physical network, thus reducing operational errors, service interruptions, and network downtime. The performance of the proposed framework can be assessed using a number of key performance indicators such as latency, throughput, packet loss, resource utilization, fault detection time, prediction accuracy, energy efficiency, and synchronization delay. Combining NDT with AI/ML offers a promising way of achieving autonomous, adaptive, and proactive management of next-generation communication networks. Nevertheless, there are still a number of problems to be overcome, such as real-time synchronization, computational complexity, scalability, data security and privacy, communication latency, and the accuracy and reliability of the AI/ML models. Future research should concentrate on tackling these issues and on developing scalable, secure, and highly accurate AI-driven digital twin solutions for next-generation communication networks.
