Zusammenfassung
Service requirements and the increased complexity of Fifth Generation (5G) applications and use cases, along with the transition towards virtualization and cloudification, are generating a strong interest in network traffic analysis. Network management and orchestration can be used to proactively tackle complex and data-driven environments to improve the performance across the entire network and meet the stringent Quality of Service (QoS) requirements for the different use cases.Time-series forecasting is one of the most important proactive approaches in communication systems. Thus, in this work, the performance of different prediction models - statistical models, Machine Learning (ML) and Deep Learning (DL) models - is evaluated using a virtualized 5G mobile network implemented in a cloud environment. The data used to train and validate the models is gathered while an operational User Equipment (UE) is connected to the core network and performing various activities. Performance evaluation of the implemented models is conducted using mathematical metrics and a graphical comparison. The results indicate that DL models outperform the statistical and ML models.
