An Overview of Principles, Enablers, Metrics and Emerging Technologies for Resilient Networks

There are approximately 5.78 billion users [1] relying on mobile networks to access a wide range of digital services. Hence, the resilience of these communication networks is of the highest importance. In this paper, we define network resilience and outline key architectural design principles and their enabling technologies. We further describe relevant metrics for assessing network performance and examine emerging technologies, such as the integration of terrestrial and non-terrestrial networks, artificial intelligence–enabled network management and optimization, as well as innovative concepts like core network disaggregation and non-IP-based architectures. We identify current challenges and highlight critical research directions for the advancement of resilient mobile networks.
