Investigating 5G Network Slicing Resilience through Survivability Modeling

The deployment of 5G networks has brought significant advancements in mobile communication, enabling novel applications and services with diverse requirements. Network slicing, a crucial technology for realizing 5G’s full potential, allows operators to create multiple, logically separate networks on a shared physical infrastructure. However, ensuring the resilience and survivability of network slices during network failures is a crucial challenge that needs to be addressed, particularly for critical infrastructure services. This paper presents an ongoing research project investigating the survivability of network-sliced 5G systems during network failures, focusing on the ClusPR framework for service chaining and resource allocation.The study aims to: 1) develop a framework for assessing the survivability of network-sliced 5G systems during and after failures; 2) explore factors influencing the resilience of various slicing approaches in challenging events; and 3) apply findings to design resilient 5G networks and develop strategies for handling undesired events. As the project advances, the expected results will provide valuable insights and heuristics into proactive and reactive strategies for maintaining the continuous operation of critical services in 5G networks during network outages.
