E2E Network Slice Assurance for B5G/6G: Realizing Data Collection and Management, MLOps, and Closed-Loop Control

Assurance for network slices is a cornerstone for emerging application verticals such as vehicle-to-everything (V2X) and Industry 5.0. To achieve per-slice Service Level Agreement (SLA) assurance, an efficient network slice assurance framework is required. In this paper, we propose an end-to-end (E2E) slice assurance framework that addresses the requirements of assurance use cases. We design and implement the major components for a slice assurance framework for the E2E network: data collection, MLOps, and closed-control loops. We leverage open-source software to build the framework, and we provide experimental evaluations on real network devices and datasets.
