Optimizing Key Value Indicators in Intent-Based Networks through Digital Twins aided service orchestration mechanisms

As Beyond 5G networks advance, efficient service orchestration is crucial to meet diverse performance demands, including security, economic, and environmental needs. Leveraging insights from Network Digital Twins (NDTs), multiple service orchestration options can be explored to optimize resource utilization and delivery processes. However, adhering to Service Level Agreements (SLAs) remains challenging due to network heterogeneity and their evolving capabilities. To tackle this challenge and fulfill novel value requirements expressed through Key Value Indicators (KVIs), we explore Intent-Based Networks (IBNs) to align operations with consumer intents. Our proposed model jointly considers performance and value requirements and minimizes SLA violations by combining NDTs and IBNs to orchestrate Beyond 5G services. Several resource configuration options, which foster collaborations among domains to handle service requests, are thus explored to adhere to established SLAs. Modeled as a many-to-many matching game between domains and service requests mapped into intents, our model significantly reduces SLA violations related to latency, throughput, costs, and security requirements, by up to 22.44% compared to baseline techniques.
