6G-BRICKS

Motivated by the necessity of validating the 6G-BRICKS testbed, DIGIT presents a multi-tenant Digital Twin-based testing framework that supports multiple vertical applications in its service layer. Here, tenant data coexists on the same framework deployment, which requires software-based isolation. In the physical layer, this support and isolation are achieved by deploying User Equipment (UE) agent programs which support use-case-specific plug-ins for vertical applications in different domains. Additionally, these services should be maintained with a stable performance against the increasing number of users. Here, Digital Twins arise as a key technology that enables us to handle the 6G requirements in dynamic verticals by providing what-if analysis capability and valuable insights for real-time decision-making. In addition, cloud-native microservice-based architectures enable highly modular, scalable, and resilient software architectures. Therefore, the integration of these two technologies will provide a flexible management framework by effectively addressing the 6G implementation challenges. With its microservice-based architecture, DIGIT will provide digital twinning services according to desired performance parameters, such as high throughput and low latency, with a controllable twinning frequency to optimise the operation of services.  For onboarding and monitoring verticals, DIGIT will integrate with one of the 6GBRICKS enablers, DMO, via a TMF compliant API. To validate the 6G-BRICKS testbed and the DIGIT framework, an emergency scenario optimisation in a transportation network use-case will be implemented.
