On the selection of KPI-aware E2E paths for deterministic services in 6G networks

In the 6G ecosystem, the provisioning of deterministic services with KPI guarantees over multi-technological network domains requires the proper selection of the end-to-end (E2E) paths. Since each technological domain has its own capabilities and resources, in an E2E perspective, the proper selection of the domains to achieve the service KPIs is fundamental. The paper discusses the challenges of the E2E path/domain selection, provides an overall supporting control plane architecture and presents a proof of concept.
