description: In the evolution of the telecommunication system towards a fully deployed 5G network, we<br> have reached the phase of verifying the new technologies and validating the 5G network Key<br> Performance Indicators (KPIs) in an end-to-end (E2E) approach. The 5GENESIS project, under<br> the EC ICT work programme, brings together several 5G platforms with the end goal to unveil<br> the potential of a truly full-stack and E2E 5G Facility that meets the targeted KPIs.<br> Towards this end, 5GENESIS has proposed a functional architectural blueprint relevant to the<br> implementation of an experimental Facility, capable to execute trials and KPI validation<br> activities. On the basis of the work performed as part of the analysis and requirements study<br> presented in Deliverable D2.1, this current deliverable sets out to expand the architectural<br> blueprint to a reference architecture specification that will:<br> • facilitate a common view across the five Platforms, while preserving the Platforms’<br> specific technological features and administrative independence,<br> • enable interoperability between the Platforms and re-usability of common components<br> • support further experimentation projects, in particular those focused on vertical markets,<br> offering one common interface towards the experimenters,<br> • engage a wide diversity of technologies and chain innovations that span over all domains,<br> achieving full- stack coverage of the 5G landscape,<br> • unify heterogeneous physical and virtual network elements under a common<br> coordination and openness framework exposed to experimenters or vertical industries,<br> • enable E2E slicing and experimentation automation,<br> • align with existing 5G standards and pre-existing H2020 work.<br> The present document starts with a short review of the main requirements as provided in<br> deliverable D2.1. It then presents a distilled summary of the technologies and standards that<br> the project builds upon, discusses how the 5GENESIS approach is related to these, and<br> documents the envisaged contribution towards the implementation of a 5G experimentation<br> platform. Based on this background and the well-defined architectural design principles<br> introduced, the study delves into the 5G Facility reference architecture to specify in more detail<br> each of the three layers (introduced in D2.1) and their components, as well as interactions<br> among them, concluding to a concrete reference architecture specification. Finally, each<br> Platform presents in a compact manner which reference architecture components will be<br> enhanced in the context of the 5GENESIS project and what are the candidate technologies that<br> might be used as starting points.<br> The key technical achievements of this deliverable can be summarized as follows:<br> • Introduction of the reference architecture for the Experimentation Facility, which will be<br> used by all the individual Platforms,<br> • Description of the components and sequence diagrams for the different architectural<br> layers, as well as for the east/west interface to peer Platforms,<br> • Documentation of the 5G technologies that will be integrated into the Platforms for<br> further alignment with 5G standards,<br> • Presentation of the proposed enhancements and starting points in terms of technologies<br> used for the architectural components per Platform.
