The activity of the project is based on Work Packages. The Work Packages 1 and 2 play a driving role, defining the architecture and the use cases and managing the set-up, the roadmap and the management of the site facilities. The use cases have been conducted both with players that were already in the consortium, as explained in the report for the first year, and with external players from ICT-19/22 projects which adopted the 5G EVE platform to run their foreseen tests (see Figure 1 for an example).
The use cases are implemented in the Site Facilities managed in WP2. In this Work Package all the site facilities have been implemented and the corresponding use cases, both for internal and external players, managed. An Inter-Working Layer facility has been as well set-up in Italy allowing to perform multi-site experiments. In Figure 2 a description of overall layout of the network.
5G EVE goal is also to create a platform with interworking among the four site facilities. WP3 aims at ensuring the interworking and the orchestration, including multi-x slicing, among site facilities. In this final period, WP3 successfully implemented the inter-working layer, as a fundamental cornerstone of the whole project platform. In its final version, the IWL implements a distributed transaction logic in order to perform the deployment of a multi-site experiment (see Figure 3).
The tools definition to inter-operate the facilities and a portal to check and manage them is the focus of the WP4. The final version of the portal has been completed in the latest months and manages all services originally included in the 5G EVE project proposal, and some services requested during the project lifetime. Among the new functionalities delivered there is the full REST API to access all available services, as well as the extensions implemented on the graphical user interface to perform all experimentation phases (Figure 4).
“Model Based Testing Methodology” (WP5) aimed to have a template to be filled in by the verticals for requirements and to check if their work with the platform is feasible from a testing standpoint. In this context the final version of the 5G EVE testing and validation platform has been implemented (Figure 5), focusing on the execution of the experiment, the analysis of the collected metrics, the validation of the generated KPIs and the generation of the final reports provided to the experimenters for the use case data analysis.
The technical activities have been complemented by the business analysis, the standardization and the exploitation of the achievements (WP6), and by the international footprint (WP7).
