5GZORRO_D3.3: Final design of the evolved 5G Service layer solutions

This deliverable describes the design of the evolved 5G Service layer solutions, in its final form as being realised in the 5GZORRO platform. The document builds upon the structure and the contents of D3.1 where the preliminary architecture and design choices were presented. It is intended to be a standalone version of 5GZORRO Service layer solutions design, aligned with the final version of 5GZORRO architecture reported in WP2. In addition to WP3 components design, the document includes descriptions of major technology enablers used to design and realise the 5GZORRO Service layer solutions, showing why these concepts (the DLT and the AIOPs) were chosen and how they have been applied in 5GZORRO context, both for realizing 5G Service layer solutions of WP3 (Identity and Permissions, Governance, Marketplace, Cross-domain Analytics & Intelligence) and in a broader context of Zero-touch Service Management and Orchestration developed in WP4. This final version of 5G Service layer solutions design is informed by the implementation activites performed across WP3 and WP4 (organized as several goal-oriented software development teams) as well as by the integration and validation activities ongoing as part of WP5 (Validation through Use Cases). To summarize, this deliverable complements the final version of 5GZORRO architecture, providing deeper level of detail for components and services contributed by WP3 along with their internal design and interworkings that will be further detailed in the last deliverable of WP3, D3.2, with low level descriptions of the software prototypes of evolved 5G Service layer solutions.EC approval: 10/02/202
