Deliverable D3.1 Baseline architecture and deployment objectives

The scope of this deliverable is to report on the initial activities for the network planning in 5G-TOURS. The project spans three trial sites (Turin, Rennes, and Athens), which are part of the 5G EVE infrastructure. The main contributions of this document can be summarized in the following three areas: • The initial discussion on the overall 5G-TOURS architecture, which relies on the 5G EVE platform, and the possible needed extensions to support the innovative use cases defined by WP2 “Use Cases design”. In particular, we discuss the extensions of the Management and Orchestration (MANO) framework, which needs to support the following three functional innovations developed in the project: o The introduction of Artificial Intelligence (AI) into a Data Driven management of the network. In particular, the relationship between the 5G-TOURS architecture and the ones defined by the major standard development organizations, such as ETSI or 3GPP, are discussed. o The inclusion of specific Broadcast modules in the architecture. This is of paramount importance for the immersive media use cases which will be developed in the Turin trial site. In particular, we focus the discussion on the relevant standard elements defined by 3GPP. o The integration of an enhanced Service Layer in the management system, to provide the verticals with efficient ways to manage their network slice. This innovation, which is going to be developed throughout the platform, also has to rely on the available software components created for the host platform, 5G EVE. • The detailed development plan for the infrastructure in the three trial sites. We especially discuss the capabilities of the sites along the following three main dimensions: o The extensions planned by each partner involved in the trial sites about the planned extension with respect to the 5G EVE platform. Some of the use cases need additional infrastructure (both hardware and software) to support the needed network requirements. Thus, we also discuss the available capabilities with respect to the ones needed by the different use cases. o The phasing of new functionality along the 5G-TOURS phases and the 5G EVE platform releases. This also includes fundamental aspects, such as spectrum allocation. o The integration of the novel functionality in the available network architecture. • The initial description of the development plans for the three innovations that will characterize the 5GTOURS network deployment. In particular, we detail the baseline software components that will be leveraged for their implementation, and an initial evaluation of different software architecture options. These points will be further detailed in the subsequent releases of the work package deliverables. The work performed by this Work Package “Network architecture and deployment” for the editing of this deliverable has been strictly coordinated with the one of Work Packages 4, 5 and 6, which focus on the vertical development of each test site respectively.
