Digital Platform Concepts and Principles*
*based on the TM Forum Open Digital Architecture
Architecture Building Blocks
√ Decouple functionalities into separate components
√ Use the single source of truth approach to data storage
√ Implement DevOps to develop/maintain each component
√ Define common service abstractions
Open APIs
√ Promote a multi-vendor environment where each component has a well-defined API
√ Ensure interoperability with open API specifications
√ Use same APIs for intra- and inter-domain integration
Orchestration and Automation
√ Start incrementally: automate repetitive daily tasks first
√ Orchestrate multiple components using processes
√ Innovate: Don't improve existing manual processes or compromise - invent new, more efficient workflows
Introduction to Digital Platforms
As digital transformations bring new challenges to networking ranging from big data transfer and storage to vast scale Internet-of-Things (IoT) applications, network providers must find ways to automate processes to be able to manage increasing operational workloads. To facilitate such automation, providers need to move to abstracting network resources to ensure agility and technology agnostic network service behaviour. These challenges do not only apply to commercial providers, but also to the NREN communities. For GÉANT, with its more than 40 country members, it is therefore crucial to drive this network evolution forward with a common strategy, in a way that would allow for automation, orchestration and virtualisation (OAV) of network services in a multi-domain and inclusive fashion, bringing all partners on board while accommodating already existing solutions.

List of features / capabilities to be supported by an OAV architecture
The Network eAcademy team has investigated a list of required features and capabilities necessary to be supported by an OAV architecture solution of an research and education (R&E) network ecosystem. This list is by no means exhaustive or prioritised in any way, and can be used as a supporting cross-reference checklist when deciding about new architectural designs or approaches, technologies or components.

Investigated Architectures
A number of architecture proposals and solutions are discussed in this section in order to provide a general overview of the existing implementation paths and their major focus. The short list of investigated architectural solutions has been compiled by the Network eAcademy in order to cover diverse approaches including the most prominent examples given by standardisation bodies, but also proposals that have played a major role in our community being part of research projects.

Mapping Use Cases and NREN Architectures to ODA
The Orchestration, Automation and Virtualisation Journey
From a traditional OSS/BSS
√ Analyse components and functionalities
√ De-couple & de-duplicate
√ Expose components via APIs
√ Automate manual tasks per component
√ Use orchestrators to implement complex processes spanning multiple components
Via a digital platform
√ Agree on terminology to understand each other
√ Define common service abstractions
√ Ensure interoperable interfacing via common Open APIs
√ Federate with other NRENs or commercial providers
To an interoperable community
√ Employ on-demand provisioning of multi-domain services using common APIs and data models
