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


Panel
borderColor#549BC1
bgColor#549BC1

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

Column
width85%

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

Column

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.

The search for a blueprint led to the selection of the TM Forum’s OpenDigital Architecture (ODA), adopted by and driving the digital transformation of most communication providers. ODA is a reference framework which provides a common understanding and generality in an environment where each NREN is free to choose its own path towards OAV - including architecture, design and implementation. Read more...

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.

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


Panel
borderColor#549BC1

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

 

The Focus Group OAV Architectures is working on identifying a service architecture that allows the creation of new services and workflows that can be shared within the community in a multi-domain fashion with a corresponding orchestration process.

This should result with potential candidate architecture(s) to be used as a blueprint for a common framework upon which the community can develop solutions (or automated agents) that can be orchestrated in a potentially multi-domain environment.

In order to select suitable architecture candidates that could fit the community needs, the OAV FG investigates available architectures that aim to solve all or some of the aspects of OAV. The group then identifies commonalities in terms of module functionalities, APIs and data models and performs a deep dive analysis. This work is followed by a cross comparison with existing proprietary solutions in the community and may enable harmonisation in the multi-domain environment. The work of the FG also involves continuous monitoring of architectures and new solutions as they become available.

Ultimate goal: to provide benefits to the community for the development and implementation on future single and multi-domain digital services.
