A variety of use cases are investigated to provide an illustration of how different types of architectures can be mapped to this flexible OAV reference blueprint or TM Forum's Open Digital Architecture (ODA). The use cases include a number of NREN architectures from very diverse environments with varying internal processes and workflows and show how they would identify structures and elements to group them within the ODA functional blocks.

Other use case examples include commercial (5G) and research-based architectures (TALENT) and show how they can make use of this reference architecture.

Interested in what ODA could do for you?

Let us provide you with a mapping of your own organisation’s architecture to ODA!

Or simply contact us at oav@lists.geant.org and we will work with you and provide you more details on how this approach based on functional blocks could streamline your workflows and make your systems more agile and efficient for easy automation.



NREN Architectures

Analysing NREN architectures from an orchestration, automation and virtualisation (OAV) point of view using a common reference architecture helps align efforts, and find similarities in the way different functionalities and components are implemented, which in turn facilitates potential collaboration between organisations and future interoperability. In pursuit of this goal, the GN4-3 Network Technologies and Services Development Work Package (WP6), Network Services Evolution & Development task (T2) selected the TM Forum Open Digital Architecture (ODA) as a reference blueprint architecture that can be used for such cross-comparison. The rationale for that choice is described in Deliverable D6.6: Transforming Services with Orchestration and Automation and in the White Paper: OAV Architectures.

Column
width30%

The PMP service is a platform consisting of central components and a set of small nodes that perform regular active performance measurements towards several Measurement Points (MPs) located in the core of the GÉANT network, and operated by the GÉANT network operations centre. The PMP operational team maintains an instance of the Maddash dashboard [PMD] for visualising performance testing between the PMP service instances in NRENs and GÉANT PoPs.

PMP incorporates different tools for different functionalities and components. Using a common reference architecture to analyse this network monitoring platform from the point of view of  orchestration, automation, and virtualisation helps enables a better understanding of the system, identifying commonalities in the way these various functionalities and components are implemented, as well as a cross-comparison with other platforms, which in turn promotes future interoperability and integration.

The Service Provider Architecture (SPA) [SPAW] is a service management platform that is based on the TM Forum Open Digital Framework. Its development is continued from the previous generation of the GÉANT project (GN4-2) and its Self-Service Portal graphical user interface (SSP GUI) is used for the service order management process of the GÉANT Connection Service (GCS) [SSPM20]. The SPA solution can be used as the basis for the development of a digital platform and to manage the lifecycle of any type of service, including networking, trust and identity or security services.


Column
width30%

While all components of the SPA follow the principles of the building blocks architecture, the solution also incorporates other aspects of OAV design principles, such as:

  • Ability to compose services and resources.
  • Abstract, technology-agnostic modelling of all resources and services.
  • Distinction between products, customer-facing and resource-facing services.
  • Support for both physical and virtual networks.
  • Ability for east-west integration with systems from other domain.

The European Open Science Cloud (EOSC) initiative [EOS20] is part of the EuropeanCommission’s effortto increase the competitive digital economy in Europe. The main idea of the initiative is to support Open Science, which in turn will enable a more agile approach to innovation.  The main goal of EOSC is to provide researchers from different research fields with the means necessary not only to conduct research, but alsotomake their research outcomes open to the wide community. Thus, in essence, the end goal is to create a cloud-based virtual environment that will provide a number of open services that can be used to store, manage and analyse research data.Six different actions are being implemented in parallel to achieve this goal, described in the EOSC implementation roadmap [ETS20]. One of the action lines focuses on the architecture of the virtual environment,whichshould achieve a federated, seamless view of all available research infrastructures and services built on top.

One of the main requirements for future architectures and digital service providers is to be able to transform all manual management of network and services into Automated and Autonomic Management & Control (AMC) so that the system dynamically responds to the changing environment. This behaviour is also known as autonomics and is the main focus of the Generic Autonomic Network Architecture (GANA) [GANA16]. In other words, the GANA reference model provides a way to build autonomic architecture using a generic AMC framework that can integrate with any type of network management architecture.

The ETSI Network Technologies (NTECH) Autonomic network engineering for the self-managing Future Internet (AFI)workinggroup leads the AMC standardisation efforts that will transform the traditional networking environment into a smart and intelligent network with a number of self-* features including self-healing, self-configuration, self-optimisation and others.

The Generalized Virtualization Model (GVM) describes an architecture that supports managing the lifecycle of different network topologies as virtual network slices over a physical infrastructure in a fully automated fashion. These virtual networks are environments where abstracted virtualised objects,called resources, can be defined, instantiated and arranged to create application-specific insulated networks and services. This process is performed via agraphicaluserinterface (GUI) and without the need for human intervention from network operationsor engineering teams.

SDN for End-to-end Networked Science at the Exascale (SENSE) [SEN20], [MON18]was developed in a research project with the goal to provide a network architecture that will facilitate the rapid deployment of smart network services in support of science applications. The main contributors to this project are ESnet/Lawrence Berkeley National Laboratory, California Institute of Technology, Fermi National Accelerator Laboratory, Argonne National Laboratory and the University of Maryland College Park.
The architecture was developed with next-generation big data/exascale science workflowsin mind that will require intelligent network services in cloud computing, AI and machine learning. The idea is to support scientists and their science workflows with a system that will automatically build virtual guaranteed networks over large-scale distributed storage and computing infrastructures without any human intervention and without the static non-interactive network infrastructures in place today.

This document analyses the mapping of the SURFnet architecture to the TM Forum’s Open Digital Architecture, as part of the GN4-3 project’s ongoing activity in the Network Technologies and Service Development’s work package to provide a standardised view of the components and implementations of orchestration, automation and virtualisation within the NRENs. Overall, it can be concluded that the SURFnet OAV architecture, although independently developed, is very much aligned to the ODA’s core principles and design concepts.

Using a common reference architecture to analyse NREN architectures from an orchestration, automation and virtualisation (OAV) point of view helps align the NRENs’ efforts and find commonalities in the way they implement different functionalities and components. To this end, the GN4-3 WP6 Network Technologies and Services Development OAV team has selected the TM Forum Open Digital Architecture (ODA) to be used as a reference blueprint architecture for cross-comparison. This document presents an analysis performed by the WP6 OAV team of the different functional aspects of the SURFnet network architecture, mapping its components to the TM Forum ODA. The mapping highlights the main characteristics and functionalities of the current SURFnet network architecture and how they fit into the main functional domains of ODA.

5G is a mobile technology that is addressing, by design, a broad range of requirements: very high data rates, very low latency, low energy consumption, high scalability, improved connectivity and reliability, and improved security [FGPPP18], [FGPPP20]. The 5G specifications focus on serving mobile operator needs in terms of extreme mobile broadband services and include several features to support vertical industries in terms of enablers for an industrial Internet of Things (IoT)and Ultra Reliable Low Latency Communications(URLLC)[FGPPP20]. Within the 5G system, end-to-end (E2E) network slicing, service-based architecture, Software-Defined Networking (SDN) and Network Functions Virtualisation (NFV) are seen as the fundamental pillars of the 5G architecture.  Read more...

TALENT

Column
width30%
Terrestrial Satellite Resource Coordinator (TALENT) is a coordination tool which provides end-to-end services over satellite domain, radio system, cloud and Mobile Edge Computing (MEC) resources [TAL19]. It provides a single and easy-to-use point of interaction for all stakeholders involved in the ecosystem, such as terrestrial and satellite operators as well as different 5G verticals. TALENT is completely inline with 3GPP and ETSI definitions, extending them towards satellite systems.The original idea of TALENT is based on the definition of hierarchical and distributed orchestration [HDO17], where an overarching orchestrator is able to manage and coordinate several independent domains (satellite, radio and cloud). It is assumed that a domain manager (DM) exists in each domain that can work with the resources of this domain. In this sense TALENT becomes a light, scalable and efficient solution, agnostic to elementsof domains coming from various vendors.Read more...
