SONATA: a Brief Overview

We're kicking off the SONATA blog with a brief overview of the project. In the future you can look forward to insights into the latest happenings of software networks in the telecom industry.

And now... an overview of SONATA:

Software Defined Networking (SDN) and Network Function Virtualization (NFV) are emerging as major transformational technologies, evolving the telecom sector with new network capabilities and business opportunities. SONATA addresses the significant challenges associated with both the development and deployment of the complex services envisioned for 5G networks and empowered by these technologies. The project targets the flexible programmability of software networks, supporting network function chaining and orchestration. Innovations will make service platforms modular and easier to customize to the needs of different service providers, and introduce a specialized DevOps model for supporting developers.

Specific objectives include:
- Reduce time-to-market of networked services, by a) streamlining development with abstract programming models and SDK; and b) applying a DevOps model that integrates operators, manufacturers and third-party developers.
- Optimize resource utilization via orchestration and reduce costs of service deployment & operation, by a) mapping complex services to connectivity, computing and storage resources; and b) automatically re-configuring running/competing services.
- Accelerate the industry adoption of software networks, by a) supporting the full service lifecycle: development, testing, orchestration, deployment, management and operations; and b) defining a roadmap for uptake of its results towards the larger transition to SDN/NFV.

SONATA’s open source results to fulfil these objectives will include:
- programming model and SDK to facilitate service development
- service platform with modular orchestration framework
- DevOps model for software networks that integrates operators with external stakeholders

Use Cases

SONATA includes industry use cases and a pilot program for demonstration of its service platform, orchestrator, programming model, SDK and DevOps approach. Key examples focus on Virtual Content Delivery Networks (vCDN) and Mobile Edge Computing (MEC).

Technical and Research Challenges

SONATA tackles challenges in the development and deployment of NFV-based services for 5G networks:
- models, methods and tools for programming virtualized services
- methods, enablers and algorithms for uniform and integrated orchestration of network services, on top of an infrastructure providing connectivity, computation, and storage resources
- tools for efficient and reliable deployment and management of developed services in a dynamic and scalable manner
- efficient integration of development and operations (DevOps) of services between multiple stakeholders

Impact on the Telecom Industry and Stakeholders

SONATA’s open source results will have a diverse impact on an expanding telecom sector, including operators, manufacturers and third-party developers:
- reduce time-to-market for networked services
- optimize network management, reducing OpEx
- increase reliability and QoS for 5G networks and deployed services
- decrease barrier of entry and empower third-party developers
To widen the reach of the project’s impact, SONATA will collaborate with key community initiatives, including OPNFV, OpenDaylight, OpenStack, ITU-T and ETSI’s NFV ISG.
