ISG NFV

Development of an open and interoperable ecosystem enabling lifecycle management of virtualised network functions, hosted on independently deployed and operated NFV infrastructure platforms.

ETSI’s Industry Specification Group on Network Functions Virtualisation (ISG NFV) is at the forefront of transforming global networks into agile, cloud‑native, software‑driven platforms. We define the standards that unleash innovation, enabling operators and vendors to deliver high‑performance services with unprecedented flexibility and automation.

As the telecoms landscape moves toward open, intelligent and highly scalable architectures, ISG NFV works with the global community to drive the virtualisation technologies powering tomorrow’s connected world.

Key areas of work

Cloud icon

Cloud‑native and containerised network functions

As the industry shifts toward microservices and container‑based deployments, ISG NFV develops the specifications required to support cloud‑native Virtualised Network Functions (VNFs) and container infrastructure management. Our work enhances NFV to support multi‑network container connectivity, dynamic capacity, deployable modules and modern Continuous Integration/Continuous Delivery (CI/CD)‑driven operational models. This ensures NFV remains aligned with cutting‑edge cloud technologies.

Performance, reliability, security & energy‑efficiency

ISG NFV provides the technical foundations that ensure virtualised and cloud‑native networks remain secure, reliable and carrier‑grade. Our work covers performance metrics, hardware‑independent acceleration, resilience models, security requirements, attestation, trust frameworks and guidance for energy‑efficient deployments (“Green NFV”). These capabilities allow operators to meet stringent operational demands while innovating on new architectures.

Interoperability, standards evolution & industry enablement

ISG NFV is cultivating an open, interoperable ecosystem that supports vendors, operators and open‑source communities. We develop specifications, guidelines and release frameworks that ensure consistent interfaces, reusable models and cross‑vendor compatibility. Through continuous collaboration and evolution we help accelerate NFV adoption, integrate new technologies and transition smoothly toward the Telco Cloud of the future.

  • What we do

    ISG NFV develops standards that enable the telecommunications industry to build on agile, software‑driven and cloud‑native architectures. We design the models, interfaces and frameworks that ensure network applications—whether virtualised, containerised, serverless or AI‑driven—can run efficiently, securely and reliably across distributed Telco Cloud environments. Our work defines how modern networks are architected, deployed, automated and assured, supporting operators on their path to 5G Advanced, 6G and beyond.

    We continuously evolve the Telco Cloud Architecture introduced in NFV Release 6, providing a forward‑looking framework that unifies applications, infrastructure, platform services and orchestration. We also maintain and enhance the extensive body of specifications developed since the early phases of NFV, ensuring strong interoperability, backward compatibility and a smooth migration path for existing deployments.

    ISG NFV drives industry alignment by producing detailed specifications, informative studies, performance and security requirements, and interoperability guidelines. Through our releases, testing initiatives and collaboration with operators, vendors and open‑source communities, we foster a vibrant multi‑vendor ecosystem. Our work empowers industry to innovate rapidly, simplify operations, enhance automation and deliver next‑generation services with confidence.
