Open Source Community Connects Global 5G Cloud Native Network


  • Collaborative effort between LF Networking and global networking ecosystem shows open source approach to building cloud native 5G on top of Kubernetes
  • First Proof-of-Concept of live, end-to-end, open source 5G network displayed on keynote stage at KubeCon + CloudNativeCon North America 


SAN DIEGO, Calif.  KubeCon + CloudNativeCon North America – November 20, 2019 – LF Networking (LFN), which facilitates collaboration and operational excellence across open networking projects, today demonstrated an end-to-end, global, 5G, cloud native network live on-stage at KubeCon + CloudNativeCon North America. As a thought leader in generating technology from multiple sources based on telecom 5G requirements, LFN’s OPNFV community shepherded the cutting-edge Proof-of-Concept (PoC), which illustrates how to build, connect, and manage a global 5G network – including on-prem, cloud, and edge operations – on open architecture running network services using Kubernetes.

As global communications providers gear up to deliver high-speed connectivity to support new services and use cases (e.g. autonomous vehicles, smart cities, specialized applications, IoT, AR/VR, and more), the need for low-latency, high-bandwidth, scalable networks is more important than ever. Conventional communications and connectivity hardware will not sustain next-generation mobile technology, so the need for cloud native architectures is essential for delivering the performance, capabilities, and automation that 5G requires.

The LF Networking community, comprised of major projects such as ONAP, OPNFV, OpenDaylight,,  Tungsten Fabric and more — account for more than 70 percent of the world’s mobile subscribers through participating carriers. It serves as the de facto open source umbrella for helping telcos evolve.

Cloudifying the Network

It’s no secret that Kubernetes has gained significant traction in the cloud and enterprise software ecosystem, but less widely known is how this momentum is now moving into global telco networks as the next major area of adoption. Benefits of cloud native adoption for telcos include operational consistency, application resilience, simplified and responsive scaling at the microservice level, simplified integration with enterprise-facing cloud native applications, and improved portability between public, private, and hybrid cloud environments. A team made up of volunteers from several project communities, companies, and network operators have taken a cloud native approach to developing an end-to-end 5G network Proof-of-Concept (POC) built on open source infrastructure.

The POC uses a prototype network to connect a live call over Points-of-Presence (PoPs)  in San Diego, Montreal, Sophia Antipolis, and a hybrid public/private cloud to deliver a fully containerized 5G network live on stage. The demonstration illustrates both how the telecom industry is using cloud native software to build out their next gen networks, and also shows solution providers and developers what’s possible in this exciting new space.

I am incredibly impressed by the collaborative effort to build a 5G network from the ground up in the open source community with a cloud native approach. It’s fully end-to-end, adheres to 5G specifications, and bridges the gap between the telecom industry and cloud native computing,” said Heather Kirksey, vice president, Community and Ecosystem Development, the Linux Foundation.

Power of Open source

The initiative was born in LF Networking’s Open Platform for Network Functions Virtualization (OPNFV) project, which brings the telco ecosystem together to test, iterate, and collaborate on a common NFV Infrastructure (NFVI). By working closely with standards organizations and integrating components from upstream projects, OPNFV conducts performance and use case-based testing on a variety of solutions. The community works upstream with other open source groups – including CNCF, ONAP, OAI, and more – to bring contributions and insights in the form of blueprints, patches, and new code. The project also supports the OPNFV Verification Program (OVP) that verifies labs, infrastructure, and virtual network functions (VNFs).

It’s through this collaborative work that the end-to-end 5G Cloud Native Network POC came about. With over 100 individuals working on this initiative alone, it truly represents the power of open source: diverse groups coming together to begin integrating cloud native approaches to daunting industry challenges and optimizing 5G.

Also aligned with the efforts of the Common NFVI Telco Taskforce (CNTT) – a joint effort hosted by the GSMA and the Linux Foundation operating as an open committee responsible for creating and documenting an industry-aligned Common NFVI Framework – the initiative allows for early proofs-of-concept and learnings that will feed into and inform the cloud native work of the CNTT, which is expanding  its portfolio of Reference Architectures. Focus areas include Containerization, Kubernetes-based Cloud Native stacks, and Container-based network functions’ validation-based requirements.
