Scaling the future of Open RAN: Red Hat joins the OCUDU Ecosystem Foundation

At Red Hat, we’ve always believed that the most complex challenges in technology are best solved through open collaboration. This week, as announced by the Linux Foundation, Red Hat has officially joined the OCUDU (Open Centralized Unit / Distributed Unit) Ecosystem Foundation as a general member.

Launched under the stewardship of the Linux Foundation, OCUDU represents an important shift in how cellular networks are built. By creating a carrier-grade, open source software stack for 5G, 5G-Advanced, and 6G, the project aims to do for the Radio Access Network (RAN) what Linux did for the data center: Breaking down segregated technology areas and fostering an environment where RAN innovation moves at the pace of open source innovation.

Why does OCUDU matter to the Red Hat ecosystem and telecommunication service providers?

As the industry evolves toward 6G and future generations of technology, the demand for "AI-native" and software-defined architectures has never been higher. OCUDU provides the transparent, modular blueprint the industry needs to decouple specialized networking logic from underlying hardware.

For service providers and ecosystem partners, this means:

• Vendor diversity: Increased innovation in RAN stacks through open source.
• Business-critical security: Enabling continuous auditing and faster patching of RAN software.
• Interoperability: Streamlining the deployment of 5G/5G-A/6G capabilities on standard commercial off-the-shelf (COTS) hardware.

Engineering the foundation: OCUDU on OpenShift

Rather than building a vertical silo, our focus is on extending Red Hat’s continued leadership in the common telco cloud. By providing a single, integrated foundation for both legacy virtual machines (VMs) and modern cloud-native network functions (CNFs), we’re able to help service providers to stop managing ‘islands’ of infrastructure and start managing a cohesive network. Our work with OCUDU helps open RAN workloads become a native part of this common telco platform, delivering the operational sanity and consistency required now and in the future. 

To date, we have achieved several key milestones:

• Deployment on Red Hat OpenShift: We have successfully deployed the OCUDU gNB (Base Station) on Red Hat OpenShift 4.21.
• Streamlined testing: The core OCUDU software stack can be deployed without the need for complex third-party storage or networking bindings, simplifying the path to production for service providers.

The road ahead: What’s next?

As we look toward the rest of 2026, we are focused on working with our community partners to transform our initial efforts into fully carrier-grade deployment-ready solutions for the field:

1. Live hardware validation: We are progressing beyond the radio unit (RU) emulation phase to full scale hardware testing. By using Universal Software Radio Peripheral (USRP) equipment in our telco labs, we’re able to validate the performance of the OCUDU stack on the same physical infrastructure used in real-world deployments.
2. Community collaboration: We are working closely with SRS, the National Spectrum Consortium and the Linux Foundation to contribute to the foundation for carrier grade software with Red Hat OpenShift and Red Hat certified software from SRS that forms the base of the OCUDU project. This move helps the broader ecosystem contribute to and benefit from a standardized, open source RAN foundation."

The era of "6G in Code" is here. By combining the power of the OCUDU software stack with the reliability of Red Hat OpenShift, we are anchoring the next generation of global connectivity in an open, secure, and community-driven ecosystem.
