He contributed to the Monitoring and Alert infrastructure that is an integral part of the Aether Management Plane (AMP). He created multiple dashboards to simplify monitoring of various attributes of Aether, including resource health and subscriber activity.

Andy created “Aether-in-a-Box” (AiaB), a software tool that enabled developers and researchers to easily setup and deploy Aether’s SD-Core and Runtime Operational Components (ROC) for testing, validation and experimentation on a local machine. It offered a self-contained, simplified way to set up a private 4G/5G network with tools to manage and validate the network, enabling users to test network slices, application integration, and other core Aether features without requiring large-scale infrastructure. AiaB was also leveraged to build the Aether CI pipeline to run E2E integration tests and ensure the quality of Aether releases. AiaB inspired Aether OnRamp, which is the currently recommended method for deploying Aether.

Andy collaborated on the Pronto Project, a DARPA-funded project focused on building and testing new types of programmable and flexible 4G/5G networks to improve security and performance. The project was led by the ONF and included researchers at Stanford, Cornell, and Princeton universities. As part of this effort, he maintained a centrally-managed Aether at several of the universities for use in project research. He also supported researchers’ experiments to demonstrate and evaluate novel applications using Aether.

With other members of the Aether community (Larry Peterson, Scott Baker, Zack Williams), he co-authored a book based on hands-on experiences operating Aether and Pronto networks: Edge Cloud Operations: A Systems Approach. Andy was a key contributor to Intel’s open-source Edge Manageability Framework, a secure platform for delivering scalable edge solutions that aligns with the principles described in the Edge Cloud Operations book.

“Being a member of the Aether community has been a very rewarding experience.  My contributions have centered around “operationalizing” Aether so that it was easy to deploy, configure, and monitor.  As a result I have been fortunate to collaborate with many remarkable colleagues, including engineers managing their own Aether deployments, and researchers working to extend Aether with new capabilities.  I am proud of the project that we have built together and excited to see it being adopted by companies around the world.” – Andy Bavier

Andy received a B.A. in Philosophy from the College of William and Mary in 1990, a M.S. in Computer Science from the University of Arizona in 1995, and a Ph.D. in Computer Science from Princeton University in 2004.

He worked as a Research Scientist at the University of Arizona from 1996 – 1998, contributing to the Scout OS, a research OS for network appliances.  From 2004 – 2017, he was a Research Scholar at Princeton University, where he built and operated distributed testbeds (PlanetLab, VINI, VICCI, GENI) supporting research in distributed systems and networking. From 2015 – 2022 Andy served as a member of the technical staff at ON.Lab / ONF, where he worked on integrating edge clouds with telecommunication technologies in the CORD, SEBA, VOLTHA, and Aether projects.  He joined the Ananki ONF spin out that was formed to commercialize Aether.  After Intel acquired Ananki in 2022, he worked as a Cloud Software Development Engineer at Intel on the Edge Management Framework project.  Andy left Intel earlier this year and is taking time off to plan his next chapter.

As our research progressed, we evaluated a range of 5G core implementations for their real-world applicability, scalability, and cloud-native design. Among them, Aether/SD-Core emerged as the most production-ready platform—offering advanced features like Network Slicing, DPDK-SR-IOV and CNDP integration, and Dynamic Scaling capabilities.

Following extensive lab testing, we adopted Aether SD-Core as the foundation for several of our advanced R&D workflows. We integrated it with real radios, COTS UEs, and O-RAN components, validating its robustness in complex, large-scale deployment scenarios. These efforts were documented and shared through a series of technical demonstrations and walkthroughs, including:

We successfully integrated Aether SD-Core with open-source RAN solutions such as OAI and SRSRAN, and tested it with commercial O-RUs from LiteON, Benetel, and Accton, alongside various COTS UEs. Additionally, we performed extensive testing with simulators like UERANSIM and gNBsim, and used PacketRusher to simulate thousands of UEs – benchmarking system performance under high-load and failure conditions.

Leveraging Charmed SD-Core, we achieved user plane scaling through Canonical’s Juju charms. Our team is now actively working on control plane scaling, aiming to build a fully elastic and cloud-native 5G core. We have also validated UPF operation in both AF_PACKET and DPDK with SR-IOV modes.

As part of our continued contribution, we proposed our open-source project HEXAeBPF to the LFN 5G Super Blueprint. HEXAeBPF is an interoperable eBPF-defined 5G Core (eDC) Kubernetes operator that enables seamless integration between multiple eBPF-based UPFs (such as eUPF, OAI-UPF-eBPF, BPF-UPF) and open-source 5G core solutions including Aether SD-Core.

Aether, Rakuten Mobile, and Rakuten Symphony Collaborate to Address Key Energy Savings and Traffic Steering Challenges for Heterogeneous Mobile Networks

By Press Release

Research and Development focused on rApps that optimize performance and lower energy costs in heterogeneous 4G/5G radio access networks (RAN)

Palo Alto, California – March 12, 2025 – Aether, a Linux Foundation project, is pleased to announce that it is teaming with Rakuten Mobile and Rakuten Symphony to launch a series of experiments and trials to explore and validate innovative approaches to address RAN energy saving and traffic steering, under its SMaRT-5G initiative. By focusing on energy savings and traffic steering capabilities, network operators can improve efficiency, reduce costs, and enhance user experiences while supporting sustainable practices.

This project is specifically designed for 4G/5G brownfield, heterogeneous network environments utilizing an adapted O-RAN architecture. Open source SMO and Non-RT RIC from Linux Foundation projects, optimized and packaged by Aether, will be used to host the rApps which are foundational for the project. Trials will be conducted within network testing labs of Rakuten Mobile and Rakuten Symphony, with collaboration from Intel Labs, Rimedo Labs, Tietoevry, and VIAVI Solutions, with whom Aether has been conducting a series of proof-of-concept studies in the RAN traffic steering/energy saving space, under its SMaRT-5G program. 

Specifically, the current project will implement and test coordinated traffic steering and energy-saving rApps on an open source SMO/Non-RT RIC stack supported by VIAVI simulator and will progress to a commercial SMO/Non-RT RIC stack of Rakuten Mobile with VIAVI simulator as a precursor to potential field trials.

“Energy Saving and Traffic Steering are two of the most critical challenges facing mobile operators and this effort is a significant step towards applying an O-RAN based solution in an open-source platform environment,” said Sarat Puthenpura, Chief Architect Open RAN, Aether. “It is of significance that this is an rApp play, which uses only an O1 interface without an E2 interface, and the coordination between the energy saving and traffic steering applications will be achieved without an A1 interface unlike conventional approaches, making this a pioneering achievement.” 

Planned contributions as part of experiments and trials:

  • Trials are with rApps, using SMO and Non-RT RIC without Near-RT RIC/xApps. 
  • In the initial phase, open source SMO and Non-RT RIC (from Linux Foundation’s O-RAN Software Community), will be used for experimentation, and later Rakuten’s SMO and Non-RT RIC will be used to replicate and further validate the results. 
  • Initial studies will utilize simulated RAN, and successful experiments will be considered for field trials.
  • Rimedo Labs is developing the Traffic Steering rApp (TS-rApp) that will guarantee UE level performance and coordinate with the Energy Saving rApp (ES-rApp). The TS-rApp to use only an O1 interface and its adaptations, as needed.
  • Intel Labs is creating the AI/ML based Energy Saving  rApp (ES-rApp), implementing optimal cell on/off strategies in coordination with the TS-rApp. The ES-rApp to use only an O1 interface and its adaptations.
  • AI/ML capabilities will be leveraged to optimize the rApps performance.
  • VIAVI Solutions will provide RAN simulation capabilities with its TeraVM AI RAN Scenario Generator that trains ML Models to optimize the RAN and tests the ES rApp against stringent benchmarks
  • Tietoevry will contribute system integration support across O-RAN architecture interfaces, implementation of rApps and all needed adaptations, along with test services, for the lab trials.

“We are pleased to see that the Linux Foundation SMaRT-5G initiative, for which we provide an innovative AI/ML based 5G energy-saving rApp to improve efficiency and performance, will have the opportunity to be tested in collaboration with Aether partners. It is one step closer to be deployed in networks in operation,” said Pranav Mehta, Vice-President, Intel Labs. “Energy savings of 5G systems is a key usage model called for by Open RAN (ORAN) operators and customers.”

“This project provides us with a unique opportunity to apply our extensive expertise in developing advanced RAN algorithms,” said Marcin Dryjanski, CEO, Rimedo Labs. “Traditionally, traffic steering has been a RAN feature that we have delivered in the form of an xApp. In this project, however, we focus on extracting the core algorithm and adapting it for integration into an SMO-level application, expanding its scope and potential impact allowing it to be utilized on legacy networks.” 

“We are excited about the evolving roadmap of the SMaRT-5G initiative and the opportunity to integrate, deploy, and experiment on Energy Saving and Traffic Steering optimizations,”said Mariusz Rudnicki, Wireless Global Business Sales Director, Tietoevry. “This project leverages our deep RAN domain expertise to bring emerging technologies one step closer to real-world deployments. By embedding AI-based solutions we enhance automation, efficiency, and performance – accelerating the path from innovation to operational excellence.” 

“VIAVI are excited to be involved in the SMaRT-5G initiative and use our tools and expertise to ensure the success of the Energy Saving and Traffic Steering optimization experiments and trials,” said Ultan Kelly, Wireless Product Manager, VIAVI. “VIAVI AI RSG creates a RAN digital twin that replicates real-world conditions in the lab enabling x/rApps to be trained, tested and validated in real-world environments prior to field deployment. For over 100 years, VIAVI has been directly involved in testing, assuring and securing the largest communications networks around the globe, and validating network products for all Tier-1 network equipment manufacturers.”

Aether Releases SD-RAN v1.5 Adding Major Enhancements to the RIC and 5G RAN

By Blog

The Aether SD-RAN v1.5 release is the sixth release of the Aether SD-RAN project and adds three major enhancements to the RIC and 5G RAN:

  • xApps updates enabling O-RAN E2SM-RC 
  • Updates to SD-RAN OAI 5G RAN stack to work with SD-RAN RIC
  • Integration of Aether-OnRamp, a blueprint that simplifies SD-RAN deployment

Join us for a techinar March 5th at 8:00 am Pacific to learn about the latest SD-RAN v1.5 release –  Register here.

This release integrates the official O-RAN E2SM RC service model (v1.02.03). The legacy underlying service models PCI, MLB, and MHO xApps from the ONF community E2SMs (including E2SM RC-Pre and MHO) were replaced with the official O-RAN E2SM RC service model. This expands SD-RAN coverage enabling RAN vendors or users/developers to use/test more official O-RAN SM features. With SD-RAN v1.5 release, there are now four use-cases leveraging the official O-RAN SM – KPIMON (with KPM), PCI, MHO, and MLB (with RC). 

The SD-RAN v1.5 release adds support for 5G ONF/OAI 5G RAN stack. Note the previous SD-RAN releases supported the OAI RAN stack option for 4G RAN with the official O-RAN E2SM KPM and the Aether community E2SM RSM service models. The RAN stack now supports the official O-RAN E2SM KPM service model and plans are to support the RSM service model in the future.

The addition of support for the Aether OnRamp blueprint for SD-RAN blueprint provides deployment automation of this SD-RAN release. This more closely aligns SD-RAN with the overall Aether Project which includes other Aether services such as SD-Core, ROC, etc. over the same cluster. We continue to support the sdRan-in-a-Box (RiaB) deployment automation tool, which enables creation of a local Kubernetes cluster and deployment of SD-RAN components on top. However, RiaB is specifically only supported for SD-RAN project deployments only. 

For all the details about this release, please refer to the Aether SD-RAN v1.5 release notes on the wiki.

Aether SMaRT-5G and Rutgers WINLAB Join Forces with the EchoStar-led ORCID Lab on 5G Energy Efficiency Measurements, Modeling and Tests

By Press Release

PALO ALTO, California – January 14, 2025 — Aether SMaRT-5G is pleased to announce that along with Rutgers University WINLAB, it is joining forces with the ORCID Lab to further expand its SMaRT-5G program, broadening the current R&D efforts on 5G energy efficiency measurements, modeling and tests to support EchoStar’s Boost Mobile 5G open RAN network design and ecosystem of commercial vendors.

To accelerate the R&D effort from lab to field, Aether and WINLAB are collaborating with the ORCID lab to expand the experiments to a model of EchoStar’s Boost Mobile production network. This involves refining and validating the energy consumption models on the Boost Mobile Network, testing with commercial RUs, CUs and DUs utilized in Boost Mobile’s network, and prototyping applications to monitor and optimize energy consumption across both the RAN and mobile core. Given that ORCID encompasses both replicas of actual field deployment configurations as well as outdoor sites, this collaboration will validate the results of the current R&D efforts in real-world scenarios.

Improving wireless network energy efficiency not only helps mobile network operators substantially reduce operational costs but is also vital for environmental sustainability. Global telecommunications networks consume a staggering 90 terawatt-hours of electricity annually just to power their RAN. This massive energy footprint equals the entire electricity consumption of metropolitan Los Angeles and generates CO2 emissions equivalent to what major European cities produce in a year. Even a modest 10% reduction in RAN energy consumption would eliminate emissions equivalent to 4.3 million transatlantic flights. As mobile operators worldwide push toward more sustainable operations, optimizing RAN energy efficiency represents one of the most significant opportunities to reduce the industry’s carbon footprint while maintaining the essential connectivity that powers our digital world.

“The collaboration among Aether, WINLAB, and ORCID combines key capabilities and expertise essential to develop and field open RAN technologies”, said Sarat Puthenpura, Chief Architect, Open RAN, Aether and SMaRT-5G. “We believe this will accelerate the adoption and viable commercialization of open RAN architectures by addressing the challenge of RAN energy consumption and management.”

“The collaboration among Aether, WINLAB and ORCID will enable us to further our objectives in providing relevant results to the industry,” said N. K. Shankaranarayanan, Affiliate Research Scientist at WINLAB. ”Measurements from the O-RAN systems and components in the ORCID Lab will allow us to validate our test methodology, refine energy consumption models, and improve energy optimization solutions.”

“ORCID is pleased to partner with WINLAB to provide a production level telecom technology stack to enable new use case testing in both lab and field environments for the advancement of O-RAN,” said Ravinder Jarral, Vice President, Network Development, Boost Mobile.

End-to-end Private 5G demo at the Ubuntu Summit

“At this year’s Ubuntu Summit at The Hague, Netherlands, Canonical gave a live demonstration of how open source with automation can help enterprises in their private mobile network deployments. The demo showcased successful integration of Charmed Aether SD-Core and Charmed OAI RAN, where a 5G PMN was set up with commercial 5G phones connected via a software-defined radio (SDR) as the radio front-end. The demo attracted considerable attention from the Summit attendees, who were particularly drawn by the potential impact of these two products on the private mobile networking market.”

“The demo setup with desktop PCs running a disaggregated 5G private mobile network. Our live installation also showcased the ability to deploy the 5G PMN as disaggregated components. This included the control and user plane separation (CUPS) capability of Charmed Aether SD-Core.”

Aether Nets Canonical Endorsement, Post ONF ‘graduation’

By Blog

Excerpt Published Courtesy of ReTHINK Wireless Watch

“Back in June, Canonical (the firm behind the Ubuntu Linux distribution), released Charmed Aether SD-Core, its implementation of Aether’s SD-Core as a beta release. At this launch, Canonical billed the offering as a way for companies that lack the deep technical expertise of an MNO to deploy a 5G-native network core. — to orchestrate the various microservices needed to keep the network online and in harmony, running on commercial off-the-shelf (COTS) hardware, deployed via K8s.”

“Canonical provided an October update on its Aether-based progress. Next week, at the Ubuntu Summit, a live demonstration of Charmed Aether SD-Core will be running and available for perusal.”

“We are excited about this live demonstration of Charmed Aether SD-Core which combines Aether SD-Core, a scalable open source cloud native mobile core for Private 5G deployments with Canonical’s powerful orchestration engine,” said Larry Peterson, a member of the Aether board and the chair of the Technical Steering Team. “Charmed Aether SD-Core simplifies the operation of a Private 5G, enabling enterprises to efficiently host their own edge applications.”

Build your private 5G network with Charmed Aether SD-Core

By Blog

– Contributed by Canonical –

You might recall that we recently announced the beta release of Charmed Aether SD-Core, bringing automation to the Linux Foundation’s open source 5G software-defined core (SD-Core) networking software. SD-Core is distributed by the Aether project and is for anyone who wants to build a private 5G network. Canonical’s Charmed distribution of this software is designed to simplify deployment and operation of mobile 5G networks. In this blog, we’ll run through the benefits of using charms for your Aether SD-Core deployment.

Aether SD-Core: Open source 5G network core for private 5G

SD-Core is built to be deployed and run as a cloud-native 5G core on Kubernetes. With SD-Core, an enterprise can achieve a private 5G deployment, with premium connectivity available for their devices on-site, instead of relying on traditional local area network solutions. What’s more, as free open source software, SD-Core is cost-efficient, and is trusted by the industry.

5G mobile network core: benefits and challenges

The 3rd Generation Partnership Project (3GPP)’s service-based architecture for 5G core networks provides flexibility, agility and programmability to mobile core networks, transforming a traditionally monolithic software architecture into a fully modular one. This brings efficiency and cost benefits to an operator. Networks can now be deployed on demand, across a distributed cloud infrastructure, and managed with software that can easily scale based on customer demand and dynamic system conditions.

However, as with any cloud-native software, an operator that adopts 5G core technologies requires a suitable set of tools that can flexibly deploy and manage the complex software that 5G core entails. This is because a 5G core network has multiple software components, such as the user plane function (UPF), requiring their own set of configurations and actions to perform software lifecycle management operations. Whilst automation can help manage a cloud-native 5G core with ease, enterprises do not necessarily have the know-how to operate automation software and manage a dozen complex scripts.

What is Charmed Aether SD-Core?

Charmed Aether SD-Core addresses the challenges faced by enterprises that want to deploy and operate their private 5G networks with ease. It provides simple interfaces and removes the need for the necessary know-how on how to operate a private 5G core network. 

Thanks to Canonical’s Juju orchestration engine, it is straightforward to deploy and run a 5G core network. All the complexity is managed by software operators, meaning that an IT admin at an enterprise can deploy and manage it with a simple set of CLI commands and an intuitive graphical user interface. Supported by Canonical’s proven software automation and orchestration engine Juju, which operates a wide range of open source products today, Charmed Aether SD-Core brings simplicity for private 5G for anyone.

Perfect for a diverse set of edge computing use cases powered by a 5G core network

You can deploy Charmed Aether SD-Core as all-in-one on a single Kubernetes cluster, or as a distributed core with its control and user planes running separately on multiple clouds. Such separation enables a central 5G control plane, whereas the user plane is hosted as multiple separate instances at the network’s edge locations. This capability is excellent for an enterprise with multiple sites, each of which benefiting from hosting their own data processing at the edge, for on-site edge computing applications.

See Charmed Aether SD-Core in action at Ubuntu Summit 2024

Charmed Aether SD-Core is fully automated and easily consumable by anyone who has a CNCF compliant Kubernetes running, such as Canonical Kubernetes. At this year’s Ubuntu Summit, we will demonstrate it on COTS hardware on-site, along with a software-defined radio with an open source radio stack. This will showcase how one can leverage open source in telecommunications to build an end to end 5G network on equipment they can run anywhere.

“We are excited about this live demonstration of Charmed Aether SD-Core which combines Aether SD-Core, a scalable open source cloud native mobile core for Private 5G deployments with Canonical’s powerful orchestration engine,” said Larry Peterson, Aether TST Chair. “Charmed Aether SD-Core simplifies the operation of a Private 5G, enabling enterprises to efficiently host their own edge applications.”

Run your private 5G core network at a lower cost

You may be a software developer working on a new application that could benefit from 5G, or a telecom specialist or network engineer building a new system that needs mobile connectivity. You may be a member of technical staff at an enterprise, looking into deploying and testing available open source solutions for a cost-effective private mobile network. 

Whatever your reason for exploring private 5G networks, Charmed Aether SD-Core is a free open source software that is available as beta. We have documentation pages providing you with tutorials and how-to guides that will help you on your way to cloud-native private 5G. You can test Charmed Aether SD-Core with open source radio and user equipment (UE) software simulators already, but check your country’s regulations and see if you can get a shared spectrum license for research and development purposes. Most agencies already support this at a very low cost today.

If you are curious about 5G and would like to test Charmed Aether SD-Core on your own CNCF compliant Kubernetes, such as Canonical Kubernetes, you can deploy and try it today and give us your feedback.

5G Energy Efficiency Metrics, Models and System Tests

By Blog

Check out this article published in RCR Wireless News to for an overview about the Aether SMaRT-5G initiative. This project has been building a series of PoCs that demonstrate progressively advanced energy savings techniques on both Open-RAN and traditional RAN architectures. The phased series of PoCs is to progressively deliver power usage models, APIs and open-source software, with the goal of accelerating MNO adoption and industry impact. The team has demonstrated two SMaRT-5G PoCs in the recent past. The first was at Fyuz in October 2023 and the second took place at the NTIA-hosted RIC forum in March 2024. The key collaborators of these PoCs were Rimedo Labs, Tietoevry, Intel Labs, Viavi Solutions and i14y Labs. More PoCs are on the way.

The National Telecommunications and Information Administration (NTIA)is supporting the SMaRT-5G initiative with a research grant through their Public Wireless Supply Chain Innovation Fund (PWSCIF).
