Samsung Electronics, Juniper Networks and Wind River have collaborated on a virtual cell site router (vCSR) to allow service providers to operate their networks with end-to-end virtualisation. This software-based network ensures more flexibility, agility, sustainability and faster time-to-market (TTM) for the introduction of new services.
vCSR is part of a new architecture in which the distributed unit and CSR functions coexist as virtualised network elements on one server. In this joint effort, the companies integrated the Juniper Cloud-Native Router, a fully containerised network element, with the Samsung virtualised DU (vDU) on Wind River Studio Cloud Platform. By running multiple network elements on a single virtualised RAN (vRAN) server, the companies are essentially eliminating the need for physical router hardware typically deployed at a cell site and reducing the total cost of ownership (TCO) for network deployments of 5G and beyond.
Compared to traditional networks, this software-based infrastructure offers a more resilient and intelligent mobile network. This development plays a pivotal role in realising the potential of vRAN by fostering flexibility and interoperability among different components. By consolidating multiple software network elements on the same server, operators can benefit from the following:
- End-to-end automation with Samsung’s CognitiV Network Operations Suite: The solution supports plug-and-play deployment, management visibility, and massive software upgrades, delivering a more streamlined and efficient deployment and operation process.
- Greater agility and flexibility: Built on Software-Defined Networking principles, the virtualised architecture enables the greater scalability and flexibility needed to meet operators’ various network configurations and service demands.
- Ability to support diverse applications: With software-centric architecture, vCSR can support security applications such as firewalls and intelligently steer data flows.
- Reduced CapEx thanks to simplified deployment with less hardware: There is no need to purchase legacy hardware since it can be combined within the existing server with the vDU and other software platforms. It also frees up additional rack space.
- Reduced OpEx with energy savings: By eliminating the physical CSR hardware through server consolidation, approximately 30% of energy use can be saved.
“Leveraging our expertise in real-world vRAN deployments, Samsung, along with Juniper and Wind River, are paving the way for end-to-end virtualised networks across the world,” said Ji-Yun Seol, Vice President, Head of Product Strategy, Networks Business at Samsung Electronics. “With this revolutionary approach, we are giving operators the confidence to transform their networks and embrace virtual and open approaches.”
“The compelling objective of vRAN is the flexibility and agility it can bring to operators. Our Cloud-Native Router enables operational simplicity and economic flexibility, while delivering excellent performance. Today’s operators must focus obsessively on the user experiences they are delivering while managing costs, and Juniper’s collaboration with Samsung and Wind River is creating a solution that helps them to amortise 5G investments, build a sustainable infrastructure and create more attractive service offerings,” said Raj Yavatkar, SVP and CTO, Juniper Networks.
“As a leader in the 5G landscape that powers the majority of 5G vRAN/O-RAN deployments with global operators, our Wind River Studio is a purpose-built distributed cloud being used in production, at scale, for vRAN and Open RAN,” said Paul Miller, Chief Technology Officer, Wind River. “In collaboration with Samsung and Juniper, Wind River delivers on the promise of Open RAN, creating a path for substantial TCO reduction and new revenue opportunities for mobile operators.”
This innovative vCSR technology will be demonstrated at Mobile World Congress 2024 at the companies’ respective booths: Samsung (Hall 2, 2M20), Juniper Networks (Hall 2, 2D12) and Wind River (Hall 2, 2F25).
Samsung’s vRAN and Open RAN offer a 100% fully virtualised, cloud-native disaggregated vDU and vCU, proven in the large-scale commercial network deployment across the world. Its industry-leading vRAN software—vRAN 3.0—boasts a range of smart and energy-conserving features optimised to satisfy the forward-looking operators’ needs to build next-generation networks. With its robust ecosystem, Samsung’s virtualised Open RAN brings advanced capabilities that improve performance and increase energy efficiency.
The Juniper Cloud-Native Router takes full advantage of container economics and operational efficiencies, giving service providers the flexibility they need to deploy 5G. The performant, software-based router delivers Juniper’s proven routing technology within the Kubernetes Container Network Interface (CNI) framework. This allows seamless integration with the Samsung vDU on the Wind River Studio platform.
Based on the open source StarlingX project, Wind River Studio provides a fully cloud-native, Kubernetes- and container-based architecture for the development, deployment, operations, and servicing of distributed edge networks at scale. It delivers a foundation to manage a geographically distributed network and simplifies day 1 and day 2 operations by providing a single-pane-of-glass, zero-touch automated solution. Studio addresses service providers’ complex challenge of deploying and managing cloud-native infrastructure for core-to-edge distributed cloud networks to provide traditional RAN performance in a vRAN/Open RAN deployment.
