Landslide Core Network Testing

As 5G networks grow in scale and complexity, service providers face increasing pressure to deliver reliability, flexibility, and performance in the face of constant change. In this on-demand webinar, Gabriel Brown, Senior Principal Analyst at Heavy Reading, and Bill Clark, Principal Product Manager, for 5G cloud native deployment validation at Spirent, unpack what it truly means to build a resilient 5G infrastructure in the era of cloud-native network functions (CNFs). The discussion explores how CNFs—built on microservices, containerization, and Kubernetes-based orchestration—are redefining resilience. Rather than trying to eliminate every possible failure, today’s networks are designed to expect them. The focus has shifted toward rapid recovery, self-healing behaviors, and intelligent automation that ensures services like autonomous vehicles, industrial IoT, and low-latency applications continue to run without disruption—even under pressure.

As operators accelerate the shift to cloud native architectures, the complexity of 5G deployment grows exponentially. In this in-depth RCR Wireless editorial webinar, Spirent and industry leaders look at opportunities, and challenges associated with this transition to cloud-native architecture. They bring clarity to one of the most significant transformations telcos face today. Focused on the cloud native journey, this session is packed with real-world insights, practical considerations, and lessons learned from extensive experience validating cloud native 5G deployments across the industry. The session explores the evolution from legacy physical infrastructure to virtualized network functions, and now to fully cloud native network functions (CNFs). It unpacks the core components of a cloud native environment, including Kubernetes orchestration, containerization, and service-based architecture, and explains why these elements are essential for achieving scalability, agility, and resiliency in next-gen networks.

The Lab-to-Live white paper, produced in partnership with Appledore Research, explores the critical shift required for modern networks to adopt a seamless testing and deployment approach. As cloud-native networks become central to enabling scalable, resilient, and agile infrastructure, traditional testing methods can no longer keep up. Lab-to-Live is a holistic strategy that integrates lab testing, network deployment, and operational monitoring into a unified lifecycle, fostering continuous improvement and stronger collaboration across development and operations. __Key takeaways__ from this research emphasize the importance of agile testing environments and proactive monitoring for cloud-native network resilience. With networks increasingly defined by software-driven applications, ensuring reliability involves rapid fault recovery and a shift from hardware-based resilience to software-based fault tolerance. This approach leverages continuous testing and visibility across all network components to proactively address failures, optimize resource usage, and support multi-vendor environments.

As 5G technology continues to evolve, the challenge of ensuring that cloud-native network functions (CNFs) operate reliably in distributed environments becomes increasingly critical. With the complex architecture of 5G standalone networks, it’s essential to anticipate failures before they occur—and recover automatically without disrupting service. Kubernetes auto-healing capabilities provide a path forward, but CNFs themselves are designed to fail, making the resiliency of your network more important than ever. In our whitepaper, __How 5G CNFs Are Designed to Fail__, we explore the core concepts behind building resilient 5G CNFs within Kubernetes environments. Learn how to prepare for inevitable system failures and maintain service continuity even in the most challenging real-world scenarios.

Service providers expect 5G to help power critical business transformation by diversifying and growing revenue streams. The right strategy will support rollout of new services in weeks versus months, with always-on, high-performance, and expansive coverage attracting and delighting customers.

This whitepaper details a case study of how Telefónica uses Landslide to deliver enhanced automation with a 3x faster test and assurance process for ensured performance of 5G private networks.

We’ve entered the era of 5G, with blazingly fast speeds, vast coverage density, large area traffic capacity, and super low latency. 5G is more than a step up from 4G; it’s a radical leap that dramatically improves mobile broadband services and empowers the Internet of Things (IoT) by enabling connectivity to billions of global devices. Most providers are taking an evolutionary approach to 5G, starting with 4G evolved pack core (EPC) control / user plane separation (CUPS), then migrating to 5G non-standalone (NSA), and finally deploying full native 5G or adopting Open RAN (O-RAN). Assuring a successful journey from 4G to native 5G requires the ability to test and assure every phase of the journey and every stage of the service lifecycle. Spirent solutions test and assure your evolution to 5G across the service lifecycle — from the lab to the production network.

With demand for 5G growing across South Korea, operators are moving quickly to augment their non-standalone (NSA) and standalone (SA) capabilities. But ensuring reliability, maximum availability, and high-performance connectivity amplifies the need for rigorous testing before deploying new systems. To enable a more versatile, competitive 5G network, a leading Korean wireless operator sought to expand its network infrastructure. A global communication technology provider was positioned to deliver a 5G NSA platform as a Proof of Concept (PoC), which, if successful, would lead to both NSA and SA implementations. However, testing of the NSA system proved challenging using the operator’s existing test suite. Spirent partner ERK Solution Co. teamed with the technology provider to define and deliver a solution that could meet the operator’s stringent performance demands.
