Spirent Announces Landslide M6 Platform for Validating Next-Generation Mobile Core Networks at Scale

Holmdel, NJ. – March 26, 2026 – Spirent Communications, now part of Keysight Technologies (NYSE: KEYS), today announced the availability of Spirent Landslide C100-M6, the next generation of its market-leading validation platform for mobile core networks. Engineered for the increasingly complex and high-volume traffic demands of 5G Standalone (SA) deployments, AI-driven services, and encrypted traffic at operator scale, Landslide M6 provides the increased performance required to validate and accelerate the next phase of network growth.

As 5G SA networks grow more complex with service-based architectures, testing labs have struggled to keep pace with new traffic patterns generated by network slicing, encrypted signaling, and AI-driven applications. To help operators meet these challenges, the Landslide platform has evolved with the M6 capable of delivering up to 3x faster activation rates than its predecessor, 10x more encrypted traffic capacity, and, for the first time, the ability to handle TLS acceleration.

“The networks our customers are building today look fundamentally different from what they were testing just a few years ago,” says Anil Kollipara, Vice President of Product Management at Spirent. “Now, encrypted traffic is the default, not the exception, and AI workloads are driving signaling patterns no one anticipated, so operators need to know before they go live that their core can handle it. Landslide M6 has been purpose-built to provide the validation foundation needed to support these advanced service rollouts and evolving architectures, while delivering the performance headroom and flexibility network equipment manufacturers need to prepare infrastructure for 6G evolution.”

Landslide M6 is available as both a high-performance hardware appliance and a virtual test server, giving teams flexibility in deployment. It introduces dedicated AI application traffic emulation capabilities, including traffic libraries and workload modeling designed to replicate the behavior of AI and machine learning services on live networks. As operators prepare to support AI-native applications and services, this capability ensures they can validate performance under realistic, next-generation traffic conditions before those services reach subscribers.

Key capabilities of the C100-M6 platform include:

• 6G-ready validation architecture: With 96 processing cores, up to 1 Tbps throughput, 600 Gbps hardware IPsec acceleration, and TLS support, the Landslide M6 provides long-term architectural headroom for emerging standards and 6G preparation.

• AI application traffic emulation: Dedicated AI/ML traffic libraries and workload modeling validate AI-enabled services under realistic conditions, preparing labs for the next generation of network architectures.

• Native 400G and encrypted traffic acceleration (ETA): 400G NIC support and hardware-accelerated IPsec, HTTPS, and TLS processing enable production-realistic, secure core validation at operator scale.

• Flexible control and user plane resource allocation (Flex Mode): Dynamic core allocation lets teams align lab resources to real-world traffic patterns, reducing overprovisioning and making it easier to match the unpredictable mix of signaling and data plane loads that 5G SA and AI traffic create.

• Cloud-ready, Spirent-supplied validation stack: The M6 Virtual ships with a fully configured, Spirent-supported KVM-based virtualization stack, enabling cloud-native deployment with faster scaling, reduced IT dependency, and protection against virtualization cost inflation.

M6 hardware is already being utilized in Tier 1 operator lab environments, with the M6 Virtual test server option providing an additional deployment path for organizations moving toward cloud-aligned and flexible lab strategies. The new platform is backward-compatible with existing Landslide test systems and supports up to 32 test servers managed from a single Landslide Test Manager, allowing customers to scale capacity and throughput as their testing needs grow.
