5G Innovation Spawns New Test Challenges
5G demands are inherently different than 4G, as it aims to address existing and emerging mobile network architecture requirements for consolidated services, greater scale, and lower latency communications.
5G value propositions:
- Scale network resources with the ability to dynamically assign network functions to support new services or new slices serving different verticals or use cases
- Manage costs through consolidated services and paving the way for a true multi-vendor implementation at each layer or function
- Service flexibility with the ability to handle and to accelerate the service delivery to all stakeholders
The 5G Core introduces new protocols, service-based architecture, virtualization, and network slicing, among other things. The elastic nature of the 5G Core network creates new challenges for testing the core network elements, both in isolation and in end-to-end setups.
The 5G architecture is service-based and the interaction between network functions is represented in two ways.
Reference point representation shows the interaction between the NF described by point-to-point reference point (e.g., N4) between any two network functions (e.g., SMF and UPF)
Service-based representation is where network functions (e.g., AMF) within the control plane enable other authorized network functions to access their services.
Validate 5G Core at Scale
Using IxLoad’s real-world subscriber modeling, testers do not need to be protocol experts to develop realistic test scenarios. From a single application, users can perform capacity tests, detail a device’s throughput, measure voice and video quality, and model a wide variety of mobility scenarios.
A multitude of test topologies are available, centered around node isolation, interface testing, or service validation.
- Simulate UE behavior in 5G use case deployments: Network slicing, multi-access edge computing (MEC) low latency and offloading, video optimization
- Scale up to millions of subscribers using stateful application traffic mixes that can interact with real servers and peers
- Perform service quality validation with subscriber modeling, multiplay traffic generation, and quality of experience (QoE) measurements
- Enforce and validate multiple user-plane QoS characteristics per flow or session
- Validate complex scenarios for service-based architectures
- Control test traffic mix and intensity using network objectives to independently manage control- and user-planes
- Validate 5G nodes and interfaces via specialized Ixia hardware or Virtual Edition (VE)
- Generic licensing scheme offers flexibility to grow with your needs and fit your budget; future-proof and pay-as-you-grow, protecting initial investment
