Flexible testing for applications and networks


  • Comprehensive testing of the 3GPP N2 interface from the 5G gNodeB
  • How do you verify functionality for RCS services for B2B and B2C use cases?
  • Comprehensive testing of N1 interface is essential for validating 5G MM


Flexible, testing for applications and networks

PureLoad is an extremely versatile test solution for applications and networks that offers powerful performance test capabilities. It enables application and service testing from the perspective of client applications and is backed by full-stack implementations.

PureLoad is ideal for testing IP-based applications in mobile networks and CDNs, helping MNOs and content providers to evaluate performance and to support continuous development and DevOps deployment programmes.

It allows functional testing from a single user, but can also scale to millions. As a result, PureLoad is ideal for validating both specific – and complex – scenarios, as well as extreme load testing to model real performance, at scale.

Key features:

  • Full-stack client simulation
  • Scalable load and performance validation
  • Optimised for 5G SBA, RCS, mobile streaming and other IP services
  • HTTP/HTTPS, SIP, Diameter simulation
  • Active monitoring in live networks
  • Continuous testing and DevOps optimised

Extreme Performance Testing – for Realistic Subscriber Behaviour

Testing across your entire subscriber base is essential for validating performance. PureLoad allows realistic simulation of a real subscriber base for key applications. That’s because, instead of using dummy or uniform content payloads, PureLoad enables a diversity of real content, of varying sizes to be sent, for each user. It also enables different sessions to be established, modelling what subscribers really do.

PureLoad offers a full-stack implementation of clients, with control over payload and session, with the scale to extend to 10 million and more unique IP addresses. In live networks, this enables traffic to reach 500,000 HTTP/S transactions per second, with 250,000 new TCP connections/second.

PureLoad is ideal for the continuous emulation of complex service scenarios, supporting rollout and in-service validation and assurance.

RCS and IMS Testing

Easily test IMS, RCS, RBM, MaaP and messaging systems, backed by rich SIP, MSRP, HTTP and Diameter capabilities. Simulate user behaviour and high-volume throughput for both P2P and A2P messaging.

CDN and Streaming Services

Easily simulate streaming service across different networks and devices – from XDSL, FTTH, GPRS, EDGE, UMTS, LTE and 5G SA / NSA. Maintain outstanding customer experience by modelling different performance parameters and criteria, end-to-end.

5G Service-based Architecture

PureLoad simulates traffic from one or more Network Functions, enabling smooth rollout and operation of 5G SBA. Service registration, discovery and security procedures are supported, backed by automation to support continuous delivery and update processes.

5G Core

Test 5G core capabilities such as Network Slicing, DPI and Data Forwarding, with full control over required parameters, such as latency. UE and client traffic simulation enables multiple profiles to be tested simultaneously, with different payloads and traffic behaviours.

Flexible license models

PureLoad is optimised for virtual environments and can be licensed through several simple software models. Operated from an intuitive GUI, new test cases and schedules can be designed, executed and analysed. Easily compare one scenario or test-run with another. Choose from a free, trial version, our Developers’ edition, or the massively scalable Enterprise edition.
