Diameter load tester S6t interface test solution


S6t interface is between the SCEF and HSS. The S6t interface test solution from Valid8 enables conformance or load testing of this interface,

What It Can Do For You

Tests the S6t interface.

Why It’s Different

  • Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
  • Web-based UI is easy to learn
  • HTTP API enable integration with automation test systems and other equipment
  • Stateful modeling provides accurate emulation of network elements



  • Configuration Information Requests/Answers
  • Reporting-Information Requests/Answers
  • Non IP Data Delivery(NIDD)-Information Requests/Answers
Configurable Parameters
  • ‍Call session length
  • Concurrent calls/endpoints

Automation API

User commands can be fully automated using REST API. This includes performing all test control functions as well as collecting results and metrics. It can be integrated into virtually any CI system via the HTTP API, including Jenkins, CircleCI, Gitlab and others.


The application’s subsystems can be edited directly in the browser using TDL or by using the graphical tools. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor (on the feature roadmap for 1Q 2020) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
