NGN Load Tester

Overview

The Valid8 NGN tester enables testing of SIP, ISUP, Megaco/H.248 and RTP/RTCP.

What we Can Do For You

Tests endpoints, SSE, DHCP server, media gateway (including MRF, c/iBGF options), CO switch

Why we’re 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

Features

Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions and Busy Hour Call Attempts (BHCA)
Check voice, video calls
Registration load
RTP media file playback
Report on media received, call connect time, call duration, jitter, packet loss
Generate valid and invalid/negative messages and call-scenarios
Supports sending invalid responses including malformed, dropped and misordered packets
Alerts and notifications

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. Includes Autom8 Python framework.

Scripting

The application’s subsystems can be edited directly in the browser using TDL. The Message Workshop allows for the creation of test scenarios directly from the hex stream of a remote capture, while the Composer graphical editor (being deployed for all products in 2021) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
