ProLab H323 Test Solution

With the ProLab H.323 Testing solution, developers and network administrators can emulate and test entire network systems prior to deployment and evaluate end user service problems. These include advanced test call emulation, gatekeeper simulation, media analysis, voice and video quality, such as analyzing packet or frame loss, delay, and jitter checking. In addition, the ProLab H.323 Testing Solution simulates different network topologies and validates performance of H.323 networks and media quality.

Spirent’s ProLab H.323 Testing Solution includes HD and SD simulation and Video Quality analysis

ProLab H.323 Testing - Spirent

ProLab H.323 Testing Solution encompasses a wide range of testing tools for several environments and includes the following add-ons:

Terminal Simulation

Performs advanced simulation by generating signaling and media. By generating calls, the ProLab Testing Suite performs a variety of tests, including protocol and stress tests.

Gatekeeper Simulation

Provides full gatekeeper application with option to simulate atypical responses according to the standard.

Analysis & Report

The ProLab Test Results Analysis Solution offers an intuitive tool to automate testing and results analysis and flexible report generation that can be customized to specific requirements.

Voice Quality

ProLab is equipped with both MOS and PESQ (Perceptual Evaluation of Speech Quality) voice quality tools.

Video Quality

The Video Quality measurement uses different video metrics. It intrusively analyzes received video streams and perceptually scores relevant degradations on a 5-point MOS scale. Additional key performance indicators (KPIs) are output to allow experts to perform more detailed analysis.
