Network Testing Tools
Network IP traffic packet generators are used for network performance testing under maximum or partial throughput conditions. Network health can be analyzed by network traffic measurement in a testbed network, using an IP network traffic generator such as IP Traffic Test and Measure. The traffic generator sends packets, often with a unique packet identifier, making it possible to keep track of the packet delivery in the network.Network impairment simulation (emulation) is a technique for testing the performance of real applications over a virtual network. The aim is to assess performance, predict the impact of change, analyze impairment conditions or otherwise optimize technology decision-making. Measurements usually focus on simulation of conditions like delay, jitter, latency, dropped packets and limited bandwidth.

Non-Intrusive voice Quality Analyzer
NIQA
The most known methods for quality evaluation of voice transmission systems were developed by Telecommunication Standardization Sector of International Telecommunications Union (ITU-T) in the middle of 90-s. Results of this work are presented in Recommendation P.800 (P.830) «Methods for subjective determination of transmission quality» [1, 2]. This document describes conditions for voice quality testing, audio contents, scoring and methods to evaluate results. Typically “Methods for subjective determination of transmission quality” are used to obtain mean subjective quality score according to five-digit scale (Mean Opinion Score – MOS).
