Portland, Ore. Designed to test voice over Internet protocol (VoIP) over WLAN systems, the VeriWave Analysis Test Suite assesses voice quality metrics of real-world networks. It analyzes traffic prioritization, evaluates the network behavior in the presence of non-voice traffic, and measures overall call quality when users roam between WLAN access points. The test suite provides open-air testing of mixed voice/data networks and supports various handsets to generate voice traffic, scaling the network capacity from one handset to the maximum number supported by the network before voice quality degrades below acceptable levels. The test suite also evaluates mixed-use networks by introducing controlled data traffic to the networks. In addition to creating the base-line quality measurements, the test suite adds background data traffic to precisely evaluate how the wireless network handles voice call prioritization in the presence of precisely controlled data traffic. The VoIP over WLAN Analysis Test Suite and the WaveTest Traffic Generator/Performance Analyzer are available now. WaveTest pricing starts at $28,995.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
