Telchemy Releases DVQattest Version 2.0 - New Active Test Tool for VoIP, Videoconferencing, and Network Test

November 21, 2011

DVQattest Version 2.0 is a new active test system for unified communications. DVQattest generates Voice over IP and Videoconferencing calls with SIP signaling, synthetic HTTP, POP3, SMTP, DNS and DHCP transactions and a range of IP network tests. This advanced test product supports pre-deployment testing, SLA monitoring and troubleshooting for converged networks and services.

DVQattest Agents are compact but highly featured software applications that can be installed on a range of operating systems and hardware platforms, including Linux servers and appliances, Android mobile phones and directly integrated into network equipment and CPE. Tests can be run on-demand or scheduled to run indefinitely. Agents can run multiple concurrent tests to other Agents or to IP phones, Web sites, Email sites and other network-based services. DVQattest Agents support complex networks with overlapping IP address spaces, VLANs and a range of SIP infrastructure configurations.

VoIP and Videoconferencing tests verify the performance of both SIP signaling and the media stream. Voice and Video quality is measured using Telchemy's market-leading VQmon technology, providing MOS scores and a wide range of diagnostic data. Voice over IP tests support configurable codec, packet size and jitter buffer configuration; Videoconferencing tests support configuration of codec, image size, GoP, frame rate, bit rate and smoothing.

Network tests include Agent-to-Agent tests that measure loss, jitter and available bandwidth in each direction, industry standard network tests and advanced route diagnostics. DHCP and DNS tests verify correct operation of vital network functions and HTTP/POP3/SMTP tests measure performance of key applications.

The DVQattest Controller provides an easy-to-use management application that supports test definition, remote DVQattest Agent management and test result collection and reporting. For larger networks, the SQmediator performance management application provides a scalable and intuitive solution for multiple concurrent users. DVQattest Controller and SQmediator support key security requirements and maintain AES encrypted connections to DVQattest Agents.

DVQattest provides dependable, accurate and detailed performance metrics and has already been deployed in critical network applications. When the US Department of Defense needed accurate tools for measuring performance for Internet Routing in Space (IRIS) satellite based router project, DVQattest provided a key element of their measurement infrastructure.

DVQattest is available in a wide range of configurations, suitable for mid-large enterprise, hosted and cloud based services and tier one service providers.
