DVQattest Features & Benefits

Seamless Integration with SQmediator®

DVQattest Agents bring active testing and diagnostics to Telchemy's SQmediator performance management system. Combined with passive monitoring, they provide a comprehensive, uninterrupted view of network performance.

Enterprise-Level Scalability

Efficiently manage up to a million DVQattest Agents from a single dashboard. Extend active testing across diverse and expanding network environments with confidence.

Multi-Platform Compatibility

Use DVQattest Agents across a broad range of devices including desktops, smartphones, servers, routers and VMs. Compatible with Windows, macOS, Linux, and Android/ChromeOS, they adapt to any platform with ease.

Security Assurance

Safeguard your networks and applications with TLS-encrypted tests over remote connections secured by VPN/SASE. Actively validate certificates and ensure robust security.

Simple Deployment via MDM

Easily install and manage DVQattest Agents on end-user devices using standard Mobile Device Management (MDM) or endpoint management tools. Ideal for large organizations with an extensive user base.

Low Resource Utilization

DVQattest Agents operate with minimal impact on memory, CPU, and network throughput. Test and troubleshoot as needed without affecting user experience or system performance.

Comprehensive Testing Suite

DVQattest Agents provide an extensive set of active tests to assess the performance of IP networks, real-time applications and network services. These include VoIP, videoconferencing, DNS, DHCP, HTTP, POP3, SMTP, and SIP tests, all with support for TLS encryption and authentication.

Sophisticated Remote Network Monitoring

Analyze key performance metrics such as bandwidth, latency, and packet loss with DVQattest Agents. Continuously monitor the availability

Precise User QoE Analysis

Proactively monitor VoIP and videoconferencing quality with test calls emulating Zoom, Teams, Webex, Google Meet and other popular real-world services. DVQattest Agents provide detailed QoE metrics, including Mean Opinion Score (MOS), to assess performance and pinpoint problems.

DVQattest Applications

Voice over IP Testing

Easily check VoIP performance anytime, anywhere with DVQattest Agents by placing scheduled or on-demand test calls between any two points in your network. Simulate VoIP calls using various voice codecs and payloads, and get real-time performance feedback - including MOS scores, SIP signaling analysis, and deep diagnostics - to isolate and prevent call quality issues.

IP Videoconferencing Testing

Use DVQattest Agents to seamlessly test and troubleshoot videoconferencing performance across your entire network, from the network core to remote user desktops and mobile devices. Simulate a wide array of real-world video services, including Zoom, Teams, Webex, and Google Meet, using the latest video and audio codecs and display resolutions up to 8K UHD. DVQattest Agents provide precise QoE scores, performance data, and signaling metrics for every video session.

Network, Application & Service Testing

Monitor the security, availability, and response times of your web, email, DNS, DHCP, and other services using DVQattest Agents to perform test transactions with servers over TLS. Measure and troubleshoot network performance with sophisticated path diagnostic tests to any IP address or host name. Run peer-to-peer agent tests to quickly detect and diagnose issues like packet loss, jitter, and delay between any two points in your network.

Frequently Asked Questions

What are DVQattest Agents?
DVQattest Agents are distributed software agents that test and troubleshoot the performance of VoIP, IP video, and network applications and services. They deliver active monitoring capabilities to Telchemy's SQmediator performance management system.
What kinds of tests do DVQattest Agents support?
DVQattest Agents generate test VoIP and video conferencing calls with a range of codecs, payload types and video formats, using integrated VQmon technology to measure voice and video stream quality, signaling performance and overall network health in real time. Additional tests can assess the performance and functionality of network applications and services such as web, email, DHCP and DNS, and identify and diagnose network transport impairments such as packet loss, jitter and delay.
Do I need special hardware to run DVQattest Agents?
No. Agents are pure software applications for Microsoft Windows, macOS, Linux and Android/ChromeOS environments and are not tied to any proprietary vendor platform.
Where can I install DVQattest Agents?
Agents can run on VMs, servers, PCs, and mobile devices, and can be embedded directly into set-top boxes, routers, CPE and other networking equipment. Wherever they are deployed, DVQattest Agents run unobtrusively in the background, ready to execute tests on command.
How many DVQattest Agents do I need?
Depending on the network size and scope, you may need anywhere from a handful of test agents up to hundreds of thousands. There are no restrictions on the number of DVQattest Agents you can install; however, each agent must have a valid license key in order to be used. SQmediator uses a pool licensing model that allows you to install as many agents as you wish, while using a certain portion of those agents at one time.
How do I run tests?
Telchemy's SQmediator is the management tool for DVQattest Agents. In the SQmediator Reporter web user interface, you can easily configure test plans, execute tests and view test results in real time. As an alternative, test agents can interface with third-party management systems via a web services API.
What kind of metrics and diagnostics do DVQattest Agents provide?
Agents report an extensive set of metrics including Mean Opinion Scores reflecting user QoE for voice, video and audio tests, detailed network performance measurements (packet loss, jitter, delay, bandwidth), SIP signaling information, server availability and response time, and more. For a full list of metrics provided by DVQattest Agents for each test type, please contact us.
If I only need some features, do I need to buy everything?
No! Like many Telchemy products, DVQattest Agents are modular software applications designed to let you choose the features and capabilities you need. Support for any combination of VoIP, video conferencing and network testing can be easily enabled or modified on any DVQattest Agent by applying a new pool license key.
Can I use DVQattest Agents for call quality monitoring?
DVQattest Agents are active monitoring tools designed to generate and analyze the performance of test calls. You can easily configure agents to simulate test calls like the ones in your network (i.e., with the same codec, payload type, video resolution and frame rate, etc.), but to monitor the performance of live calls you'll need a passive monitoring tool such as Telchemy's SQprobe. DVQattest Agents and SQprobe are complementary products designed for use with SQmediator as a comprehensive, end-to-end active/passive monitoring solution.
What about future scalability?
DVQattest Agents are a distributed software solution that is inherently scalable. To expand the testing footprint, just deploy additional test agents. DVQattest Agent capabilities, including the number of tests each agent can run concurrently, can be easily modified using license keys.
