VQmon's modular software architecture and simple licensing model ensure a custom fit for every environment and application.

  • Easily customizable for specific performance management requirements
  • Supports VoIP, IP video conferencing, streaming video, IPTV, data analysis, or a combination of services
  • License only the features needed for your platform
  • Common APIs for incoming stream/packet analysis and outbound metrics reporting

Analyze performance while keeping content secure.

VQmon is unique in its ability to monitor the quality of encrypted / scrambled video and voice over IP without decryption.

  • Analyzes VoIP and videoconferencing carried over Secure RTP (SRTP)
  • Analyzes TCP streaming video carried over TLS (HTTPS)

Video Streaming

VQmon monitors the quality and performance of video content streamed using key streaming protocols, including HTTP-based adaptive bitrate protocols developed by Adobe, Apple and Microsoft as well as the QUIC protocol developed by Google. It measures both video/audio quality and buffering events, and reports detailed QoE and QoS metrics for each video streaming session.

VQmon analyzes encrypted video streams over HTTPS or QUIC without decrypting them, ensuring the security and privacy of the content while delivering real-time performance insights.

IPTV, Broadcast Media and Studio Production

VQmon integrates seamlessly with IPTV set-top boxes, enabling real-time, continuous quality monitoring and instant performance feedback directly from the customer premises. It supports an extensive array of video formats, including up to 4K (Ultra HD) and frame rates up to 120fps. VQmon's precise Mean Opinion Scores, performance metrics and diagnostics ensure that service and content providers have comprehensive insight into the viewer experience.

VQmon also provides real-time quality analysis for broadcast, live performance and professional media production environments by monitoring high data rate uncompressed video and audio streams (SMPTE 2110) and AV media content transported over IP using Dante.

Voice, Fax and Text over IP

VQmon delivers integrated VoIP/VoLTE call quality analysis to a broad range of devices, including IP phones, gateways, probes and test equipment. It analyzes multiple parallel packet voice streams in real time and provides estimated call quality scores (MOS and R-factor) and comprehensive diagnostics at the end of or during a call. It exports data in diverse formats, such as raw metrics, RTCP XR reports (RFC 3611) and SIP session quality reports (RFC 6035).

VQmon is an indispensable asset for VoIP and network service providers and has been integrated into the products of over 50 equipment manufacturers, including VoIP solutions from Texas Instruments. In addition to Voice over IP, VQmon monitors performance across various other communication methods including Push-to-talk over Cellular (PoC), T.38 Fax over IP (FoIP), and T.140 Real-Time Text (RTT) sessions.

IP Videoconferencing

VQmon is a powerful tool for ensuring high-quality videoconferencing sessions in desktop, mobile and HD telepresence systems. It actively monitors multiple RTP or MPEG-2 video and audio streams and provides real-time assessment of user Quality of Experience through MOS scores and other vital performance metrics.

Accommodating a range of video telephony applications, codecs, and protocols, VQmon supports leading virtual meeting platforms such as Microsoft Teams, Zoom, Google Meet and WebRTC. Its ability to manage encrypted video sessions without the need for decryption ensures that security and privacy are never compromised.

Data Analysis

VQmon integrates network diagnostics, performance, usage and demographics into a single efficient module that can process up to two million packets per second on a single processor core. It captures and analyzes every Ethernet frame and IP packet, supporting a broad range of network protocols including IoT protocols like MQTT and CoAP. VQmon generates metrics and diagnostic data for each packet flow, interface and VLAN in networks with IPv4, IPv6 and stacked VLANs.

VQmon gives network service and content providers crucial insights into user activity and traffic volume for key protocols - such as SIP/SIP over TLS, HTTP/HTTPS, and SMTP/SMTPS - and applications such as YouTube, Facebook, Netflix, or any other site or service identified by IP address or address range.

VQmon Accuracy

VQmon's perceptual quality analysis algorithm has undergone extensive testing to ensure that its estimated quality scores correlate closely to published data derived from subjective user opinion. These charts provide two examples of VQmon's extremely accurate correlation with subjective test data collected from Absolute Category Rating (ACR) tests. (Click a chart to see details.)
