Validating voice and video quality of service with synthetic monitoring

Validating network quality of service (QoS) requires a synthetic monitoring and traffic emulation solution that can conduct endpoint-to-endpoint and endpoint-to-real-services tests between data centers, cloud services, offices, and remote users. Network operations teams must confirm network communication paths have suitable bandwidth and low jitter / packet loss rates. This is especially true for time-sensitive video and voice over IP (VoIP) services like Zoom and Microsoft Teams / Office 365 — which often use connectionless User Datagram Protocol (UDP) communication.

Measuring VoIP and video QoS requires emulating VoIP and video application traffic across a network via hardware- and software-based endpoints. Conducting endpoint-to-real-service tests measures response times between VoIP / video clients and their cloud- or data center-based management platforms. However, endpoint-to-endpoint tests are also necessary to monitor voice and video performance between users at home or in the office. Tracking key performance indicators (KPIs) such as mean opinion score, loss, delay, jitter, and available bandwidth makes it easier to pinpoint performance degradations and troubleshoot issues.

Network QoS validation solution

Validating network quality of service for VoIP and video applications requires synthetic monitoring and traffic emulation software. Keysight Hawkeye and network endpoints emulate and monitor real-time QoS across cloud-based applications such as Microsoft Teams, Office 365, and Zoom. Capture a range of performance-related KPIs with a library of end-to-end synthetic performance tests and improve troubleshooting with node-to-node traffic analysis.
