Network testing firm Fluke Networks inserts real-time voice over internet protocol (VoIP) diagnostics and call-by-call Quality of Service into its OptiView Link Analyser and Protocol Expert solutions. Fluke says this allows network managers can now see all levels of VoIP activity on their network, from very broad-based call volume and call quality to individual call channel details. This allows real-time identification, isolation and repair of call quality issues. “VoIP is one of the most mission critical applications being deployed by corporations around the globe,” says Robert Finlay, Fluke Networks product manager. “Yet many IT managers can't check to see if their existing infrastructure will support VoIP, and even fewer have a plan for managing VoIP once it's deployed. Without useful monitoring and troubleshooting solutions like the new versions of OptiView Link Analyser and OptiView Protocol Expert, call quality may cause nothing but user complaints and frustration,” he adds. The VoIP analysis features in OptiView Link Analyser are designed to provide a real-time view of call volume and Quality of Service (QoS) for instantaneous identification of trends leading to call degradation. This enables troubleshooting before end users are impacted. Additionally, this information can be used to track down misconfigurations in network infrastructure. The real-time capabilities provide IT professionals with continuous vision of VoIP call quality in dynamic, changing network environments. The VoIP capabilities in Protocol Expert and Link Analyser make it easy to view VoIP traffic in aggregate, by call or in detail by channel. Fluke says while other protocol analysers provide only VoIP decodes, OptiView Protocol Expert tracks packets on a call-by-call basis while measuring important characteristics, such as jitter, dropped packets, setup and latency. This, combined with an intuitive user interface, makes it easy to access detailed information about call quality and convert these measurements into the most widely used metric for VoIP QoS, a Mean Opinion Score (MOS).
