Fluke Networks Visual finds a 'TruView' of Voice over IP

The success of unified communications (UC) hinges on your users’ happiness. That “happiness” is otherwise measured by what the IT industry calls Quality of Experience (QoE) — a metric not easily obtained.

With Voice over IP (VoIP), for example, many factors influence the quality of a call. Finding the culprit can be a daunting task. Today, there are many tools, both free and costly, that help network engineers and managers find out what’s going on with the network: Quality of Service (QoS) tools, packet sniffers, network analyzers — the list is vast.

Fluke Networks Visual — the performance management brand of Fluke Networks — added to this list with it’s TruView announcement this week. Unlike other network monitoring solutions, the product enables network engineers to troubleshoot an application performance issue within three or four clicks of a mouse. TruView shows both packet and flow-based views of network and application performance. The depth and breadth of application performance monitoring (APM) coupled with the ability to troubleshoot network problems not only consolidates tools, but helps IT solve service quality issues more quickly.  

The TruView tool can monitor all network traffic except for video (which is in the works), but Fluke Networks Visual Vice President Daryle DeBalski calls out VoIP monitoring specifically “because it’s so important in today’s business world…. Almost all of our customers use [VoIP].”

DeBalski said in a phone call that TruView can analyze VoIP traffic in realtime because its appliance stores all the packets and calls: “We can re-construct an audio call so [network enginners] can hear what the user heard.”

While other vendors store these packets, Debalski says the TruView appliance “does it in one place unlike anybody else.” It works with 1 and 10 gigs of data streams and generally saves two weeks of packet calls and application traffic unless their customer has specialized needs.

Rather than having to measure network traffic from weeks ago, the appliance is also smart enough to calculate baselines to let IT know what’s considered “good” performance on a typical Monday morning.

Ultimately, fixing “the network is slow” problems is what TruView is designed to do. While other tools may give you a bell or alarm to let you know something is wrong, a “true view” of network traffic can make that user experience all the happier.
