Video Teleconferencing

Achieve Incident-Free Videoconferencing

As airline prices continue to rise, and traveling for meetings becomes less feasible, videoconferencing will continue to become more prevalent. However, any corporate professional or member of the military who has been responsible for providing a quality video teleconferencing (VTC) session for one’s leaders knows the stress that such a meeting can cause.

Some of the more common symptoms of a VTC meeting gone wrong are the eyes that quit blinking because the video has frozen, or conversations beginning to echo as latency issues arise. These are very challenging problems to both predict and resolve.

In order to host a successful videoconference, organizations need to know the answers to the following key questions:

1. What is the health of the particular class of service (QoS/DSCP) that my VTC will be on?

2. Which path has my VTC conference taken on my network?

3. When issues arise, is it because of the network or the VTC application?

These questions can be easily answered by analyzing flow data from existing network devices with Lancope’s StealthWatch System.

StealthWatch provides insight not only into the conversations occurring on the network at any point in time, but also details on DSCP (QoS) class-specific traffic, which will reveal any conversation that may be impacting that all-important video teleconference. Moreover, knowing that there is network congestion isn’t much help if you don’t know which part of the network your VTC conference is traversing. With StealthWatch, determining this information is just a few clicks away. Being aware of any bandwidth issues on the network may mean the difference between a great VTC session and a very unproductive hour.

Finally, with the StealthWatch FlowSensor, the question of whether it is the application or the network causing VTC issues can also be answered. By providing details such as RTT (round trip time) and SRT (server response time), the FlowSensor can quickly pinpoint the source of problems and greatly expedite troubleshooting.

Predicting the success of a videoconference is often a challenge. However, by adding flow collection and analysis to your overall VTC monitoring scheme, you can be much better prepared when the next meeting kicks off.
