5 Tips for Optimizing Video Conferencing

Just when you thought you solved Voice over IP quality challenges, along comes video. Like VoIP, video conferencing requires careful attention to latency, jitter and packet loss. However video adds a new wrinkle - demand for lots of bandwidth.

Regardless of research choice or type of endpoint, you’ll need ample bandwidth to support video conferencing. High-definition desktop, room and immersive telepresence systems can eat up from 2 megabits per second to 6Mbps per endpoint.

Application delivery optimization goes beyond simple quality of service, enabling network managers to guarantee sufficient application performance in the distributed and mobile world. Effective delivery encompasses both application availability and performance management. ADO makes it possible to prioritize video traffic flows and compress and/or cache traffic to reduce bandwidth demand. As part of an ADO strategy, evaluate call admission control capabilities to ensure that you allow only the amount of video traffic that your LAN and WAN can support.

Explore some of the new emerging technologies to reduce bandwidth requirements or support high-definition video over less expensive networks just as the Internet. Examples include H.264 Scalable Video Coding, H.264 High Profile, and proprietary codecs from manufacturers just as Microsoft.
