The vast majority of video conferencing products now support the use of IP networks for transport. The networks are theoretically ready to handle the video traffic seamlessly, but enterprises implementing IP Video Conferencing (IPVC) often find that performance is poor. Choppy video, pixilation, out of sync audio, and intermittent black screens are a few of the symptoms of improper network design.
This research note addresses the three key network considerations when deploying IPVC, including:
- Selecting video protocols and forecasting bandwidth requirements.
- LAN design and Quality of Service (QoS).
- Ensuring the WAN can support and prioritize video traffic.
Enterprises that prepare the network for an IPVC implementation are likely to succeed, while those that do not will almost certainly experience difficulties.
