This post continues our 20 Day Challenge to understand the technical aspects of videoconferencing.
It is important to understand how H.323 traffic impacts the network and then plan for it. Organizations that do not properly go through this process are often disappointed in the quality of their connections and blame the video conference endpoint, when it is really the network. In today’s post, we’ll examine some other tips to make sure that your network is optimized for video conferencing.
Label the ports in the classroom
One easy system that will make life easier for everyone is to label the ports (Internet jacks) in the classroom so that the teacher knows which one to plug the videoconferencing system into. Schools sometimes have jacks that aren’t live, or one of them is specific for the VLAN, or one of them has the special configurations for videoconferencing.
Label the one that teachers or videoconference coordinator should use. This will reduce support calls and keep everyone happier!
Use a wired connection
A wired connection is more stable and secure than wireless. You’ll get a better quality videoconference if you use a hard-wired connection to the Internet vs. wireless. Videoconferencing is more sensitive than regular data traffic. So give the best you have so that the end users will find the quality acceptable!
If you use wireless, then configure it right!
- If your wireless connection is configured to be used solely for videoconferencing, then lock it down to the MAC addresses of the videoconference units.
- If your wireless connection is also used for data, secure it as tight as you can. Avoid scenarios where the other traffic can interfere with the videoconference.
- Make sure your access points on down through to your switches are configured with the correct variables, i.e. duplexing, line speed, bandwidth restrictions or allows, etc.
Find expert assistance
Work with someone who knows about the technical aspects of videoconferencing. Your usual network support personnel may not be familiar with the intricacies of video. Get the advice of a video conference professional as well!
