Internet Protocol is essential to support video infrastructures now and in the future. IP is absolutely the wave of the future.
Assuming you're using video for collaboration and conferencing, the most important step when working with video is to look at the health of your network. IP allows for the retransmission of data; and unless something is really wrong -- like a bad network interface card or bad cable -- you normally won't notice the retransmissions. However, with video infrastructure, the retransmissions become visual and audible with pixilation and audio issues.
A network analyzer can determine if you're experiencing retransmissions and make sure the ports are running at the speed you predicted for your video infrastructure. Beyond that, you'll want to plan for the increased bandwidth demands that will occur when video collaboration comes onto the network.
With video collaboration, for part of the session, the Ethernet traffic is not as bursty as it is for file transfers alone. Remember, it's not how often a network resource is used, it's how fast and reliable it is when in use. Therefore, port utilization is a poor indicator of how well your network will support real-time communications, such as voice and video.
Another consideration for video infrastructure is the amount of storage you want to provide and the period of time you may store the video. This is going to vary greatly, depending on the equipment you use, the level of video compression you find acceptable and the amount of video you wish to store. The good news is video storage is relatively inexpensive these days.
