Video over IP has unique challenges as compared to other IPT traffic. IP is used as the transport layer for distributing compressed video content. Both the compressed layer and the IP layer must be properly functioning for the end user to receive video, audio, and meta data. This presentation is a tutorial on understanding the fundamentals of terminology and how the IP layer can impact quality. Packet loss and network burstiness are common problems in Video IP networks. How to isolate the problems and determine corrective action will be the focus of this paper.
