Detailed Description

Video application that implements the video traffic model explained in the Annex A of White Paper by the NGMN Alliance. Basically, the video traffic is composed of frames. Each frame of video data arrives at a regular interval T determined by the number of frames per second. Each frame is decomposed into a fixed number of slices, each transmitted as a single packet. The size of these packets/slices is modeled to have a truncated Pareto distribution. The video encoder introduces encoding delay intervals between the packets of a frame. These intervals are modeled by a truncated Pareto distribution. The default configurations of distributions of packet size and packet time assume a source video rate of 64 kbps.
