Analysis and Modeling of H.264 Unconstrained VBR Video Traffic

In future communication networks, video is expected to represent a large portion of the total traffic, given that especially Variable Bit Rate (VBR) coded video streams, are becoming increasingly popular. Consequently, traffic modeling and characterization of such video services is essential for the efficient traffic control and resource management. Besides, providing an insight of video coding mechanisms, traffic models can be used as a tool for the allocation of network resources, the design of efficient networks for streaming services and the reassurance of specific QoS characteristics to the end users.
