A Modle for Controlled VBR Video Traffic

A novel model for controlled variable bit rate (VBR) video traffic is proposed. The proposed model is built based on the interaction of video coder and video bit stream that is controlled by a rate controller. The model parameters depend on the encoding and rate control parameters and also depend on the properties of video content. The proposed model not only captures the long-range dependent (LRD) and short-range dependent (SRD) properties of video traffic, but also it can include some properties related to the content and the encoding parameters into the synthetic generated video traffic. This is valuable when the synthetic traffic is used for the simulation of network behavior based on content and coder properties. The proposed model has been validated successfully by different methods.
