Common Virtual Path and Its Expedience for VBR Video Traffic

The paper deals with utilization of common Virtual Path (VP) for variable bit rate (VBR) video service. Video service is one of the main services for broadband networks. Research is oriented to statistical properties of common and separate VPs. Separate VP means that for each VBR traffic source one VP will be allocated. Common VP means that for multiple VBR sources one common VP is allocated. VBR video traffic source is modeled by discrete Markov chain.
