We have seen a phenomenal growth in video applications in the past few years. An accurate
traffic model of VBR video is necessary for performance evaluation of a network design and …

This paper presents a source model for VBR video traffic. A finite-state Markov chain is
shown to accurately model one-and two-layer video of all activity levels on a per source …

MPEG encoded video accounts for a considerable share of high-volume traffic in both
wireline and wireless networks of the next generation. MPEG video requires high bandwidth …

We propose models for variable bit rate (VBR) video traffic that allow for different frame types
present in the video, different activity levels of different frames and a variable group of …

All traffic models for MPEG-like encoded variable bit rate (VBR) video can be broadly
categorized into (1) data-rate models (DRMs) and (2) frame-size models (FSMs). Almost all …

To facilitate network performance analysis and simulations for IPTV traffic, a two-level
Markovian traffic model is proposed in the paper. The model considers both spatial and …

Video streaming and conferencing are expected to be the major services in future
communication systems. The design of communication systems to support high-quality video …

The performance evaluation of broadband networks requires statistical analysis and
modeling of the actual network traffic. Since multimedia services, and especially variable bit …

Video conferencing is an important application that has been extensively used in IP, ATM
networks, and TV broadcasting as a means of interactive communications. Teleconferencing …

The efficient transportation of real-time variable bit rate (VBR) video traffic in high-speed
networks has been an area of active research. The VBR video traffic characteristics having …
