Methods for performance evaluation of VBR video traffic models

by David M Lucantoni , Member, IEEE Marcel F Neuts , Member, IEEE Amy R Reibman - IEEE/ACM Transactions on Networking , 1994
"... Abstract-Models for predicting the performance of multiplexed variable bit rate video sources are important for engineering a network. However, models of a single source are also important for parameter negotiations and call admittance algorithms. In this paper we propose to model a single video so ..."

of performance that we want to predict from the model; see e.g., [6]. In this paper, we propose two criteria for judging the appropriateness of a traffic model for bursty services. The first one applies to any high speed bursty data service and the second is specific to a variable-bit-rate (VBR) video

Performance Evaluation of VBR Video Traffic Models

by Lakshmi Yellanki , 1999
"... Variable bit rate (VBR) video is expected to become one of the major applications used on high-speed networks such as ATM-based B-ISDN. Effective design and performance analysis of such networks thus depends on accurate modeling of VBR video traffic. Traditionally, Markovian models which exhibit sh ..."

by Savera Tanwir, Harry Perros
"... Abstract—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 also for creating synthetic loads that can be used for benchmarking a network. In view of this, various models ..."

Content-based VBR Video Traffic Modeling and its Application to Dynamic Network Resource Allocation

by Paul Bocheck, Shih-fu Chang , 1997
"... In bandwidth limited networks and network interfaces, dynamic resource allocation can substantially increase the link utilization and also decrease the required network buffering. In general, there are two important tradeoffs effecting the network utilization. First, tradeoff between efficiency o ..."

of the real-time dynamic resource allocation and the policy controlling the renegotiation frequency. Second, tradeoff between accuracy of stream resource prediction and prediction delay. The latter is the focus of our work. We propose a new Content-based Video Traffic Model which uses the visual content

Analysis, Modeling and Generation of Self-Similar VBR Video Traffic

by Mark Garrett, Walter Willinger , 1994
"... We present a detailed statistical analysis of a 2-hour long empirical sample of VBR video. The sample was obtained by applying a simple intraframe video compression code to an action movie. The main findings of our analysis are (1) the tail behavior of the marginal bandwidth distribution can be accu ..."

Trace-driven simulations show that statistical multiplexing results in significant bandwidth efficiency even when long-range dependence is present. Simulations of our source model show long-range dependence and heavy-tailed marginals

A Content Based Approach to VBR Video Source Modeling

by Paul Bocheck, Shih-fu Chang - IEEE 6th International Workshop on Network and Operating Systems Support for Digital Audio and Video , 1996
"... We are presenting a new framework of content based video (CBV) modeling, suitable for scalable variable bit rate (VBR) video traffic. Our approach differs form previous works in that it is not based only on matching of various statistics of the original source, but rather it includes characterizatio ..."

Characterization and modeling of VBR video traffic

by E. Casilari, A. Reyes, A. Díaz-estrella - Electronic Letters
"... In this letter we analyse the impact of VBR video traffic characteristics on broadband network performance. In particular, we compare in a queue the behaviour of several models that adjust different statistical parameters of two real MPEG traces. We prove that a good fit of the probability density f ..."

Generating antipersistent VBR video traffic

by Mehdi Rezaei, Imed Bouazizi, Moncef Gabbouj
"... A novel model for antipersistent variable bit rate (VBR) video traffic is proposed. Antipersistent VBR video bit streams are a subset of VBR video bit streams in which the bit rate is controlled by a rate controller when the video is encoded. Statistical properties of antipersistent VBR video bit st ..."

"... MPEG video traffic is expected to cause several problems in ATM networks, both from performance and from architectural viewpoint. For the solution of these difficulties, appropriate video traffic models are needed. A detailed statistical analysis of newly generated long MPEG encoded video sequences ..."
