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 ..."

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 ..."

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 ..."

for VBR video and present an algorithm for generating synthetic traffic. 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

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 ..."

A model for controlled VBR video traffic

by Mehdi Rezaei, Imed Bouazizi - IEEE Int. Con. on Signal Processing and Communications (ICSPC 2007), Dubai, United Arab Emirates (UAE , 2007
"... 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 ..."

Wavelet-Based VBR Video Traffic Smoothing

by Dejian Ye, J. Cam Barker, Zixiang Xiong, Senior Member, Wenwu Zhu, Senior Member
"... Abstract—In a typical video application, such as video-on-de-mand, videos are continuously streamed from a video server to a distributed set of receivers. The constant-quality video compression technique commonly used, variable bit rate (VBR) encoding, produces flows with multiple time-scale rate va ..."

variability, so smoothing the VBR video traffic within an entire distribution tree presents a challenging task. This paper proposes a novel wavelet-based traffic smoothing (WTS) algorithm. Unlike existing algorithms, the WTS algorithm considers traffic smoothing at multiple resolutions. It results in a pruned

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

Effects of Long-Range Dependence of VBR Video Traffic on Queueing Performances

by Do-young Eun, Hee-june Ahn, Byeong-hee Roh, Jae-kyoon Kim - in Proc. GLOBECOM'97 , 1997
"... Previous works related to the self-similarity of VBR video traffic have mainly focused on whether the queueing performances largely depend on LRD or SRD characteristics. In this paper, by correlation matching of input traffic, we show that there is a knee point of buffer size below which the buffer ..."

Multirate Scheduling of VBR Video Traffic in ATM Networks

by Debanjan Saha , Sarit Mukherjee, Satish K. Tripathi , 1997
"... One of the major attractions of Asynchronous Transfer Mode (ATM) networks for transporting bursty video traffic is its ability to exploit the multiplexing gains of packet switching, while providing quality of service guarantees. Unfortunately, most of the multiplexing mechanisms proposed in the l ..."

Applying Multiplexing Characterization to VBR Video Traffic

by Timothy D. Neame, Moshe Zukerman, Ronald G. Addie , 1999
"... This paper reveals a missing factor in the modeling of long range dependent traffic streams. We show that modeling a long range dependent traffic stream by fitting only the mean, variance and Hurst parameter is not possible, and an additional parameter, related to the "level of aggregation" ..."

Introduction Since the discovery of long range dependent (LRD) behaviour in data [1] and VBR video [2] traffic, teletraffic engineers have been searching for a model with a small
