Beschreibung

There has been a phenomenal growth in video applications over the past few years. An accurate traffic model of Variable Bit Rate (VBR) video is necessary for performance evaluation of a network design and for generating synthetic traffic that can be used for benchmarking a network. A large number of models for VBR video traffic have been proposed in the literature for different types of video in the past 20 years. Here, the authors have classified and surveyed these models and have also evaluated the models for H.264 AVC and MVC encoded video and discussed their findings.

Introduction

There has been a phenomenal growth in video applications in the past few years. Today, most viewers receive digital television with high definition services and greater choice of channels. High definition DVDs, Blu-ray discs and video streaming, such as Amazon Instant, Netflix and Hulu, are increasing in popularity. An ever-increasing number of users upload and download videos using sites like YouTube. Recording and sharing of videos using mobile phones is widespread. Video calling over the Internet is commonplace with applications such as Skype and Facetime. Large businesses and organizations use video conferencing applications like Cisco’s TelePresence [TEL] and WebEx [WEB] for face-to-face collaboration across different geographic regions. According to a recent forecasting report by Cisco, all forms of video (TV, video on demand [VoD], Internet, and P2P) will be in the range of 80 to 90 percent of global consumer traffic by 2017. Every second, nearly a million minutes of video content will cross the network in 2017.
