AbstractThe performance of optical switched networks (OSN) to support video traffic with scaling characteristics and different QoS requirements is studied in this paper. The and fBm processes are considered to model the video input traffic. These processes are examined in terms of its video traffic scaling (H), heavy-tail distribution (HTD) and autocorrelation (ACF) characterization. A new frame-to-burst (FTB) assembly is proposed to enable the optical edge-switches to deal with video traffic. We demonstrate that video traffic tail distribution is more critical to the optical switch dimensioning and thus OSN performance than the scaling characteristics.
