Per formance Evaluation for Multicasting Video over OpenFlow-based Small-scale Network

Abstract

When demand for transmitting multimedia data increases, network congestion is more likely to occurand users will suffer high loss rate as well as high delay. In order to enhance quality-of-service (QoS)of video multicasting, we need to raise transmission reliability and reduce end-to-end delay. This paperproposes a routing mechanism for a OpenFlow-based small-scale network in order to multicast videoreliably with low delay. In our method, multipath routing will be applied to Multiple Description (MD)Coded video to exploit its multi-description property. Through performance evaluation, our method showsimprovement on loss rate, delay and video distortion.
