Assessing the Quality of Experience of SopCast
article
Recently, there has been a growing interest in academic and commercial environments
for live streaming using P2P technology. A number of new P2P digital Television (P2PTV)
applications have emerged. Such P2PTV applications are developed with proprietary
technologies. Their traffic characteristics and the Quality of Experience (QoE) provided by them
are not well known. Therefore, investigating their mechanisms, analysing their performance,
and measuring their quality are important objectives for researchers, developers and end
users. In this paper, we present results from a measurement study of a BitTorrent-like P2PTV
application called SopCast, using both objective and subjective measurement technologies. The
results obtained in our study reveal the characteristics and important design issues of SopCast,
as well as the QoE that the end users perceive.
