| Abstract | Live game streaming platforms such as Twitch allow gamers to broadcast their gameplay over the Internet. The popular-ity of these platforms boosts the market of eSport but poses new delivery problems. In this paper, we focus on the im-plementation of adaptive bitrate streaming in massive live game streaming platforms. Based on three months of real data traces from Twitch, we motivate the need for an adop-tion of adaptive bitrate streaming in this platform to reduce the delivery bandwidth cost and to increase QoE of view-ers. We show however that a naive implementation requires the reservation of a large amount of computing resources for transcoding purposes. To address the trade-off between benefits and costs, we formulate a management problem and we design two strategies for deciding which online channels should be delivered by adaptive bitrate streaming. Our eval-uations based on real traces show that these strategies can reduce the overall infrastructure cost by 40 % in comparison to an implementation without adaptive streaming. |
