Abstract

Video traffic accounts for 75% of Internet traffic today. In this paper, we characterize the evolution of a large video streaming service use in Brazil, comparing streaming logs from FIFA’s 2014 and 2018 World Soccer Cups. We report a 166% increase in the average number of unique IP addresses and more than a 300% increase in traffic volume. Arrival rate has also changed and it’s more concentrated at the beginning of the match nowadays. We also compare the impact of QoE metrics on user engagement. For instance, we note that engagement has increased for all bitrate rates and it’s also higher when there are fewer bitrate adaptations. Furthermore, the high rate of rebufferings substantially decreases engagement, but only up to a certain value.
