A Hierarchical Characterization of a Live Streaming Media Workload

Overview This paper presents what it believes to be the first thorough characterization of live streaming media content delivered over the Internet. The characterization of over 3.5 million requests spanning a 28-day period is done at three increasingly granular levels, corresponding to clients, sessions, and transfers. The findings support two important conclusions. The paper shows that the nature of interactions between users and objects is fundamentally different for live versus stored objects. Access to stored objects is user driven, whereas access to live objects is object driven. This reversal of active/ passive roles of users and objects leads to interesting dualities.
