Live Streaming of User Generated Videos: Workload Characterization and Content Delivery Architectures
The authors are recently observing an increase in popularity of Web 2.0 applications offering users the possibility of transmitting their own live streaming media content. The considerable amount of network bandwidth required by such applications, especially at peak usage, poses significant challenges to their scalability and popularity. In this context, they propose and evaluate alternative content distribution solutions that contribute to improve the scalability of this type of system. Their characterization findings are also used to drive the design of a system simulator, used to evaluate the proposed strategies and the traditional architectures, considering different scenarios as well as metrics capturing the interests of both users and service providers.
