Abstract:
Current commercial live video streaming systems are based either on a typical client-server (cloud) or on a peer-to-peer (P2P) architecture. The former is preferred for stability and QoS while the latter is scalable with small bandwidth and management cost. In this paper, we propose a scalable and stable service management architecture for a cloud assisted P2P live streaming system. In order to achieve this we develop an analytical model and a hybrid control strategy that dynamically allocates from the cloud the exact amount of bandwidth that is required while simultaneously dynamically adapts the playback rate to the available bandwidth resources in order to guarantee the complete and on time stream distribution. To the best of our knowledge our proposed model is the first that copes up with a hybrid control strategy for simultaneous playback rate adaptation and auxiliary bandwidth allocation.
