Adaptive Queue-Based Chunk Scheduling for P2P Live Streaming

P2P streaming has been popular and is expected to attract even more users. The challenges for P2P streaming have been on its scalability and video viewing quality. Both require efficient utilization of resources in P2P networks. This paper proposes an adaptive queue-based chunk scheduling method. The proposed scheme can achieve high bandwidth utilization and optimal streaming rate possible in a P2P streaming system. The prototype implementing the queue-based scheduling is developed and used to evaluate the scheme in the real network. The experiment results show the queue-based chunk scheduling method is capable of achieving the streaming rate close to the optimum, and adapting to the peer churns and underlying network dynamics nicely.
