Minimizing streaming delay in homogeneous peer-to-peer networks

Abstract

Two questions on the theory of content distribution capacity are addressed in this paper: What is the worst user delay performance bound in a chunk-based P2P streaming systems under peer fanout degree constraint? Can we achieve both the minimum delay and the maximum streaming rate simultaneously? In the homogeneous user scenario, we propose a tree-based algorithm called Inverse Waterfilling, which schedules the chunk transmission following an optimal transmitting structure, under fanout degree bound. We show that the algorithm guarantees the delay bound for each chunk of the stream and maintains the maximum streaming rate at the same time.
