P2P technology has been widely adopted in live streaming system for its scalability and low commercial cost. However, tree based system or mesh based system still has to face the constraint or tradeoff caused by its solo shaped overlay construction. To address this problem, this paper introduces a treemesh based hybrid overlay and an optimized scheduling method. These works have been proven efficient in terms of low control overhead and better streaming experience compared with other systems. All algorithms and methods have been implemented in Anysee2.
