Abstract:
In a P2P-based video on demand (P2P-VoD) streaming system, the load of nodes is one of the most important influencing factors for system performance. On one hand, some nodes may receive a lot of requests which may result in overload. On the other hand, the other some nodes may receive too few requests, leading to low utilization. Therefore, designing an effective load balancing strategy is crucial for system performance promotion. Existing researches handle this issue by considering node status in the past period of time, not concerning the potential load of nodes in the future. In this paper, we propose a load balancing strategy based on request queue (RQLB) for P2P-VoD system. Specifically, we firstly define the priority of the request by considering urgency, scarcity and the playing smoothness factors, making the high priority requests be handled in time. Subsequently, by considering the upload bandwidth, reliability and load degree, we define the utilization function of the node, so that the relatively low priority requests will be transferred to nodes with low utilization and reliability. Simulation results show that our proposed strategy can effectively solve existing load imbalancing problem in the P2P-VoD system, enhancing user watching quality.
