A novel peer management model for live peer-to-peer streaming

Due to the peer heterogeneity and dynamic, the peer management to construct high quality streaming overlay poses significant challenges in peer-to-peer streaming. In this paper, we propose a fully distributed scheme to achieve optimal peer selection and dynamic peer management, which gains global optimal performance in a highly diverse and dynamic peer-to-peer network. We designed this distributed management model based on an efficient peer selection algorithm and a set of dynamic maintenance scheme. It leverages the performance information and synchronization estimation between peers to select the best peers as senders. With the dynamic peer management protocol, our model is resilient to network dynamic that is characteristic in peer-to-peer networks. The validity and effectiveness of our approach are demonstrated in simulations.
