A High-Bandwidth Live Streaming Model in Mesh-Based Peer-to-Peer Networks

Abstract

Previous works concerning modeling and analysis of mesh-based P2P live streaming mainly focus on the case that the upload bandwidth of ordinary peers is equal to the streaming rate of the streaming server. In this letter, we propose a high-bandwidth P2P live streaming model with two extended streaming schemes. We derive streaming formulas which incorporate multi-peer selection, multi-chunk selection, and heterogeneous streaming modes. We validate our model through simulation, and give in-depth analysis of key parameters.
