Performance Analysis of MDN Based on P2P Architecture

In this paper, we develop an effective P2P-based multimedia content delivery networks model, which seeks to analyze system performance metrics: hit ratios and throughputs, which are affected by system parameters. We find out that there are three key bottlenecks that affect system performance metrics: the performance of the media content providers, the network bandwidth between nodes and disk I/O bandwidth of nodes. Numerical Analysis of system performance under typical configuration gives the impact of these bottlenecks on system performance. Moreover, the analysis method is also suitable for other P2P-based content delivery networks.
