Performance Analysis of Hybrid Distribution in Human-Centric Multimedia Networking

摘要

With the booming of Human-centric mul-timedia networking (HMN), there are rising amount of human-made multimedia that needs to distribute to con-sumers with higher speed and efficiency. Hybrid distribu-tion of Client/Server (C/S) and Peer-to-Peer (P2P) have been successfully deployed on the Internet and the practi-cal benefits have been widely reported, while its theoretical performance remains unknown for mass data delivery un-fortunately. This paper presents an analytical and experi-mental study on the performance of accelerating large-scale hybrid distribution over the Internet. In particular, this pa-per focuses on the user behavior in HMN and establishes a user behavior model based on the Kermack-McKendrick model in epidemiology. Analytical expressions of average delay in HMN are then derived based on C/S, P2P and hy-brid distribution, respectively. Our simulation shows how to design and deploy a hybrid distribution system of HMN that helps to bridge the gap between system ultilization and quality of service, which provides direct guidance for practical system design.
