Abstract: For the large-scale digital content distribution, this study proposes a Hybrid Content Distribution Network (HCDN) model which deploys the CDN system in the backbone networks and builds the P2P regionalization network in the access network. Since the HCDN model can complement the advantages of the CDN and P2P networks, the clients can simultaneously access data through the CDN and P2P networks. Both simulation and analysis results illustrate its advantages over other related networks.
