Reverse-Query Mechanism for Contents Delivery Management over Unstructured Overlay Network

It is difficult to build contents delivery platform over the unstructured P2P network because the traffic generated by P2P clients are unmanageable. By applying percolation theory to propagate newly defined reverse-query messages over the unstructured P2P network, we propose novel contents delivery network architecture built over existing unstructured P2P network. We analyzed our algorithm and examined the validity of our model, that will cover more than 80% of all the clients, with relaying reverse-query messages under probability as low as 10%, being effective to reduce the total traffic generated by query propagation. This architecture can be applicable for quasi-broadcast over the Internet. Key-Words: Overlay Network, Percolation Theory, CDN, Power law distribution, Broadcast
