The topology optimization of controlling Hubs in P2P networks

With the improvement of the P2P network traffic proportion accounted for the total flow, P2P networks actually had become an important component of next generation Internet. In P2P network, the existence of Hubs lead to the reducing of the ability of anti-coordinated attack in entire system, and it makes the system become awfully fragile. In this paper, aims to the current phenomenon of the Hubs in P2P network, further studies were conducted. Based on the ideas of the hierarchical processing of the predecessors this paper proposes a modified method based on hierarchical processing, it avoids the conformation of Hubs through optimizing the network topology, reinforcing mechanism is also introduced. The simulations results validate that this method can effectively control the conformation of Hubs, enhance the ability of anti-coordinated attack of P2P network, so it effectively enhances the robustness of the network, and play a role in load balance, improve the utilization of the system.
