DHT-Based Cross-Transmission Protocol Peer-to-Peer Resource Sharing Model

In this paper, a DHT-based cross-transmission protocol P2P resource sharing model is proposed to address the interconnection and intercommunication problem in P2P systems, where the DHT network stores the resource information for each P2P system. Peer in the model can participate in multi P2P systems, intelligently finding out the same resources among them. Through parallel downloading file from multi P2P systems, the model can provide essential functions to original system, such as reducing user response latency, minimizing file download time and providing Quality of Services (QoS) guarantees. Simulation results demonstrate that the model has better system robustness, scalability and user experience compared with current P2P systems.
