Unstructured and structured P2P are two typical distributed models for P2P networking. The unstructured P2P uses flooding method, and has poor scalability and low efficiency, while the structured P2P uses DHT (Distributed Hash Table) method, and has low stability. This paper proposes a two-layer hybrid P2P network - HP2P, which combines flooding and DHT methods: Chord is used for the upper layer and flooding for the lower layer. The general framework of HP2P is presented and its upper and lower layers are described. By analyzing the performance of HP2P, it shows that HP2P has well scalability, high efficiency, and good stability.
