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… (More)
