Abstract
We propose a two-layer hybrid P2P network (HP2P), in which the upper layer is structured Chord network, and the lower layer is unstructured flooding network. HP2P benefits from the advantages of both structured and unstructured networks and significantly improves the performance such as stability, scalability and lookup latency of the network. In this paper, the Chord overlay algorithm is formalized. The data structure, node joining, node leaving, routing table stabilizing and lookup services are introduced in detail. Further the caching mechanism is employed to accelerate lookup services. In particular, the analysis shows that the stability of Chord overlay in HP2P network has been enhanced indeed.
