This paper puts forward hybrid and hierarchical resource locating model based on Chord (HHRLMC), this model is divided into two layers, the upper layer consisted Super-Peers constructs resource location based on Chord ring, the lower layer adopts centralized scheme with the Super-Peers for center and Pure-Peer for edge. In the process of searching resource, the system can comprehensively use resource directly locating based on Chord and flooding full-text search are two ways to search resource, which expends searching coverage. This paper simulates the model with P2PSim tool and analyzes the performance of the improved model.
