In this paper, we propose DRP-DHT, a semi-distributed P2P resource sharing model. This model improves the degree of perception of space and time of the system through double ID identity, enhances the efficiency of query through the multi-layered topology. We apply DRP-DHT to DRPSS, a P2P system that provides both live and time-shifted streams, experimental results show that our DRP-DHT significantly reduces the system's routing delay and maintenance overhead, effectively enhances the service qUality.
