Semantic-enabled service discovery aggravating the load of service register and decrease the performance of service matching while increasing the recall and precision of service discovery. To decrease the load of register and the performance of service discovery, a two layered P2P model, is introduced in this article. Based on the model, a service discovery algorithm composed of two stages and three steps is proposed. The model is suitable for open environment with multiple coexistent ontologies. And experimental results show that given appropriate setting, the model makes a tradeoff between recall and responding time during service discovery. In addition, the model decreases the mean load of registers efficiently while holding Recall.
