文摘Frequent joining and withdrawal of resources and services in a grid make dynamic discovery of grid resource and service quite difficult. In this paper, a two-dimensional model of service discovery （TDMSD） is presented for use of dynamic service discovery. Description and proof of the model and the route algorithm of service discovery are proposed. The complexity analysis and simulation results show that the TDMSD model works well.
