Abstract: Distributed service composition system is widely used in military, communication and other fields.In order to reveal the system’s characteristics, a bipartite network model is proposed. The relation of sever-node’s degree distribution to the three factors of terminal-node’s expectation, terminal-node’s task load andlocal-world size is analyzed by the mean-field theory undercondition ofload balancing and random selection. Both numerical analysis and simulation results show that local-world and sever-node’s degree distribution are irrelevant with random selection.

Key words: bipartite network, distributed service composition, the mean-field theory, load-balance
