A Distributed Data Stream Management Model Based on Two-tier Overlay Network

In current distributed data stream management models, data should be transmitted on time among many computers through overlay network, which contains only logical topology information. For lack of real topology information, it is hard to control data delay. To solve this important problem, the requirement to process data stream in distributed networks is analyzed in this paper. Chord and super cube structure are introduced to establish a distributed data stream management model, and a constructing strategy about underneath communication is given. This model has the expansibility and robustness of Chord, it also can transmit data quickly using real topology information in super-cube, so it is feasible to QoS control. At last we demonstrate properties of the model using simulation and experiments
