To implement on-demand communication in message distribution system under distributed environment,some architectural design on the tuple space communication based on the improvement of Gelernter’s model is done,and the feature model of Tuple space is defined.Based on the logic of the principle of locality,a space decomposition algorithm is presented.According to difference of matching frequency of different tuple and element in the tuple space,the tuple space is decomposed into a group of buffer subspaces which depend on the abstract relation among the feature spaces,feature tuples and feature elements.When doing the matching operation,the communication process get the matched tuples directly from the buffer subspaces,and the computing cost in a great extent is reduced.
