Matching method for data in distributed interactive simulation system

The invention provides a matching method for data in a distributed interactive simulation system. In the method, after simulation nodes receive newly-released subscription conditions, the subscription conditions are inserted into a multi-index structure in accordance with predicates of the subscription conditions, and the subscription conditions are inserted into mode relationship sets in accordance with modes of the subscription conditions. After the simulation nodes receive newly-released simulation data, according to each attribute in the simulation data, all unsuccessfully-matched predicates related to each attribute are searched in the multi-index structure, and subscription conditions belonging to the predicates are set to unsuccessful matching; and all mode sets identical with or covered by simulation data modes are searched in the mode relationship sets, the subscription conditions related to the sets are traversed in sequence, and all matched subscription conditions are obtained finally.
