Matching algorithm is the crucial factor which influences the performance of Data Distribution Management(DDM) and is an effective way of data filtering.Two new algorithms of sort-based and Rtree-based for DDM data filtering were focused on.Filtering theory of sort-based and Rtree-based matching algorithm was illustrated separately.In the mean time,the sequence list scheme of implementing sort-based algorithm and the framework of implementing Rtree-based algorithm was introduced.Experiments show that Rtree matching algorithm has better performances than sort-based matching algorithm in construction time costs and average searching time costs.
