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.
