• Combining the international newest research result of multicast tree , this paper get a series of high efficiency arithmetic of multicast tree problem with the method of increasing storage space , and this paper also takes into account the dynamic capability of arithmetic . in many research fields of multicast tree , many high - efficiency solutions were obtained in this paper . this paper has broadly discussed about multicast tree problem and obtained dmdt ( dynamic minimum distance tree ) , fmph ( fast minimum path cost heuristic ) , dmph ( dynamic minimum path cost heuristic ) and fgmra ( fast group multicast routing arithmetic )
