Because of the dynamic and complex gridenvironment, the speed and stability of grid data transfercan’t be guaranteed, which has become the “bottleneck”that restricts grid applications,Replica is also very hard toincarnate advantage. Multi-Agent, with virtue of savingnetwork bandwidth, realizing load and uninstall, increasingapplication’s, and affording , can solve problems in thetransfer process primely. However, they are the key factorsthat multi-replica transfer task is transformed into multiagentcoalition formation, and the coalition formationtactic.This paper analyzes and researches the relationshipbetween replica transmission and Multi-Agent coalition,puts forward a high efficient coalition formation tacticbased on linear programming optimization methods ofmathematical theory.
