针对数据网格中副本管理这个关键问题,本文提出了一种含超级节点的P2P模型,并在其基础上研究了数据复制的相关策略。使用该模型有效地提高了数据访问的效率和可靠性,并大大减少了维护副本一致性的开销。
Replica management is a key issue in data grids. After presenting a super peers induded P2P model, we studied some related strategies on data replicated. It is shown that the model can effectively improve the efficiency reliability of data access, and that the cost consumption in replica consistency is obviously.
