Replica Placement Strategy Based on Education Resource Grid
Liu Fang-ai · Jisuanji gongcheng · 2008
Replica mechanism is the efficient method of improving grid performances and reducing client delay. Replica placement strategy is the key problem of replica mechanism. This paper introduces the architecture of education resource grid. According to the architecture, it presents three dynamic replica location strategies, optimizes three strategies from different aspects, and reduces client delay on the premise of keeping the storage space of replica. Experimental results show that strategies are effective.
