A Self-Adaptive,Decentralized Replica Location Method
Eng G · Microcomputer Information · 2007
A new SADRL(self-adaptive decentralized replica location method)in data grid is proposed.In SADRL replica location index nodes and replica location nodes are used to accelerate the process of locating multiple replicas of the same data file.Replica location index information are spread evenly on index nodes which can adapt to the joining or departing of index nodes.Replica lo-cation nodes support local query for local replicas.Analysis and experiments show that SADRL can locate the index nodes quickly from the logical file names and gain scalability and good load balance.
