A GA-Based Replica Placement Mechanism for Data Grid
Data Grid is an infrastructure that manages huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. To increase resource availability and to ease resource sharing in such environment, there is a need for replication services. Data replication is one of the methods used to improve the performance of data access in distributed sys...
متن کاملA Survey for Replica Placement Techniques in Data Grid Environment
In data grids, data replication on variant nodes can change some problems such as response time and availability. Also, in data replication, there are some challenges to finding the best replica efficiently in relation to performance and location of physical storage systems. In this paper, various replica placement strategies are discussed. These replica placement strategies are available in th...
متن کاملA new Replica Placement Algorithm in Data Grid
Replica placement is one of the important factors to improve performance in data grid systems. A good replica placement algorithm can result in good performance gains. It should be mentioned that, these algorithms or strategies are dependent on architecture of the data grid. By considering different kinds of architecture in data grid systems, a true representation of a grid is a general graph. ...
متن کاملOptimal Replica Placement in Data Grid Environments with Locality Assurance
Data replication is typically used to improve access performance and data availability in Data Grid systems. To date, research on data replication in Grid systems has focused on infrastructures for replication and mechanisms for creating/deleting replicas. The important problem of choosing suitable locations to place replicas in Data Grids has not been well studied. In this paper, we address th...
متن کاملP2P Based Decentralized Dynamic Replica Placement Strategy in Grid Environment
A big challenge to the grid computing is the communication on the network. The proper placement for replicas on multiple nodes in P2P or grid environment is an effective way to decrease network cost and improve communication efficiency. The unstable peers, networks, and fluctuant user access mode in the distributed environment make replica placement optimization difficult. We construct a networ...
