Abstract
To solve the problems that creating a number of copies in data grid systems can bring great overheads in data storage and network traffic and a variety of parallel download algorithms based on the GridFTP protocol can not eliminate the influence of multi-copy on the storage space and network traffic, the paper puts forward a storage model for data grid systems to guarantee data integrity, storage reliability and reduce storage space, and presents a parallel download scheduling algorithm based on the model and the GridFTP protocol. The experimental results show that the proposed algorithm can achieve a better effect in fast parallel transmitting, storage space saving and network traffic reducing.
