Abstract
The data grid provides a scalable infrastructure for storage resources and distributed data management. It also supports a variety of scientific applications that require access to large amounts of data with a variety of QoS requirements.
Replication is the process of storing data in different locations to reduce access latency, improve data locality, and increase robustness, scalability and performance. It is the core mechanism of the data grid in that it enables scalable and efficient sharing of large volumes of data.
This paper focuses on faster and more reliable third-party transfer in the data grid with extending existing service, Reliable File Transfer Service. For faster transfer, we inspected, developed, and tested various transfer approaches, such as uniform, greedy, and probe-based, using replicas.
For more reliable transfer, we introduce the recursive assignment mechanism, which provides sophisticated fault tolerant transfer by re-assigning a failed sub-transfer.
The result of this work is a faster and more reliable file transfer service for the data grid, Replica Aware Reliable File Transfer Service.
