Research on file transfer task scheduling method in grid environment

Base on the research of GridFTP and P2P technology, this article seeks to put forward a high-performance, reliable file transfer task scheduling model and method in Grid environment, which characterized by support for basic security mechanisms, P2SP transmission, third-party control of transmission and ability to adapt to the dynamic, heterogeneous, distributed resources. Firstly, we set forth the current status and key technologies of grid-based task scheduling; then, with the description, we provide a task scheduling model and algorithm, which is achieved by P2SP technology and targeted file transfer.
