A lightpath provisioning scheme on demand for intensive data transfer in optical grid network

Optical grid provides scheduled optical network resource to grid application. For supporting intensive data in optical grid, LPoD service architecture is presented to implement multiple light paths scheduling on demand under the driven of applications. In the proposed architecture, we introduce load division for intensive data or huge size file to cut bulk data into fractions, which will be transferred by different light paths only if the original sending node owns multiple communication interfaces or using multi-wavelength paths. About the type of the applications that runs on optical grid with LPoD on load division, we illustrate the parallel and distributed computing, and compare the total expensing time under different processing ability and transmitting distances. The result shows that for remote collaborating job in optical grid, LPoD as communication resource providing method can satisfy grid demand. When there are many available nodes, selecting the nodes with nearer distance and strong processing will obtain good transmitting quality from executing time.
