Distributed data transport service implement strategy in optical grid

A distributed data transport service implementing strategy is proposed to support grid network service with dynamic optical resource provisioning. The distributed data transport provides grid user with dynamic lightpaths. The test bed circling the resource managing and scheduling mechanism is built on the base of Globus Tookit 4. Optical grid middleware is developed to achieve grid network service, combining GridFTP and GMPLS network control, supporting network resource discovering, management and reservation. Also, the big-bulk data transport application spreads on the test bed with parallel lightpaths with the distributed and parallel transporting for the different data slices.
