GridFTP Multilinking

GridFTP is the de facto standard in projects requiring secure, robust, high-speed bulk data transport. For example, the high energy physics community is basing its entire tiered data movement infrastructure for the Large Hadron Collider computing Grid on GridFTP; the Laser Interferometer Gravitational Wave Observatory routinely uses GridFTP to move 1 TB a day during production runs; and GridFTP is the recommended data transfer mechanism to maximize data transfer rates on the TeraGrid. GridFTP is well known for efficiently transferring data from one destination to another. In this paper, we present a new feature for GridFTP – multilinking – and show how it can be used to transfer a single file to many destinations efficiently.
