Overview

For an introduction to GRID data access please see Tutorial: Accessing Storage Elements. For help in selecting the best access protocols see The MINOS UK Data Model Currently MINOS do not use FTS or RFT.

Transfer protocols such as GridFTP have 2 weaknesses:-

They require the client to remain connected until the transfer completes.
They take no account of any global context so could result in server or client overloading or in copy duplication.

To addresses these weaknesses gLite has developed the File Transfer Service (FTS) and Globus offers Reliable File Transfer (RFT). Both of these middleware components offer clients a web service interface to which they can submit a request to copy a file from one grid storage element to another. Clients can then return to the web service to query the status of their requested transfer, while the services can schedule, load balance and retry failures between the received requests. Some implementations support file cataloging.
