GridFTP is a transport protocol designed by the Global Grid Forum for bulk data transport in a grid environment. (References: GFD.020, RFC 959, RFC 2228, RFC 2389.)

Within LCG gridftp servers tend to be based on the Globus GT2 gridftp server or on the COG java toolkit.

GridFTP is particularly nasty to get to work through firewalls, although the GT4 version offers improvements in this regard and might be used in LCG.
