<protocol> (FSP) A protocol, similar to FTP, for copying files between computers. It's designed for anonymous archives, and has protection against server and network overloading. It doesn't use connections so it can survive interruptions in service.
Until 1993-08-12, FSP didn't stand for anything. Wen-King was responsible for the initials and Michael Grubb <firstname.lastname@example.org> for their eventual expansion. Other suggestions were "File Slurping Protocol", "Flaky Stream Protocol" and "FTP's Sexier Partner".
