1. INTRODUCTION
The objectives of FTP are:
- To promote sharing of files (computer programs and/or data)
- To encourage indirect or implicit (via programs) use of remote computers
- To shield a user from variations in file storage systems among hosts
- To transfer data reliably and efficiently
FTP, though usable directly by a user at a terminal, is designed mainly for use by programs.
The attempt in this specification is to satisfy the diverse needs of users of maxi-hosts, mini-hosts, personal workstations, and TACs, with a simple, and easily implemented protocol design.
This paper assumes knowledge of the Transmission Control Protocol (TCP) [2] and the Telnet Protocol [3]. These documents are contained in the ARPA-Internet protocol handbook [1].
