File Transfer Protocol (FTP) is one of the oldest and simplest methods to transfer data from one host device to another over a private TCP-based network or the Internet. Even though it was developed during the pre-Cambrian era, FTP remains popular for bulk file transfers of video, images, or raw data. Given that FTP relies on TCP to control data flow across the connection, it suffers from the same challenges associated with any TCP link. (See TCP Optimization.)

FTP performance can slow considerably when data traverses fiber-based WAN’s and even more dramatically when moving over extreme links such as cellular or satellite due to high latency and limited network bandwidth.

FTP traffic typically contains compressible and repetitive elements. Acceleration Systems’ advanced compression and inline deduplication technologies dramatically reduce the total number of packets in repetitive, compressible data. Thus, our block level caching and compression technologies significantly reduce the volume of data moved in an FTP transfer.  (See Block Level Deduplication and Data Cache.) In addition, our TCP Optimization processes optimize performance of the link so FTP transfers run faster and more efficiently – regardless of distances or transmission media involved.
