is a high-speed file transfer solution (by Fortra, formerly Help/Systems) that uses UDP-based acceleration to move large files over long distances, high-latency, or high-packet-loss networks. IBM integrates FileCatalyst into several of its enterprise content management and storage offerings.

: Using IBM’s global footprint to push large software updates to edge locations at maximum speed.

Traditional file transfer protocols (like FTP or HTTP) rely on TCP/IP, which was not designed for the high-latency, high-bandwidth networks of today’s global enterprises. When moving terabytes of data across continents or into the cloud, packet loss and latency can severely throttle transfer speeds.
