Optimizing FTP File Transfers with BIG-IP WAN Optimization Module

FTP

File Transfer Protocol (FTP) is a standard network protocol used to exchange and manipulate files over a TCP/IP-based network, such as the Internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server applications. FTP can be used with user-based password authentication or with anonymous user access.

As with all large data transfers across the Internet, FTP is susceptible to interruption from poor quality connections. It is also a relatively slow protocol that can be open to man-in-the-middle attacks even if authentication is turned on.

As files grow larger and the distance between source and destination also grows, the need for acceleration of FTP transfers increases. A secure communications mechanism that allows for the transfer of files across the Internet is also necessary to maintain privacy and insure compliance with regulations such as SOX and HIPPA.

BIG-IP WOM uses TCP optimizations to speed TCP connections and reduce latency, Symmetric Adaptive Compression to reduce the amount of data sent over the remote connection, and iSessions to encrypt data as it passes across the Internet.

Solution

BIG-IP WOM enables customers to:

• Accelerate FTP transfers across the WAN
• Mitigate the effects of latency
• Optimize existing bandwidth when sending duplicated data, thus controlling costs and eliminating the need for costly bandwidth upgrades
• Guarantee bandwidth and prioritize FTP traffic

BIG-IP WOM does this by layering optimization techniques onto the F5 TMOS product platform.
