Digital Fountain Taps Data Flow: Page 2 of 4

In a typical scenario, FTP would take nearly 10 hours to send a 2-gigabyte file across the Atlantic, even across a 10-Mbit/s network, the company claims. Furthermore, intermittent network interruptions can cause the FTP session to abort. Additional bandwidth would provide almost no benefit, as it does nothing to address the send/acknowledge problem. By contrast, with Transporter Fountain, company officials say, the same data can be reliably delivered in just half an hour.

So how does it work?

Basically, the Transport Fountain servers need only receive a fixed number of packets from a file -- any packets, in any order. Each packet in the file contains the digital DNA of the entire file. If a hundred-packet file is sent, any hundred packets received will recreate the file, using Digital Fountain’s proprietary algorithms.

Sounds clever, eh?

The servers will slot into a Network Attached Storage (NAS) setup supporting the current widely adopted methods of file sharing, including Network File System (NFS), Common Internet File System (CIFS) and its predecessor SMB, as well as FTP.
