Faster File transfer

Aria using FastTCP to speed up transfers

Aria, a new product from California-based startup FastSoft, speeds up the transfer of any large file over the Internet, without requiring hardware or software on the receiving end. According to Dan Henderson, FastSoft's vice president of product and market development, a 700-megabyte movie file that takes 50 minutes to download regionally via a cable-modem connection can be downloaded in 34 minutes if the sender uses Aria. Overseas transfers show a bigger difference, with the same 700-megabyte movie taking nearly eight hours to download from Asia via a cable modem, and about 45 minutes with Aria.

Caltech researchers designed FastTCP, the algorithm behind Aria, to improve on Reno(Normal TCP protocol). In academic trials, Henderson says, FastTCP has set data-transfer records, transferring data at a sustained rate of 101 gigabits per second. That's equivalent to transmitting the contents of the Library of Congress in 15 minutes.
