Abstract
Apparatus and method to improve the speed of electronic file transfer between remote computers by parallel processing. The most common transfer protocol is the File Transfer Protocol (FTP) Though the Internet is the most popular means by which users electronically transport data, the Internet's Transport Control Protocol/Internet Protocol ('TCP/IP') model, upon which FTP operates, does not adequately support the transfer of large data sets over long distances. Typical transfers between distant sites linked via the Internet have throughputs of about 20 Kilobytes per second ('Kb/sec') or less, and they are prone to dropping packets or losing connections. Making FTP parallel makes transfers up to five times faster, that is, it offers transfer rates of up to 100 Kb/sec. FTP is operated in parallel by segmenting a file into discrete packets, simultaneously transmitting these packets to the receiving computer, and reassembling the packets into the original file. A log file that is independent of the packets and separately transmitted can aid reassembly.
