FastTCP Commercialized Into An FTP Appliance
prostoalex writes "FastTCP technology, developed by researchers at CalTech, is being commercialized. A company called FastSoft has introduced a hardware appliance that delivers 15x-20x faster FTP transmissions than those delivered via regular TCP. Says eWeek: 'The algorithm implemented in the Aria appliance senses congestion by continuously measuring the round-trip time for the TCP acknowledgment and then monitoring how that measurement changes from moment to moment.'"
TCP does not have anything at all to do with the Shannon Limit. The Shannon limit lets you know how fast it is possible to send the bits with a given error rate over a finite bandwidth channel in the presence of noise. It does not have anything to say about higher level protocols.
