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.'"
FastTCP sounds like a fancy name for TCP Vegas (which has been around for quite some time). Window scaling and Vegas should buy you pretty much everything that FastTCP seems to be offering... Sounds like marketspeak to me.
No. TCP is end to end, the nodes in between could not care less (except for dubious filtering purposes) what layer 4 protocol is piggybacking upon IP proper.
