Fast And Secure Protocol

Fast and Secure Protocol (FASP) is an alternative to transmission control protocol
(TCP) for reliable, bulk data transport developed by Aspera Inc. It is currently being promoted by Amazon.com

services as a way to greatly accelerate the rate of bulk data transfer over the public Internet. In tests, FASP has been shown to achieve full available bandwidth utilization, which ranges from a few times to hundreds of times faster than standard TCP over networks with high round-trip time and packet loss, where TCP fails to achieve full bandwidth utilization. The speed up factor is the difference between the TCP performance given the round-trip time and packet loss conditions of the transfer path, and the available bandwidth of the transfer path. These speed increases are achieved in the FASP protocol through a reliability mechanism that is fully separated from the rate control; the reliability mechanism retransmits dropped data at the available bandwidth capacity, and achieves nearly 100% good put (no duplicate retransmission) independent of round-trip time and packet loss. The transmission rate is separately determined through continuous detection of the available (unused) bandwidth capacity or according to a configured target rate.
Transmission Control Protocol
The Transmission Control Protocol is one of the core protocols of the Internet Protocol Suite. TCP is one of the two original components of the suite, complementing the Internet Protocol , and therefore the entire suite is commonly referred to as TCP/IP...
