Built upon the [[Connectionless communication|connectionless]] [[User Datagram Protocol|UDP]] protocol, FASP does not expect any feedback on every [[Network packet|packet]] sent, and yet provides fully reliable data transfer over best effort IP networks. Only the packets marked as really lost must be requested again by the recipient. As a result, it does not suffer as much loss of throughput as [[Transmission Control Protocol|TCP]] does on networks with high [[Latency (engineering)|latency]] or high [[packet loss]] and avoids the overhead of naive "UDP data blaster" protocols.<ref>{{cite web|url=http://downloads.asperasoft.com/en/technology/shortcomings_of_TCP_2/the_shortcomings_of_TCP_file_transfer_2|title=Aspera - High-speed file transfer software -|website=downloads.asperasoft.com}}</ref><ref>{{cite web|url=https://gcn.com/Articles/2014/05/15/FOSE-Data-transfer-protocol.aspx|title=FASP transfer protocol speeds data transmission to the cloud}}</ref> The protocol innovates upon naive "data blaster" protocols through an optimal control-theoretic retransmission algorithm and implementation that achieves maximum goodput and avoids redundant retransmission of data. Its control model is designed to fill the available bandwidth of the end-to-end path over which the transfer occurs with only "good" and needed data.

Large organizations like [[IBM]],{{citation needed|date=January 2018}} the [[European Nucleotide Archive]],<ref name="ena" /> the US [[National Institutes of Health]] [[National Center for Biotechnology Information]]<ref>{{cite web|url=https://www.ncbi.nlm.nih.gov/projects/faspftp/1000genomes/|title=NCBI 1000 Genomes: Aspera Download}}</ref> and others<ref>{{cite web|url=http://asperasoft.com/partners/joint-partner-solutions/|title=Aspera Joint Partner Solutions|date=20 January 2018|website=asperasoft.com}}</ref> use the protocol in different areas. [[Amazon (company)|Amazon]] also wants to use the protocol for uploading to data centers.<ref>{{cite web|url=https://www.heise.de/newsticker/meldung/Amazon-nutzt-schnelleres-uebertragungsprotokoll-fuer-Web-Services-788844.html|title=Amazon nutzt schnelleres Übertragungsprotokoll für Web Services|last=Schwan|first=Ben|website=heise online}}</ref> The technology was recognized with many awards including an Engineering Emmy from the Academy of Film and Television. Finally, while there is no published crossover, the protocol appears to be an inspiration for Google's BBR high speed TCP as BBR uses many concepts described and implemented in the FASP specification.
