The '''Fast Adaptive and Secure Protocol''' ('''FASP''') is a [[Proprietary software|proprietary]] data transfer [[Communication protocol|protocol]]. FASP is a network-optimized network protocol developed by [[Aspera (company)|Aspera]], owned by [[IBM]]. The associated client/server software packages are also commonly called Aspera.<ref name="register">{{cite web|url=https://www.theregister.co.uk/2015/10/01/aspera/|title=Aspera high speed file transfer: Let the cloud protocol wars begin}}</ref><ref name="ena">{{cite web|url=https://www.ebi.ac.uk/ena/browse/read-download#downloading_files_aspera|title=European Nucleotide Archive: Downloading using Aspera}}</ref> The technology is [[patented]] under US Patent #20090063698, ''Method and system for aggregate bandwidth control''.<ref>{{cite web|url=https://www.google.com/patents/US20090063698|title=Method and system for aggregate bandwidth control}}</ref>

Similar to the [[Connectionless communication|connectionless]] [[User Datagram Protocol|UDP]] protocol, FASP does not expect any feedback on every [[Network packet|packet]] sent. 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]].<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>
