µTP emerged from research at Internet2 on QoS and high-performance bulk transport, was adapted for use as a background transport protocol by Plicto, that was founded by Stanislav Shalunov[REF] and later it was acquired by BitTorrent, Inc. in 2006, and further developed within its new owner [REF].
The first free software client to implement µTP was KTorrent 4.0 [REF].
