micro Transport Protocol or µTP is a protocol used by bittorrent computer applications to communicate across the internet.
It was devised to increase the speed at which packets of data are transmitted between users of peer-to-peer file sharing torrents, which allows individuals to share files such as music, video and software with groups of other users.
As it is difficult for some people to type the Greek letter mu, µTP is often written uTP.
Development
Based upon the User Datagram Protocol (UDP), µTP aims to decrease latency caused by applications using the protocol while maximizing bandwidth when latency is not excessive[1]. Information from the transport can be used to control the transfer rate of TCP connections to prevent disruption of the used Internet connection.[2]
uTP was first publicly introduced in the alpha builds of µTorrent 1.9, though partial support for the protocol was already implemented in the µTorrent 1.8.x Beta branches.[3][4]
Because it is still being implemented, uTP protocol features are typically hidden or made obscure in the client user interfaces of the BitTorrent clients that support it. There is no open source uTP protocol codebase at this time, making this feature's support with other BitTorrent clients much less uniform. It may take until late 2009 or early 2010 until this feature is readily accessible with a user friendly interface.
