µTP consists of two parts: a framing scheme, and a congestion control algorithm that is less aggressive than that of TCP.

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<ref>{{cite web

===µTP framing===

µTP stores data within UDP datagrams using its own framing scheme. The framing scheme has functionality roughly equivalent to that of TCP (with timestamps and SACK), but realized in a somewhat idiosyncratic manner.

The µTP framing scheme is believed by some to be far from optimal<ref>http://forum.bittorrent.org/viewtopic.php?id=131</ref>.
