# utp [![GoDoc](https://godoc.org/github.com/anacrolix/utp?status.svg)](https://godoc.org/github.com/anacrolix/utp) [![CircleCI](https://circleci.com/gh/anacrolix/utp.svg?style=shield)](https://circleci.com/gh/anacrolix/utp) Package utp implements uTP, the micro transport protocol as used with Bittorrent. It opts for simplicity and reliability over strict adherence to the (poor) spec. ## Supported * Multiple uTP connections switched on a single PacketConn, including those initiated locally. * Raw access to the PacketConn for non-uTP purposes, like sharing the PacketConn with a DHT implementation. ## Implementation characteristics * There is no MTU path discovery. * A fixed 64 slot selective ack window is used in both sending and receiving. Patches welcomed.
