In computer networking, the Reliable User Datagram Protocol (RUDP) is a transport layer protocol designed at Bell Labs for the Plan 9 operating system. It aims to provide a solution where UDP is too primitive because guaranteed-order packet delivery is desirable, but TCP adds too much complexity/overhead.

It extends UDP by adding the following additional features:

RUDP is not currently a formal standard, however it was described in an IETF [internet-draft] in 1999. It has not been proposed for standardization.
