The Real-time Transport Protocol (RTP) is a network protocol that operates on the Transport Layer of the OSI model. It is used to deliver audio and video over IPv4 and IPv6 networks. It is one of the primary components of VoIP as it carries the actual voice packets between VoIP endpoints.

It is also used in communication and entertainment systems that involve streaming media as well as video teleconference applications, television services, and web-based push-to-talk features.

RTP runs over UDP and is used in conjunction with RTP Control Protocol (RTCP) as well as with Session Initiation Protocol (SIP) which is a signaling protocol for voice and video communications.

Real-time Transport Protocol is not to be confused with Reliable Transport Protocol which uses the same acronym of RTP.
