RTP stands for Real-time Transport Protocol.
RTP is defined in IETF RFC 3550, with many additional RFCs referring to it and adding more functionality to it.
RTP is designed for sending and receiving media. To that end, it is implemented on top of UDP.
RTP’s packet header is 12 bytes (or more) at length.
RTP is NOT used by WebRTC. SRTP is used instead.
