RTP (Real-time Transport Protocol) and SRTP (Secure RTP)
The Real-time Transport Protocol (RTP) is a network protocol which described how to transmit various media (audio, video) from one endpoint to another in a real-time fashion. RTP is suitable for video-streaming application, telephony over IP like Skype and conference technologies.
The secure version of RTP, SRTP, is used by WebRTC, and uses encryption and authentication to minimize the risk of denial-of-service attacks and security breaches.
RTP is rarely used alone; instead, it is used in conjunction with other protocols like RTSP and SDP.
