The Real-time Transport Protocol (RTP) is a network protocol designed for delivering audio and video over the internet. It is commonly used in applications like video conferencing and streaming media, where timely delivery of data is crucial. RTP works by breaking down media streams into smaller packets, which can be sent over the network and reassembled at the destination. RTP is often used in conjunction with other protocols, such as the Real-time Control Protocol (RTCP), which monitors the quality of service and provides feedback on the media transmission. Together, these protocols help ensure a smooth and efficient experience for users engaging in real-time communication, such as those using VoIP or video calls.
