Real-time Transport Protocol
Real-time Transport Protocol (RTP) is a network protocol designed for delivering audio and video over IP networks in real-time. It provides end-to-end delivery services for data with real-time characteristics, such as interactive audio and video, including payload type identification, sequence numbering, timestamping, and delivery monitoring. RTP is typically used in conjunction with the RTP Control Protocol (RTCP) to monitor transmission statistics and quality of service.
Developers should learn RTP when building applications that require real-time multimedia streaming, such as video conferencing (e.g., Zoom, Skype), live broadcasting, VoIP (Voice over IP), or online gaming. It is essential for ensuring timely delivery of time-sensitive data, minimizing latency, and synchronizing audio and video streams, making it a foundational technology for modern communication tools and media services.
