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, such as in video conferencing, streaming media, and telephony. It provides end-to-end network transport functions suitable for applications transmitting real-time data, including payload type identification, sequence numbering, timestamping, and delivery monitoring. RTP is typically used in conjunction with the RTP Control Protocol (RTCP) to monitor data delivery and provide minimal control and identification functionality.
Developers should learn RTP when building applications that require real-time multimedia communication, such as VoIP systems, video conferencing tools, live streaming platforms, and online gaming with voice chat. It is essential for ensuring timely delivery of time-sensitive data with synchronization, making it critical for low-latency applications where delays degrade user experience. Understanding RTP helps in implementing efficient media streaming and handling network challenges like jitter and packet loss.
