RTP – Real-time Transport Protocol
RTP (Real-time Transport Protocol)
Application layer protocol RTP is accessible in the TCP/IP protocol suite. Assigned port for this protocol is 5004 and it belongs to the working groups “AVT” and “FEC Framework”. As a standardized packets format, Real-time Transport Protocol (RTP) is used to deliver the audio or video or both on the IP networks. IETF standards association working group of Audio and Video Transport was built up it, at first.
Features of RTP are included end to end communication and data streams transmission in real time manners. But transfer of data to more than one destination is done with the IP multicast support in case of RTP. Moreover, RTP as a primary audio/video transport standard within the IP networks is used along with payload format and connected profile. Today, communication and entertainment systems with streaming media (telephony) are being used it extensively. And some common examples of such systems are such as teleconference applications and television services.
