(1) (Rapid Transport Protocol) The protocol used in IBM's High Performance Routing (HPR) system.

(2) (Realtime Transport Protocol) An IP protocol that supports real-time transmission of voice and video. It is widely used for IP telephony and audio and video streaming. An RTP packet rides on top of UDP, the non-reliable counterpart of TCP, and includes timestamping and synchronization information in its header for proper reassembly at the receiving end. Secure RTP (SRTP) is a version of RTP that provides confidentiality and message authentication.

RTCP (Real Time Control Protocol)
RTCP is a companion protocol to RTP that is used to maintain QoS. RTP nodes analyze network conditions and periodically send each other RTCP packets that report on network congestion.

RTSP (Real Time Streaming Protocol)
RTSP is used to control an RTP session at the application layer. It enables functions such as pause, rewind and fast forward to be provided in the user's client software. See IP telephony, RSVP, session border controller and UDP.

RTP Packet
In a UDP/IP stack, the RTP header is created first and then the packet is moved down the stack to UDP and IP. This shows the RTP packet within an Ethernet frame ready for transmission over the network.

In Step 27, an RTCP Floor Release is sent to the PoC server when UE-B releases the Talk button, and then the PoC server responds with an RTCP Floor Idle to inform all group members that the media channel is available from Step 28 to Step 30.

VQattest generates RTP streams with voice payloads and incorporates RTCP SR, RR and XR reporting.
In the proposed system, we use the RTP (Real-time Transport Protocol) and the RTCP (Real-time Transport Control Protocol) protocols for the delivery of video data and for the feedback on network quality.
RTCP (Real-time Transport Control Protocol) is accompanying the RTP protocol to transmit the feedback from receiver to sender's RTP side.
