Q&A
Q. | Why are the primary Transport layer protocols ill-suited for streaming? |

Q. | What is the purpose of RTP’s two sister protocols, RTCP and RTSP? |
A. | While RTP provides the streaming, RTCP monitors and reports on quality of service. RTSP is used for control commands to start or stop the stream. |
