real-time audio and video domain UDP is the kingly
The Transport layer scheme for real-time audio and video interaction on the Internet has two types: TCP (e.g. RTMP) and UDP (e.g. RTP). The TCP protocol provides a relatively reliable guarantee for data transmission between two endpoints, which is achieved through a handshake mechanism. When the data is passed to the receiver, the receiver checks the correc
