Protocol Stacks

The Agora Labs RTP/RTCP stack is an implementation of the IETF RFC1889/RFC3550 Internet standards. RTP defines a standardized packet format for delivering audio and video over the Internet or other packet based networks.

Applications typically run RTP on top of UDP to make use of its multiplexing and checksum services. RTP can be used in both multicast and unicast applications. It is frequently used in streaming media systems as well as videoconferencing systems (in conjunction with H.323 or SIP). It is the foundation for media transport for all VoIP and Video over IP applications.
