Perkins, "Guidelines for Extending the RTP Control Protocol (RtcP
)", RFC 5968, September 2010.
Real Time Control Protocol (RTCP
) attribute in Session Description Protocol (SDP).
Linphone implements part of RTCP
(real-time control protocol) so that the receiver would send an ACK back to the sender when it receives the voice packets.
The disadvantage with RTP is that it lacks a mechanism to report the status of the communication, so that it usually relies on the RTCP
During the media session, the MDCA module acquires the network context information from the RTCP
protocol statistic reports mainly indicating the jitter, packet loss and round-trip delay (message 1) and transmits to the CAS using HTTP POST (messages 2-3)
In addition, CDR (call data record) and RTCP
(Real-time Transport Control Protocol) based reports can deliver rich statistics for each completed call leg, again enabling call quality measurements to be compared against baselines, and threshold-based alerts issued accordingly.
In addition the SVS-8 supports unicast and multicast streams, as well as the RTP, RTCP
, RTSP, SAP, TCP and UDP protocols, among others.
These streams are synchronized on the terminal by RTCP
Combined with RTCP
(Real-time Control Protocol), RTSP (Real-time Streaming Protocol) and RSVP (Real-time Reservation Protocol) Realtime transport protocol though uses UDP connections.
Another issue is the approach that requires the use of real-time control protocol (RTCP
), which is associated with RTP media.
