Media Transmission Protocols
In a VoIP network, the absolute articulation abstracts (conversations) are transported beyond the transmission
media application RTP and RTP Ascendancy Agreement (RTCP). RTP defines a standardized
packet architecture for carrying audio and video over the Internet. RTCP is a accompaniment protocol
to RTP as it provides for the commitment of ascendancy advice for alone RTP
streams. Compressed Real-time Transport Agreement (cRTP) and Secure Real-time
Transport Agreement (sRTP) were developed to enhance the acceptance of RTP.
Datagram protocols, such as UDP, accelerate a media beck as a alternation of baby packets. This
approach is simple and efficient. However, packets are accountable to be absent or besmirched in
transit. Depending on the agreement and the admeasurement of the loss, a applicant ability be able to
recover absent abstracts with absurdity alteration techniques, ability admit over the missing
data, or ability ache a abstracts dropout. RTP and the RTCP were accurately advised to
stream media over networks. They are both congenital on top of UDP.
