Explanation:

The Real-Time Transport Protocol (RTP) is an Internet protocol standard that specifies a way for
programs to manage the real-time transmission of multimedia data over either unicast or multicast
network services. RTP is commonly used in Internet telephony applications. RTP does not in itself
guarantee real-time delivery of multimedia data; it does, however, provide the wherewithal to
manage the data as it arrives to best effect. RTP combines its data transport with a control
protocol (RTCP), which makes it possible to monitor data delivery for large multicast networks.
When protocols are used in conjunction, RTP is originated and received on even port numbers
and the associated RTCP communication uses the next higher odd port number. Monitoring allows
the receiver to detect if there is any packet loss and to compensate
The Secure Real-time Transport Protocol (or SRTP) defines a profile of RTP (Real-time Transport
Protocol), intended to provide encryption, message authentication and integrity, and replay
protection to the RTP data in both unicast and multicast applications. Since RTP is closely related
to RTCP (Real Time Control Protocol) which can be used to control the RTP session, SRTP also
has a sister protocol, called Secure RTCP (or SRTCP); SRTCP provides the same security-related
features to RTCP, as the ones provided by SRTP to RTP. Utilization of SRTP or SRTCP is
optional to the utilization of RTP or RTCP; but even if SRTP/SRTCP are used, all provided
features (such as encryption and authentication) are optional and can be separately enabled or
disabled. The only exception is the message authentication feature which is indispensably
required when using SRTCP.
On slow links, it may be advantageous to compress the IP/UDP/RTP headers using Compressed
RTP (cRTP). If you use cRTP then the 40 bytes of overhead incurred by the IP/UDP/RTP headers
can typically be compressed down to 2 to 4 bytes (2 bytes when no UDP checksums are sent, and
4 bytes when checksums are sent). Enabling compression on both ends of a low-bandwidth serial
link can greatly reduce the network overhead if it carries a lot of RTP traffic. cRTP is supported on
serial lines using Frame Relay, HDLC, or PPP encapsulation. It is also supported over ISDN
interfaces. CRTP should not be used on links greater than 2 Mbps.
