RFC 3550 - RTP: A Transport Protocol for Real-Time.
RTP (1) (Rapid Transport Protocol) The protocol used in IBM's High Performance Routing (HPR) system. (2) (Realtime Transport Protocol) An IP protocol that supports real-time transmission of voice and video.It is widely used for IP telephony and audio and video streaming. An RTP packet rides on top of UDP, the non-reliable counterpart of TCP, and includes timestamping and synchronization.

The Secure Real-time Transport Protocol (SRTP) is a Real-time Transport Protocol (RTP) profile, intended to provide encryption, message authentication and integrity, and replay attack protection to the RTP data in both unicast and multicast applications. It was developed by a small team of Internet Protocol and cryptographic experts from Cisco and Ericsson.
The first twelve octets are present in every RTP packet, while the list of CSRC identifiers is present only when inserted by a mixer. version (V): 2 bits This field identifies the version of RTP. The version defined by this specification is two (2). padding (P): 1 bit If the padding bit is set, the packet contains one or more additional padding octets at the end which are not part of the.
The User Datagram Protocol offers only a minimal transport service -- non-guaranteed datagram delivery -- and gives applications direct access to the datagram service of the IP layer. UDP is used by applications that do not require the level of service of TCP or that wish to use communications services (e.g., multicast or broadcast delivery) not available from TCP. UDP is almost a null.
UDP Bandwidth Control - is used to throttle the amount of bandwidth available for UDP traffic,. there are some predefined service types but it's possible to specify ones such as RTP that can't be predefined so would need to be configured manually in the (Service Type) section by clicking Edit as shown in the Setup Examples below. Setup Examples Prioritise VoIP Automatically (3.6.3 and later.
RTP relies on the underlying protocol(s) to provide demultiplexing of RTP data and RTCP control streams. For UDP and similar protocols, RTP uses an even port number and the corresponding RTCP stream uses the next higher (odd) port number. If an application is supplied with an odd number for use as the RTP port, it should replace this number.
