Real-Time Transport Protocol

(protocol)
(RTP) An Internet protocol for transmitting real-time data such as audio and video. RTP itself does not guarantee real-time delivery of data, but it does provide mechanisms for the sending and receiving applications to support streaming data. Typically, RTP runs on top of the UDP protocol, although the specification is general enough to support other transport protocols.

RTP has received wide industry support. Netscape intends to base its LiveMedia technology on RTP, and Microsoft claims that its NetMeeting product supports RTP.

These combined solutions enable organizations to deploy fully encrypted, validated and authenticated subscriber connections using the IETF standards, Transport Layer Security (TLS) for signaling information and its counterpart the Secure Real-time Transport Protocol (SRTP) for voice and video traffic.
Vendor equipment was placed in a common test bed and tests were completed using three standard interfaces, the Media Gateway Control Protocol (MGCP), the Real-time Transport Protocol (RTP), and the Session Initiation Protocol (SIP).
With the completion of the MPO project, Intelliverse is able to release calls back to the carrier allowing the Real-Time Transport Protocol (RTP) stream to flow directly from the originating caller to the called party without being pinned up through Intelliverse's switches.
The purpose of the event is to test the compatibility and interoperability of Internet Protocol-based voice products from different hardware and software manufacturers using common protocol specifications, including Media Gateway Control Protocol (MGCP), Real-time Transport Protocol (RTP), and Session Initiation Protocol (SIP).
Both NCS Network Continuity (analog/post-codec loopback) and real-time transport protocol (RTP pre-codec/NCS Network) loopback connections are supported, allowing operators to test media delivery and MTA codec performance independently.
It also prioritizes information when real-time transmission is required, and automatically recognizes Real-time Transport Protocol (RTP) for voice and video.
PowerProbe(R) service level test probes running Minacom's Real-time Transport Protocol (RTP) Streamer test agent can now perform loopback tests to cable transponders and measure key service quality metrics including VoIP speech quality (MOS, R-factor), packet jitter, delay, loss and a wide variety of other measurements to validate digital-video, Internet/data, and VoIP media quality and transmission performance.
The MSP8520 SoC also supports cryptographic acceleration for security algorithms and protocols such as Internet Protocol Security (IPsec), Secure Socket Layer (SSL), Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (SRTP).
The security functionality in PMC-Sierra's MSP8520 processor is provided by SafeNet's SafeXcel IP Packet Engine--a highly integrated cryptographic accelerator for security algorithms and protocols such as Internet Protocol Security (IPsec), Secure Socket Layer (SSL), Transport Layer Security (TLS), and Secure Real-Time Transport Protocol (SRTP).
The VX SAM is the industry's first wire-speed, full-capacity solution using the secure real-time transport protocol (SRTP) and provides military-grade encryption utilizing Mocana's standards-based embedded IPsec/IKE and FIPS 140-2 certified cryptography libraries.
