BFCP is a protocol which allows control of a virtual conference floor in VoIP multimedia conferences. BFCP is specified in RFC 4582. A floor is a shared conference resource, which is available only to a single participant at a time. If the ability to present is considered such a resource, ...

Diameter is an extensible messaging protocol defined by RFC 3588, enabling Authentication, Authorization and Accounting within and across IP multimedia networks that rely on secure and reliable transports. The protocol evolved from the RADIUS protocol but is much more scalable and well defined, has fail-over capabilities, runs over secure TCP/SCTP ...

MSRP stands for Message Session Relay Protocol and is defined by IETF in RFC4975 and RFC 4976. MSRP is open text-based protocol which allows transmission of the media content of various size in the instant messaging scenarios via established session. MSRP can be used for text and file/image transfer in ...

RTCP stands for Real Time Transport Control Protocol and is used in conjuction with RTP. It is defined along with RTP in RFC 3550.The main purpose of RTCP is to gather and report statistical information about the media sent over RTP - information that can be used by the sender ...

Real Time Transport Protocol (RTP) is an IP protocol that supports real-time transmission of voice and video. It is widely used for IP telephony.RTP is defined in RFC 3550 which obsoletes an older version of this protocol in RFC 1889.RTCP is a companion protocol that is used to maintain QoS.RTP ...

RTSP stands for Real-Time Streaming Protocol.RTSP is an application-level protocol for controlling the delivery of real-time data, such as audio and video. The RTSP protocol is coupled with data transport protocols such as RTP; while real-time data is transported over RTP, the flow ofthe data is controlled by RTSP.As a ...

Stream Control Transmission Protocol (SCTP) is a transmission layer, such asTCP or UDP.SCTP is a connection-oriented protocol (such as TCP), that deals with datagrams (such as UDP) rather than byte streams (such as TCP).Unlike TCP, SCTP provides a number of functions thatare critical for telephony reliable signaling transport over a ...

SIMPLE stands for Session initiation protocol for Instant Messaging and Presence Leveraging Extensions. SIMPLE is defined by IETF and uses another IETF protocol, SIP as a core. SIMPLE is an open standard which allows development of interoperable Presence and Instant messaging applications. SIMPLE protocol functionality is based on the number ...

The Session Initiation Protocol (SIP) is a signaling protocol for initiating, managing and terminating voice and video sessions across packet networks. Borrowing from Internet protocols, such as HTTP and SMTP, SIP is text-encoded and highly extensible. SIP can be extended to accommodate features and services such as call control services, ...

The Extensible Messaging and Presence Protocol (XMPP) is an open standard for real-time communication. In a sense, XMPP is a way to route XML data between entities.XMPP is being standardized within the IETF. The core of the XMPP protocol is publised as RFC 3920.The core XMPP protocol offers the basic ...
