The Internet Engineering Task Force (IETF) is an open standards organization, which develops and promotes voluntary Internet standards, in particular the standards that comprise the Internet protocol suite (TCP/IP). It has no formal membership or membership requirements. All participants and managers are volunteers, though their work is usually funded by their employers or sponsors.
The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web.
The Internet Architecture Board (IAB) is "a committee of the Internet Engineering Task Force (IETF) and an advisory body of the Internet Society (ISOC). Its responsibilities include architectural oversight of IETF activities, Internet Standards Process oversight and appeal, and the appointment of the Request for Comments (RFC) Editor. The IAB is also responsible for the management of the IETF protocol parameter registries."
SIMPLE, the Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions, is an instant messaging (IM) and presence protocol suite based on Session Initiation Protocol (SIP) managed by the Internet Engineering Task Force. Contrary to the vast majority of IM and presence protocols used by software deployed today, SIMPLE is an open standard like XMPP.
An open standard is a standard that is publicly available and has various rights to use associated with it, and may also have various properties of how it was designed. There is no single definition and interpretations vary with usage.
In computer and telecommunications networks, presence information is a status indicator that conveys ability and willingness of a potential communication partner—for example a user—to communicate. A user's client provides presence information via a network connection to a presence service, which is stored in what constitutes his personal availability record and can be made available for distribution to other users to convey his availability for communication. Presence information has wide application in many communication services and is one of the innovations driving the popularity of instant messaging or recent implementations of voice over IP clients.
The Open Mobile Alliance (OMA) is a standards body which develops open standards for the mobile phone industry. It is not a formal government-sponsored standards organization like the ITU, but a forum for industry stakeholders to agree on common specifications for products and services.
The Gateway Control Protocol is an implementation of the media gateway control protocol architecture for providing telecommunication services across a converged internetwork consisting of the traditional public switched telephone network (PSTN) and modern packet networks, such as the Internet. H.248 is the designation of the recommendations developed by the ITU Telecommunication Standardization Sector (ITU-T) and Megaco is a contraction of media gateway control protocol used by the earliest specifications by the Internet Engineering Task Force (IETF). The standard published in March 2013 by ITU-T is entitled H.248.1: Gateway control protocol: Version 3.
SIPfoundry is a not-for-profit organization, whose mission is to promote and advance open-source software projects based on the Session Initiation Protocol (SIP). The community aims to support users, developers, and distributors of SIP-based products.
sipXecs is an open-source enterprise communications system. It was initially developed as a proprietary voice over IP telephony server in 2003 by Pingtel Corporation in Boston, MA, and later extended with additional collaboration capabilities in the SIPfoundry project. Its core feature is a software implementation of the Session Initiation Protocol (SIP), which makes it an IP based communications system.
The OpenAjax Alliance is an industry group devoted to the set of technologies and Web programming techniques known as Ajax.
The International Multimedia Telecommunications Consortium (IMTC) is an organization consisting of several companies interested in real-time, rich-media communications. Rich media includes voice and one-way data and one-way video. Members of this community include Internet application developers and service providers, teleconferencing hardware and software suppliers and service providers, telecommunications service providers and equipment vendors, end users, educational institutions, government agencies and non-profit corporations. On July 28, 2014 IMTC and the Unified Communications Interoperability Forum (UCIF) merged into one consortium. The UCI Forum defined interoperability profiles and certification tests, implementation guidelines, and best practices for interoperability between UC products and existing applications.
XMPP Standards Foundation (XSF) is the foundation in charge of the standardization of the protocol extensions of XMPP, the open standard of instant messaging and presence of the IETF.
Peer-to-peer SIP (P2P-SIP) is an implementation of a distributed voice over Internet Protocol (VoIP) or instant messaging communications application using a peer-to-peer (P2P) architecture in which session control between communication end points is facilitated with the Session Initiation Protocol (SIP).
The IPSO Alliance was an organization promoting the Internet Protocol (IP) for what it calls "smart object" communications. The IPSO in IPSO Alliance is short for Internet Protocol for Smart Objects. The IPSO Alliance was a non-profit organization founded in 2008 with members from technology, communications and energy companies. The IPSO Alliance advocated for IP networked devices in energy, consumer, healthcare and industrial applications. On March 27, 2018 the IPSO Alliance merged with the Open Mobile Alliance (OMA) to form OMA SpecWorks.
CalConnect, the Calendaring and Scheduling Consortium, is a partnership among vendors, developers, and customers to advance calendaring and scheduling standards and implementations. The mission is to provide mechanisms to allow calendaring and scheduling methodologies to interoperate, and to promote broad understanding of these methodologies so that calendaring and scheduling tools and applications can enter the mainstream of computing. The Consortium develops recommendations for improvement and extension of relevant standards, develops requirements and use cases for calendaring and scheduling specifications, conducts interoperability testing for calendaring and scheduling implementations, and promotes calendaring and scheduling.
In computer networking, the Message Session Relay Protocol (MSRP) is a protocol for transmitting a series of related instant messages in the context of a communications session. An application instantiates the session with the Session Description Protocol (SDP) over Session Initiation Protocol (SIP) or other rendezvous methods.
The media gateway control protocol architecture is a methodology of providing telecommunication services using decomposed multimedia gateways for transmitting telephone calls between an Internet Protocol network and traditional analog facilities of the public switched telephone network (PSTN). The architecture was originally defined in RFC 2805 and has been used in several prominent voice over IP (VoIP) protocol implementations, such as the Media Gateway Control Protocol (MGCP) and Megaco (H.248), both successors to the obsolete Simple Gateway Control Protocol (SGCP).
The Session Initiation Protocol (SIP) is the signaling protocol selected by the 3rd Generation Partnership Project (3GPP) to create and control multimedia sessions with two or more participants in the IP Multimedia Subsystem (IMS), and therefore is a key element in the IMS framework.
