Presence Information
In computer network, computer and telecommunications networks, presence information is a status indicator that conveys ability and willingness of a potential communication partner—for example a user (computing), user—to communication, communicate. A user's client (computing), client provides presence information (presence state) via a network connection to a presence service, which is stored in what constitutes his personal availability record (called a presentity) and can be made available for distribution to other users (called ''watchers'') to convey their 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. Presence state A user client may publish a presence state to indicate its current communication status. This published state informs others that wish to contact the user of his availability and wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Computer Network
A computer network is a collection of communicating computers and other devices, such as printers and smart phones. In order to communicate, the computers and devices must be connected by wired media like copper cables, optical fibers, or by wireless communication. The devices may be connected in a variety of network topologies. In order to communicate over the network, computers use agreed-on rules, called communication protocols, over whatever medium is used. The computer network can include personal computers, Server (computing), servers, networking hardware, or other specialized or general-purpose Host (network), hosts. They are identified by network addresses and may have hostnames. Hostnames serve as memorable labels for the nodes and are rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the tr ...

SIMPLE (instant Messaging Protocol)
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. Purpose SIMPLE applies SIP to the problems of: * registering for presence information and receiving notifications when such events occur, for example when a user logs in or comes back from lunch; * sending short messages, analogous to SMS or two-way paging; * managing a session of real-time messages between two or more participants. Implementations of the SIMPLE based protocols can be found in SIP Softphones and also in SIP Hardphon ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Comparison Of VoIP Software
This is a comparison of voice over IP (VoIP) software that examines applications and systems used for conducting voice and multimedia communications across Internet Protocol (IP) networks. VoIP technology has transformed telecommunications by offering alternatives to traditional telephony systems while providing enhanced features and cost savings. For residential users, VoIP services typically provide significant cost advantages compared to traditional public switched telephone network (PSTN) services. These systems eliminate geographic restrictions on phone numbers, enabling users to maintain local numbers in any area code regardless of their physical location. For example, a user can operate a New York phone number while residing in Tokyo, facilitating global mobility and reducing international communication costs. In enterprise environments, VoIP technology enables the consolidation of voice and data networks into a unified IP infrastructure. This consolidation eliminates the n ...

Comparison Of Cross-platform Instant Messaging Clients
The landscape for instant messaging involves cross-platform instant messaging clients that can handle one or multiple protocols. Clients that use the same protocol can typically federate and talk to one another. The following table compares general and technical information for cross-platform instant messaging clients in active development, each of which have their own article that provide further information. __TOC__ General Operating system support Connectivity Privacy Some messaging services that are not designed for privacy require a unique phone number for sign-up, as a form of identity verification and to prevent users from creating multiple accounts. Some messaging services that do not solely focus on a mobile-first experience, or enforce SMS authentication, may allow email addresses to be used for sign-up instead. Some messaging services offer greater flexibility and privacy, by allowing users to create more than one account to compartmentalize personal ...

IETF
The Internet Engineering Task Force (IETF) is a standards organization for the Internet standard, Internet and is responsible for the technical standards that make up the Internet protocol suite (TCP/IP). It has no formal membership roster or requirements and all its participants are volunteers. Their work is usually funded by employers or other sponsors. The IETF was initially supported by the federal government of the United States but since 1993 has operated under the auspices of the Internet Society, a non-profit organization with local chapters around the world. Organization There is no membership in the IETF. Anyone can participate by signing up to a working group mailing list, or registering for an IETF meeting. The IETF operates in a bottom-up task creation mode, largely driven by working groups. Each working group normally has appointed two co-chairs (occasionally three); a charter that describes its focus; and what it is expected to produce, and when. It is open ...

Facebook Messenger
Messenger, formerly known as Facebook Messenger, is an American proprietary instant messaging service developed by Meta Platforms. Originally developed as Facebook Chat in 2008, the client application of Messenger is currently available on iOS and Android mobile platforms, Windows and macOS desktop platforms, through the Messenger.com web application, and on the standalone Facebook Portal hardware. Messenger is used to send messages and exchange photos, videos, stickers, audio, and files, and also react to other users' messages and interact with bots. The service also supports voice and video calling. The standalone apps support using multiple accounts, conversations with end-to-end encryption, and playing games. With a monthly userbase of over 1 billion people it is among the largest social media platforms. History Following tests of a new instant messaging platform on Facebook in March 2008, the feature, then-titled "Facebook Chat", was gradually released to ...

XMPP Standards Foundation
XMPP Standards Foundation (XSF) is the foundation in charge of the standardization of the protocol extensions of Extensible Messaging and Presence Protocol, XMPP, the open standard of instant messaging and presence of the Internet Engineering Task Force, IETF. History The XSF was originally called the Jabber Software Foundation (JSF). The Jabber Software Foundation was originally established to provide an independent, non-profit, legal entity to support the development community around Jabber technologies (and later XMPP). Originally its main focus was on developing JOSL, the Jabber Open Source License (since deprecated), and an open standards process for documenting the protocols used in the Jabber/XMPP developer community. Its founders included Michael Bauer and Peter Saint-Andre. Process Members of the XSF vote on acceptance of new members, a technical Council, and a Board of Directors. However, membership is not required to publish, view, or comment on the standards tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
