Internet Engineering Task Force
The Internet Engineering Task Force (IETF) is a standards organization for the 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, an international non-profit organization. Organization The IETF is organized into a large number of working groups and birds of a feather informal discussion groups, each dealing with a specific topic. The IETF operates in a bottom-up task creation mode, largely driven by these working groups. Each working group has an appointed chairperson (or sometimes several co-chairs); a charter that describes its focus; and what it is expected to produce, and when. It is open to all who want to particip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Working Group
A working group, or working party, is a group of experts working together to achieve specified goals. The groups are domain-specific and focus on discussion or activity around a specific subject area. The term can sometimes refer to an interdisciplinary collaboration of researchers working on new activities that would be difficult to sustain under traditional funding mechanisms (e.g., federal agencies). The lifespan of a working group can last anywhere between a few months and several years. Such groups have the tendency to develop a ''quasi-permanent existence'' when the assigned task is accomplished; hence the need to disband (or phase out) the working group when it has achieved its goal(s). A working group's performance is made up of the individual results of all its individual members. A team's performance is made up of both individual results and collective results. In large organisations, working groups are prevalent, and the focus is always on individual goals, performan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instant Messaging
Instant messaging (IM) technology is a type of online chat allowing real-time text transmission over the Internet or another computer network. Messages are typically transmitted between two or more parties, when each user inputs text and triggers a transmission to the recipient(s), who are all connected on a common network. It differs from email in that conversations over instant messaging happen in real-time (hence "instant"). Most modern IM application (computing), applications (sometimes called "social messengers", "messaging apps" or "chat apps") use push technology and also add other features such as emojis (or graphical smileys), file transfer, chatbots, voice over IP, or Videotelephony, video chat capabilities. Instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a "buddy list" or "friend list"), and can be standalone applications or integrated into e.g. a wider social media platform, or a website ...

Presence Information
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 (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 willingness to communicate. The most common use of presence today is to di ...

Notification System
In information technology, a notification system is a combination of software and hardware that provides a means of delivering a message to a set of recipients. It commonly shows activity related to an account. Such systems constitute an important aspect of modern Web applications. For example, a notification system can send an e-mail announcing when a computer network will be down for a scheduled maintenance. The complexity of the notification system may vary. Complicated notification systems are used by businesses to reach critical employees. Emergency notification systems may take advantage of modern information technologies. Governments use them to inform people of upcoming danger. In mobile phones and smartphones, dedicated hardware such as a notification LED is sometimes included to deliver messages or notify users.

RFC 3339
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data. It is maintained by the Geneva-based International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019, and an amendment in 2022. The standard provides a well-defined, unambiguous method of representing calendar dates and times in worldwide communications, especially to avoid misinterpreting numeric dates and times when such data is transferred between countries with different conventions for writing numeric dates and times. ISO 8601 applies to these representations and formats: ''dates,'' in the Gregorian calendar (including the proleptic Gregorian calendar); ''times,'' based on the 24-hour timekeeping system, with optional UTC offset; ''time intervals''; and combinations thereof.ISO 8601:2004 section 1 Scope The standard does not assign specific meaning to any element of the dates/times re ...

Presence And Instant Messaging
Presence and Instant Messaging (PRIM) was an early proposal to the IETF of a standard protocol for instant messaging. The abstract model was first published as an IETF Request for Comments, RFC 2778 "A Model for Presence and Instant Messaging" in February 2000, which was authored by Mark Day of SightPath (formerly of Lotus Software where helped develop IBM Lotus Sametime, now Chief Scientist at Riverbed Technology), Jonathan Rosenberg of dynamicsoft (now the Chief Technology Officer and Vice President of Collaboration at Cisco Systems) and Hiroyasu Sugano of Fujitsu Laboratories LtdLtd. No work has been done on it since 2001. Currently, SIP and its derivative SIMPLE (both of which Jonathan Rosenberg also co-authored or invented), and XMPP are being considered for use as instant messaging protocols.

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 Hardphones. ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensible Messaging And Presence Protocol
Extensible Messaging and Presence Protocol (XMPP, originally named Jabber) is an Open standard, open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. Based on XML (Extensible Markup Language), it enables the near-real-time exchange of structured data between two or more network entities. Designed to be Extensibility, extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for Voice over IP, VoIP, video, file transfer, Game, gaming and other uses. Unlike most commercial instant messaging protocols, XMPP is defined in an open standard in the application layer. The architecture of the XMPP network is similar to email; anyone can run their own XMPP server and there is no central master server. This Federation (information technology), federated open system (computing), open system approach allows users to interoperate with ...

Instant Messaging Protocols
In physics and the philosophy of science, instant refers to an infinitesimal interval in time, whose passage is instantaneous. In ordinary speech, an instant has been defined as "a point or very short space of time," a notion deriving from its etymological source, the Latin verb ''instare'', from ''in-'' + ''stare'' ('to stand'), meaning 'to stand upon or near.' The continuous nature of time and its infinite divisibility was addressed by Aristotle in his ''Physics (Aristotle), Physics'', where he wrote on Zeno's paradoxes. The philosopher and mathematician Bertrand Russell was still seeking to define the exact nature of an instant thousands of years later. , the smallest time interval certify in regulated measurements is on the order of 397 zeptoseconds (397 × 10−21 seconds).
