XMPP – Extensible Messaging & Presence Protocol

XMPP instant messaging protocol that uses an open systems approach of development and application. It means that anyone who wants can  implement an XMPP service and that will give him the possibility to his app to interoperate with other implementations by other peoples apps.

Check out some other Layer 7 protocols:

There is no doubt about that real-time communication is the need of current time. To accomplish this assignment, different steps have been taken in the past but the struggle is still continued in order to introduce some excellent ways in this regard. Anyhow, XMPP (Extensible Messaging & Presence Protocol) is an open technology that is introduced for synchronized communication. This tool works in collaboration with the XML (Extensible Markup Language). That base-format is essential to exchange the online information because the process of sending XML small bits using XMPP between different entities in a synchronized way is possible with it.

Today, lots of applications are using XMPP for the right results. But this protocol services are defined by the IETF (Internet Engineering Task Force) specification as well as by the supplementary extensional specifications which are previously published by the XMPP Standards Foundation.

Open standard extensible messaging and presence protocol has come into existence for the messages oriented middleware for the purposes of communication. In fact, this protocol was at first developed with the name of “Jabber” (by the open-source Jabber community) in the year of 1999. The purpose of its creation was real time direct messaging and contact list maintenance etc. Though, XMPP messaging protocols are using the open development approach. But XMPP WG has been introduced RFC 3920 to RFC3923 (total four specifications) after getting these intended standards approval from a body internet engineering steering group (IESG).

XMPP standards foundation is claimed in the year 2003 and now this protocol based software is being used extensively over the Internet, worldwide.

Potential Features

XMPP network structural design is similar as of email. But because of decentralization (no middle master server) feature, any person can run their personal XMPP. Well! XMPP based networks are consisted of a client server environment. According to which a client can’t talk straightforwardly with another client. But decentralization of its design will not allow central authoritative server. So lots of users, running at jabber.org,will run their personal XMPP server over their personal domain. Likewise, no authority is required to put into practice XMPP specifications support.

Due to its open standards feature, their improvement isn’t limited to a sole vendor. To encourage security through channel encryption, digital certificates are offered by intermediate authority too. Flexibility is incorporated for custom functionality. XMPP applications offered group-chatting, file sharing, network management, gaming, remotely system’s control plus monitoring, cloud computing, and VoIP activities etc.

XMPP is required interoperability maintenance. And familiar extensions are manageable through “XMPP Software Foundation”. One more excellent trait of the XMPP system is the “gateways” or “transports”. That will permit the clients to get access to networks with the help of some other protocols such as instant and direct messaging protocols. But protocols like SMS and email are excluded in this regard. XMPP provides server level access by means of communicating through special gateways services. But these gateway services are running on the top of a distant computer system. A user, after the registration process with any one of available gateways can communicate with other network users. But XMPP is still not programmed as the “Efficient XML Interchange”. But Cisco Unified Presence is supporting on ad-hoc base as well as continual chat-rooms designed for XMPP-based users.
