Instant Messaging Protocols
Introduction
Instant messaging provides the instantaneous communication of a telephone call, while avoiding the
feelings of directness and confrontation of a tete-a-tete with the detachment of written
correspondence, making instant messaging a popular and flexible form of communication. It allows
two or more users to exchange text information in real time.
There are a number of IM protocols. The most widely used is the ICQ protocol. However we have
decided on the Jabber protocol because Jabber has several significant advantages over the ICQ
protocol.
The Jabber protocol is particularly popular in the corporate environment. It's hosted on distributed
servers which provides uninterruptible service, and it's an open source protocol, so it can be
adapted to work with many other protocols.
Jabber protocol
Jabber is a extensible Instant Messaging protocol and it has accumulated various features over time
such as Voice over IP and file transfer signaling. Unlike most instant messaging protocols, it is an
open standard, which makes it more reliable. Like e-mail, Jabber is an open system, meaning
anyone who has a domain name and a suitable Internet connection can run their own Jabber server
and talk to users on other servers. The standard server implementations and many Jabber clients
are also freeware or open source software.
Advantages of Jabber protocol
The architecture of the Jabber network is similar to email; anyone can run their own Jabber
server and there is no central master server.
No royalties are required to implement support of these specifications and their development
is not tied to a single vendor.
Jabber servers may be isolated from the public Jabber network (e.g. on a company intranet),
and robust security (via SASL and TLS) has been built into the core specifications.
ICQ support
The support of ICQ protocol is done through the use of a transport, small computer program that
sits on the server and translates and Jabber messages into other IM formats. In order to
communicate with ICQ and other IM users, you have to register the transport. This product will help
you setup your account and customize your account details.
