What is Google Talk


Google Talk is a software owner and instant messaging service, and voice over IP based on Jabber developed by Google released beta August 24, 2005. Google Talk is both the service and the proprietary customer to be connect to this service.

Windows 2000, 2003, XP, Vista the 2006 version of PDA Nokia 770 which runs under Linux on Blackberry

Its interface tries to distinguish itself by its simple and light, and not overloaded.

Open standard protocol


Unlike other instant messaging software, Google Talk uses the open standard protocol Jabber / XMPP, while encouraging them to use their own client to connect to the Google Talk service.

By using an open protocol, you can also connect to the instant messaging service Google Talk from a standard Jabber client. Voice over IP is not yet fully developed. The communication inter-Jabber server ("s2s" to "server to server") has been implemented in the Google Talk service January 17, 2006, Google Talk is open to all the network global public Jabber network (called " federated ").

Voice


VoIP uses the open protocol Jingle being standardized and free codecs (speex) and owners (GIPS).

Integration in Gmail


In 2005 for the U.S. version, Google Talk integration has benefited from its services in Gmail. It is now possible to use most of the functions of instant messaging from online email service from Google, which can among other things enable chat while viewing their emails or vice versa, but also be able to do this on almost any operating system and any browser (Firefox, Internet Explorer, Opera, Camino, etc.).. In addition, the default Gmail offers the ability to keep all the conversations made ​​using the integrated Google Talk service.

Technical


Google announced that the main goal of the Google Talk service is the interoperability . Google Talk uses Jabber (XMPP) to provide instant messaging extensible. Since January 2006, Google Talk enables communication from server to server, and users and Google Talk users can talk to other Jabber servers audiences world -wide.

December 15, 2005, Google released libjingle , a free library written in C + + implementing Jingle, a set of extensions to XMPP to support voice over IP (VoIP), and eventually the file transfer and video (link) among others (Jingle is a session initiation protocol multimedia).

Google Talk does figure not flow Jabber, but instead uses a non-documented and non-standard to authenticate to the service, by retrieving a token from a secure web server. Customers other than Google must secure their streams with TLS before sending the password, so they remain encrypted throughout the session. Google says that all messages (text and audio) will be encrypted in future versions (link) .

The configurable options are deliberately very limited. The official client offers uninstalling the software Gmail Notifier, which performs the same functions and adds new options.

Google Talk offers, as some IM clients, support for themes chat windows. For this, it uses the same theme originally created for Adium but also used by Kopete and Skype for Mac OS X . This system is based on the theme XHTML and CSS.
