  • adopts ejabberd and receives support from ProcessOne

    Posted by ProcessOne on March 06, 2006

    Paris, March 6, 2006 - chooses ejabberd instant messaging server, and gets support from ProcessOne, specialist of high-performance messaging solutions.

    What is ?

    Jabber is an instant messaging standard, defined by the Jabber Software Foundation (JSF) and standardized as eXtensible Messaging and Presence Protocol (XMPP) by the Internet Engineering Task Force (IETF). is both the reference website regarding Jabber, its extensions and its implementation and one of the most visible Jabber-based public instant messaging server. is probably the most famous Jabber server as it was historically the first in operation.

    Powered by ejabberd

    In February 2006, has upgraded to ejabberd. Switching to this software is an important decision for the admin team. The server currently has more than 185 000 registered users and regularly gathers over 10 000 simultaneous users. It also has nearly 2 000 connections to other jabber servers.

    For ejabberd and ProcessOne, this decision is a recognition of ejabberd's scalability, robustness and broad feature sets. As a result of this migration, the ProcessOne and teams will collaborate to improve the ejabberd software.

    This fact will boost ejabberd's development speed and will accelerate adoption for large scale Jabber deployments.

    About Jabber, XMPP, and the Jabber Software Foundation

    The Jabber Software Foundation (JSF) is a non-profit organization that builds open application protocols on top of the IETF's Extensible Messaging and Presence Protocol (XMPP). Widely considered the lingua franca of instant messaging, XMPP is an Internet standard for presence, real-time messaging, and streaming XML that grew out of the popular Jabber open-source technologies first released in 1999. With approval of XMPP by the IETF in 2004, the JSF continues to develop XMPP extensions that meet the needs of its many stakeholders: open-source and commercial developers (including Apple, HP, Oracle, and Sun), organizations large and small (including the U.S. defense establishment and most Wall Street investment banks), Internet and mobile service providers (including Google and Orange), and over 20 million end users worldwide.

    Interview with Peter Saint-Andre, Executive Director of the Jabber Software Foundation

    When has the server been launched ?

    Originally in 1999 (I think August). The server was the first Jabber server on the Internet and has always been considered the most prominent Jabber server on the network (the "center of the federation"). That's one reason why we have more server-to-server connections than any other server.

    How many different implementations have been used to run ?

    The server has always used the jabberd 1.x (before that jabberd 0.x) codebase. Several years ago we deployed connection manager software from Jabber Inc. to manage the large number of client and server connections we receive at the server, but we still used the jabberd 1.x codebase for the core router.

    Why has the team decided to switch to ejabberd ?

    We needed to switch from our older setup, which had some fairly serious stability issues. There were three possible solutions:

    1. Run a commercial, proprietary server such as Jabber XCP. This was unacceptable for political reasons (i.e, the server should be running open-source).
    2. Sponsor someone to write a scalable connection manager for jabberd 1.x. We didn't really consider this.
    3. Use an open-source server that could meet our scalability needs. From our knowledge of existing large deployments (e.g., and as well as test results posted on the Internet, that meant ejabberd.

    The JSF is committed to using open-source software whenever possible, so switching to ejabberd was a natural move for us.

    What is expecting from the migration to ejabberd ?

    Improved stability, full XMPP compliance, support for a wider range of XMPP extensions (e.g., pubsub), and a more frequently maintained codebase.
