Many companies consider instant messaging to be a distraction, but IM can be an effective communication tool if used properly. OpenFire is an open source enterprise IM server that has lots of features to streamline communication within an enterprise. The server is written in Java and uses Jabber, which is one of the most popular open protocols for real-time communication. In addition to being cross-platform, OpenFire is easy to set up and administer.
While the basic version of the OpenFire server is available free of cost, an enterprise version, which costs $15 per user per year, adds features suitable for a large multi-office corporation.
According to Jabber's Web site, OpenFire implements more features of the protocol than any other IM server. The server complements its pedigree by being easy to setup and administer. OpenFire will suit a wide range of enterprises, from home office setups to large multi-site enterprises, since it is dual-licensed under the GPL along with a commercial extension.
