Jabber XCP 5.2 Now Available.

Improved SIP/SIMPLE Support, Scalability, and Security Enhancements Top List of Jabber XCP Upgrades

DENVER -- Jabber, Inc. today announced the general availability of the 5.2 release of the Jabber Extensible Communications Platform[TM] (Jabber XCP[TM]). The highly programmable, scalable, and secure presence platform enhanced its industry leadership position with the addition of:

* A Session Initiation Protocol (SIP)/SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE) Gateway delivered on a new code base providing for transparent federation with SIP/SIMPLE-based messaging systems such as IBM Lotus Sametime, Microsoft Live Communications Server, and the AOL Instant Messenger service. A cornerstone of the company's multi-protocol approach to real-time messaging, the new SIP/SIMPLE implementation is now available on the Microsoft Windows Server platform in addition to Solaris and Linux.

* Sun Solaris 10 support, the platform on which recent loads tests (http://www.jabber.com/index.cgi?CONTENT_ID=1080) confirmed Jabber XCP's ability to scale past a million concurrent users. Jabber XCP is also available for the Solaris 9, Red Hat Enterprise Linux 3.0 and 4.0, Microsoft Windows Server 2000 and 2003 platforms.

* InfoBroker (http://www.jabber.com/index.cgi?CONTENT_ID=622) enhancements that optimize the efficiency and scalability of Jabber XCP's publish-and-subscribe module.

* Increased security integrity of Jabber XCP through obscured password storage in encrypted files.

* Stanza optimization, through the implementation of XMPP Extension Protocol 0033 (XEP-0033), which provides a method for both clients and servers to send a single stanza and have it delivered to multiple recipients. The benefit is reduced network traffic in situations such as multi-user chat and load balancing among clustered Jabber XCP routers.

* Auto-include Special Interest Groups (SIGs)/Schemas, which simplifies the job of developers by enabling new code to run on Jabber XCP without editing configuration files.

"Jabber XCP continues to lead with the world's most scalable, programmable, and interoperable messaging and presence platform," said Dave Uhlir, vice president of marketing and product management at Jabber, Inc. "Today's release is a significant milestone towards delivering a truly multi-protocol platform that can surpass a million concurrent SIP, XMPP, and/or IMPS users on modest hardware infrastructure."

"Most people are aware of presence information because of instant messaging. However, over the next several years, presence information will be used to identify when different types of resources including people, conference rooms, vehicles, deliveries, inventories, etc. are available, now or at an estimated time in the future," said Mark Levitt, vice president for collaborative computing and the enterprise workplace at IDC. "In preparing for this future presence-aware real-time work environment, organizations must look for a presence engine that has enterprise class reliability, scalability, security, and extensibility."
