Sun Adds Jabber Protocol to IM

Sun Microsystems announced its position in the instant
messaging (IM) protocol debate with its inclusion of the Jabber protocol in
the latest version of the Java System Instant Messaging application.

Officials at the Santa Clara, Calif., software company said version 7 of the IM platform now supports the extensible Messaging and Presence Protocol (XMPP) , often called the Jabber protocol because of its association with the open source instant messaging client.

Some heavyweight software developers, notably IBM and
Microsoft , have come down in support for a competing
specification called the Session Initiation Protocol for Instant Messaging
and Presence Leveraging Extensions (SIMPLE) .

Marcel Nienhuis, market analyst at the Radicati Group, said Sun’s backing of
the XMPP specification makes sense and evens out the playing field between
the two competing protocols, where SIMPLE is seen to have more corporate
backing. Sun’s decision to support XMPP, he said, also falls in line with
the company’s position as stewards of the Java platform.

“Sun’s whole message is open source and open systems, so it makes sense for
them to use the XMPP protocol,” he said.

Dan Graves, Sun group product manager for collaboration products, downplayed
that contention and said the decision to adopt XMPP was made primarily from
a features standpoint and in no way represents a decision to favor one IM
protocol over the other. Sun, he said, plans to address SIMPLE in the

For the three years leading up to the launch of Java System IM 7, Graves
said the company used a home-brewed protocol as a foundation for its
service before deciding to adopt one XMPP or SIMPLE. An analysis of the two
specifications found that XMPP was a better fit for Sun’s platform and its
customers right now, he said, with more third-party application adoption.

“The XMPP protocol was designed from the ground up to cover instant
messaging and collaboration, so it’s a lot broader and more complete in
terms of covering all the things you need to do, such that we can be full
standards-compliant and get full interoperability with other products,” he
said. “As opposed to SIMPLE, [where] companies have to extend it in various
different ways; those extensions end up not being interoperable, so you end
up with a situation where somebody’s flavor of SIMPLE doesn’t interoperate
with another vendor.”

According to Graves, Sun’s customer base includes approximately five to 10
million users under roughly 100 organizations.

With the inclusion of the Jabber protocol, Sun opens its Java Communications
Suite to other XMPP-based systems looking to interoperate their features on
the IM platform. Officials say XMPP support offers cost savings for their customers by expanding IM and presence functionality
through open source and third-party software applications.

They point to
Clique Communications, developer of a video communication and collaboration
tool application for mobile and landline networks, which will work on making
its product interoperable with Sun’s IM platform.

Enterprise IM is a topic of growing concern for companies worried about
communications between employees and the outside world, not the least of
which is exacerbated by federal regulatory scrutiny on document and
communications control.

An October 2004 report by Radicati found that 76 percent of organizations have not deployed a formal IM solution, a number that
Nienhuis said hasn’t changed much in the ensuing months.

Those surveyed that were using IM systems were using public ones like AOL’s
AIM service, Yahoo or Microsoft’s MSN

Plans by AIM and Yahoo to create secure enterprise versions of their consumer systems have fallen by the
; Microsoft’s enterprise IM solution falls under its Live Communications Server.

Enterprise use
of the consumer systems, Nienhuis said, leaves them vulnerable to a growing
number of nuisances like worms and spim and
phishing attempts.

“There have been all sorts of security problems with those products,” he
said. “I think what’s happening is companies are looking more and more into
the enterprise systems and into securing their own public IM networks with
[IM management companies] like IMLogic, Akonix and FaceTime.”
