Today's focus: Karalon tackles network traffic jams

By Denise Dubie

Traffic jams tend to be one of the most irritating occurrences
in day-to-day life - and I am not just referring to cars on the
highway.

Traffic congestion on networks can be the source of many
performance problems and is often difficult to remedy with
network management tools that poll.

According to AT&T Labs Research, network modeling and
measurement tools could better address traffic jams on IP
networks and help network managers route traffic for optimal
performance.

"Network managers need better tools to support measurement and
modeling if they are to effectively manage traffic flow, routing
policies and network configuration," states an online AT&T Labs
Research report. In addition, "It's not always possible to
provision new resources - for example, high-speed interfaces -
to meeting changing demands," writes Albert Greenberg, AT&T Labs
researcher, in the online report.

A product set to debut next week from U.K. software maker
Karalon attempts to address the issues around traffic management
and proper network testing. Traffic IQ is software that runs on
Windows and is designed to help network and security engineers
perform protocol analysis on network and security devices. The
software uses two network cards on the same PC or laptop to test
the devices, the company says.

The software - which comes in two flavors, Basic and Pro - uses
predefined traffic files to test firewalls, intrusion prevention
and detection systems, anti-virus tools, routers and switches.
The software also includes a feature to let network managers
replay "normal and malicious network traffic," the company says,
and as well as tools to play, pause and stop traffic streams in
real time.

Traffic IQ Basic has a library of 58 traffic files and is priced
at $299 for a single annual license. Traffic IQ Pro has an
updated library, more than 640 traffic files, and is priced at
$4,800 for a single perpetual license including first year's
maintenance and support.
