Today's focus: ClearSight helps predict performance
By Denise Dubie
Network analysis tool provider ClearSight Networks this week is
set to ship a product designed to help network managers test
their nets and measure their performance potential under heavy
loads.
ClearSight Packet Generator is software loaded onto a Microsoft
Windows 2000 or XP laptop that lets network managers simulate
network traffic and get an idea of how the network would behave
under certain conditions. The software can work with ClearSight
Analyzer software or independently to send packets over a
network and test how well the network responds.
With Packet Generator, the packet size and content of a single
packet can be set and the packet sent repeatedly at a specified
rate. Also, ClearSight says, the transmission rate can be set in
terms of the packet interval or network utilization.
The product helps network engineers determine how changes in
traffic load, network design or end-user demands will affect
overall performance, according to one user.
Matt Holbert, principal technologist for Network Government
Services, in Herndon, Va. (with a data center in San Diego at
which Holbert works), says he started using Packet Generator
about a month ago to test the affect of different traffic loads
on the company's production network. The firm helps customers
such as the Department of Defense and the Bureau of Alcohol,
Tobacco, Firearms and Explosives transform the organizations'
networks into secure and easily managed systems.
"We were looking to be able to model real-world network traffic
in a lab environment that mimics our production environment to
test performance," he says. "Basically you do a capture and
retransmit the traffic, and it does it at a reasonable price."
ClearSight competes with the likes of Spirent and Ixia in terms
of simulate packet generation and traffic analysis. But
ClearSight CEO and Chairman Bill Berkman says his company
provides the technology for less cash.
"The price is less because ultimately we don't target equipment
manufacturers or carriers like some of our competition. Our
customer is the network manager in an enterprise company,"
Berkman says.
ClearSight Packet Analyzer is available now and costs just under
$2,000.
