Business Editors/High-Tech Writers

SAN MATEO, Calif.--(BUSINESS WIRE)--Feb. 11, 2004

ClearSight Networks, the first company to offer network analysis tools for troubleshooting at the application layer, today announced ClearSight Analyzer 3.1. Well-received by government and corporate customers at launch in October 2003, this upgrade of the ClearSight Analyzer product line addresses customer demands by providing a clear migration path to replace legacy analyzers with a ClearSight next-generation application analyzer.

The ClearSight product line includes ClearSight Analyzer, ClearSight Analyzer 10/100 Full Duplex, ClearSight Analyzer Gigabit and ClearSight Remote. These application troubleshooting tools support the same breadth and depth of networking protocols as traditional analyzers, including analysis on the physical layers of the network: yet, the intuitive depiction of the application conversations, along with the comprehensive flow analysis goes far beyond the capabilities of historic analyzers. Using ClearSight, IT administrators can see exactly what the user sees during network and application problems. This enables employees across disciplines to quickly pinpoint network problems in real-time, leading to more effective use of resources and high availability of business critical applications.

"ClearSight Analyzer helps our IT department maintain network control and optimal performance. The product is very intuitive; its diagrams make problems immediately evident and familiarity with application-specific codes is not necessary," said Burt Bennett, general manager of Valparaiso Broadband Communication Systems. "ClearSight provides us with the customer support we need, and it's clear our feedback helps affect the features included in new version releases."

New feature upgrades in ClearSight Analyzer 3.1 include:

-- Gigabit Auto-negotiation decode enables ClearSight Analyzer

users to view the way in which network devices communicate.

This feature helps IT administrators to observe and

troubleshoot the way Gigabit Ethernet devices mount Gigabit

Networks, set each media speed and determine half/full duplex

capabilities.

-- Auto-save provides automatic save functionality that does not

require the Analyzer operator to perform a save before

shut-down. Also, if the Analyzer is run for a long time (over

a weekend), a trace will be saved automatically even when

capture buffers become full.

-- Triggers allows IT administrators to perform an action (start,

stop capture, etc.) when an event occurs. This feature is a

set and forget feature -- it means less operator management of

the Analyzer.

-- Updated decode engine delivers up-to-date support for a number

of newer protocol standards, including VoIP, IPv6 and routing

families. This enhancement enables users to troubleshoot the

latest emerging communication standards.

-- Ladder Diagram Printing allows real-time diagrams to be

captured in hard copy so that administrators can keep a record

of common challenges and recurring problems. The Ladder

Diagrams enable sharing of application troubleshooting

information between disparate IT groups.

"Product development has been working tirelessly to incorporate enhanced features and continue to build on the momentum from our recent company launch," said Tom Orr, ClearSight CEO. "ClearSight is committed to providing superior application and network troubleshooting tools and the swift release of ClearSight Analyzer 3.1 further demonstrates our aggressive growth plan for 2004."

Promotional discounts on all products will be offered through March 2004. A fully functioning version of the product is available for download at http://www.clearsightnet.com/form-downloadtrial.jsp
