                   OPNET's Guru Software Leverages Accurate

       Real-time Performance Information from NetScout's nGenius System

BETHESDA, Md., and WESTFORD, Mass., Dec. 10 /PRNewswire/ -- OPNET Technologies (Nasdaq: OPNT) the leading provider of intelligent network management software and NetScout Systems' (Nasdaq: NTCT), the leading provider of network performance management solutions today announced new integration between the two companies' network management offerings. The new solution provides enterprises a means of automatically integrating the real-time performance information generated by NetScout's nGenius(TM) System into OPNET 8.0 Guru products.

"Both OPNET and NetScout are first class technology companies in the network management industry," said Mr. Masaaki Miura, General Manager at Mitsui. "The combination of their newest product offerings -- real-time traffic information from NetScout's nGenius Real Time Monitor(TM) and the new flow analysis technology from OPNET 8.0 -- offers a compelling value proposition for enterprise network managers worldwide."

OPNET's award-winning products provide a virtual network environment in which to analyze and optimize network applications, configurations, and traffic flows in a nearly limitless range of "what if" scenarios. NetScout is the market leader in generating comprehensive, real time views of the network and its traffic flows, which generates critical decision-making information for network management, such as the effects of individual application flows and conversations on network resources, slowdowns or loss of networked services, and performance inefficiencies resulting from problematic network architectures and applications. By integrating NetScout performance information with OPNET products, users can enhance the results of their modeling projects with live statistics from their own networks -- system-wide and on a segment-by-segment basis.

OPNET's Guru products automatically generate and populate network models using live network information. The process of importing live network information into OPNET's virtual environment immediately identifies problems such as application inefficiencies and network addressing conflicts. By simulating changes such as technology migration, traffic growth, and failures, OPNET users can fix existing performance problems with additional confidence, and solve new problems before they occur.

Unlike other management approaches that approximate network health using infrastructure device data and events only, NetScout's new nGenius Performance Management System delivers detailed performance information generated by dedicated information appliances that measure the actual behavior of the network in delivering business applications to individual users. The appliances continually monitor critical network traffic flows, ensuring constant visibility into high value links and traffic system-wide, through nGenius performance management applications.

"We look forward to a strengthened relationship with NetScout Systems. Our customers will realize better ROI by incorporating accurate, real-time traffic flow information from nGenius into their OPNET projects," stated Marc Cohen, Chairman & CEO of OPNET. "Existing NetScout customers will benefit from the opportunity to use their nGenius information for valuable new forms of analysis provided by OPNET."

Michael Szabados, NetScout's senior vice president of product operations, added, "This is a significant extension of our ongoing relationship with OPNET. Our traffic-centric performance management information reveals live use of the network, the essential ingredient for accurate baselining and analysis of network behavior. Our relationship with OPNET illustrates the value of our nGenius information in state-of-the-art solutions produced by leading network management companies."


The Multi-Vendor Import (MVI) Module for OPNET 8.0 products now supports the nGenius Performance Management System. OPNET's SP Guru product, which includes MVI functionality, now also supports the nGenius import enhancement. For more information, please contact OPNET Sales at info@opnet.com.
