WESTFORD, Mass. – Jan. 20, 2011— NetScout® Systems, Inc. today announced that independent research firm Frost & Sullivan has named NetScout Adaptive Session Intelligence™ (ASI) technology as the Global 2010 Enabling Technology of the Year for Network Performance and Application Monitoring. The award recognizes NetScout as setting new industry standards for innovation and leadership with the introduction of a transformative Deep Packet Analysis (DPA) engine that dynamically tracks, captures and analyzes user-level transactions across multi-domain IP networks. The highly scalable and comprehensive visibility from by ASI technology will enable a more unified end-to-end view of user experience and speed the identification, triage and resolution of performance problems across highly complex distributed service delivery architectures, such as cloud-based services, virtualized applications and distributed transaction-based applications. “We chose NetScout ASI technology for the Global 2010 Enabling Technology of the Year Award for its innovative approach in addressing the challenges of service delivery management in multi-tier, multi-domain environments,” said Olga Yashkova, Program Manager, measurement & instrumentation, Frost & Sullivan. “The ASI technology also demonstrates exceptional vision in the protection of customer investments by adapting the new technology across existing nGenius® Service Assurance Solution analysis modules. Clearly, NetScout is providing the leadership that IT organizations need to manage the fast-changing technology revolution in service management approaches.” Each year, Frost & Sullivan presents this award to the company that has developed a pioneering technology that not only enhances current products, but also enables the development of newer products and applications. This award recognizes the high market acceptance potential of the recipient's technology. Frost & Sullivan's Best Practices Awards recognize companies in a variety of regional and global markets for demonstrating outstanding achievement and superior performance in areas such as leadership, technological innovation, customer service and strategic product development. Frost & Sullivan industry analysts compare market participants and measure performance through in-depth interviews, analysis and extensive secondary research in order to identify best practices in the industry. “We are extremely honored to have received this recognition for our technology innovation and vision from Frost & Sullivan,” said Steven Shalita, vice president of marketing, NetScout. “Throughout our 26-year history, NetScout has remained focused on driving innovative and scalable ways to address the challenges of service management by leveraging the value of information from network traffic. Our vision for ASI technology will help organizations to address the inherent scalability and visibility challenges of next generation IP technologies and enable a more business-oriented view into user experiences. NetScout ASI technology transforms the power and analysis velocity of the nGenius Service Assurance Solution’s Deep Packet Analysis capabilities. Using adaptive application recognition, ASI technology constructs “intelligent signatures” of user sessions to fully visualize all of the transactions occurring within a specific session for unprecedented visibility into complex multi-tier, multi-domain service delivery environments. The new intelligent metadata of every transaction and the associated user experience enables a more scalable approach to analyzing and storing high volume IP traffic, which is necessary for emerging technologies such as 40 and 100 Gigabit Ethernet interfaces and IPv6. ### About NetScout Systems, Inc.
