WESTFORD, Mass., August 1, 2005 – NetScout Systems, Inc. (NASDAQ: NTCT), a leading provider of network and application performance management solutions, today announced that the Shanghai Futures Exchange has deployed its nGenius® Performance Management System to help optimize the performance of time-sensitive trading and back-office applications, which handle more than a trillion dollars (more than 8 trillion Chinese yuan) in futures contracts annually.

The Shanghai Futures Exchange (SHFE) is a self-regulated, non-profit organization, providing the facilities and services for centralized trading of futures contracts in the People’s Republic of China. Its approximately 220 members, mostly futures brokerage firms, rely on the exchange’s state-of-the-art electronic trading systems and networks to conduct rapid trading on commodities such as copper, aluminum and natural rubber. The SHFE network combines high-capacity fiber optic and data links with a satellite network to support front-end operations, deliver financial data, and execute orders from the SHFE trading floor in Shanghai as well as its 250 remote sites throughout the People’s Republic of China. The futures exchange trading platform is the core of the institution’s operations. Any degradation in its performance could interrupt trading and damage the exchange’s reputation.

SHFE’s IT staff investigated solutions that would provide effective network and application monitoring of the trading platform and its underlying networks. The exchange selected NetScout’s nGenius System for its comprehensive network and application visibility, capacity planning and advanced reporting capabilities, all of which have improved IT staff efficiency and operational cost savings.

The nGenius System provides SHFE’s IT staff with immediate access to detailed statistics to troubleshoot potential problems impacting the performance of the time-sensitive trading applications. SHFE uses the nGenius System’s response-time measurements to provide alerts of application slowdowns and facilitate rapid troubleshooting to pinpoint the source of problems, such as abnormal traffic caused by a virus outbreak or declining responsiveness of a trading server caused by too many simultaneous client connections.

“The nGenius System helps us quickly determine whether there actually is a real problem, whether it is a network or server issue, and where and when it occurs, so we can eliminate it with minimal impact to trading services,” said Mr. Kuang Jiaxing, director of the IT department at the Shanghai Futures Exchange. “We have been able to achieve more efficient IT operations and protect the exchange’s reputation with optimal performance of our network and trading applications.”

Another major benefit of SHFE’s nGenius deployment is more accurate capacity planning from its ability to track and report on remote site and link activity. The nGenius System’s customizable and easy-to-use reports feature rich historical information to enable business-oriented capacity planning, as well as response-time measurements, the number of users or remote clients connected to a server, and the connection time of the clients. The nGenius Performance Manager NewsPaper reports can be tailored to address the needs of the different audiences throughout the exchange, as well as provide visible proof of network performance.

“The fast pace of the Shanghai Futures Exchange’s trading operations places high demands on its networked applications and expert IT staff,” said Jim Frey, NetScout’s vice president of marketing. “The exchange’s successful deployment of the nGenius System is a testament to the value that NetScout solutions bring for real-time troubleshooting of business-critical applications and strategic resource planning in the complex financial networks that support split-second trading decisions.”
