Extreme Networks Demos Production 10 Gigabit Ethernet Infrastructure for Next Generation Network Services at Sun Conference

Extreme and Sun Offer Optimal Performance for Applications at SunNetwork 2002

SANTA CLARA, Calif., Sept. 20, 2002 --Attendees at this week's SunNetwork 2002 saw first-hand next generation network services across a production 10 Gigabit Ethernet infrastructure in the Extreme Networks, Inc. (NASDAQ: EXTR) booth (Moscone Center, booth P49). The 10 Gigabit backbone demonstrated offers advanced Quality of Service (QoS), security and resiliency features, such as Ethernet Automatic Protection Switching (EAPS), and is being used to provide 10 Gigabit Ethernet connectivity for the Sun Microsystems Sun Ray(TM) Thin Client enterprise system running the StarOffice(TM) application suite.

Extreme Networks' 10 Gigabit infrastructure allows very high performance applications such as the Sun StarOffice suite to effectively use maximum available bandwidth without encroaching on resources available for other applications. By providing a reliable, ultra-high bandwidth foundation for advanced applications, the availability and response time can be dramatically improved across the network. This enables users to benefit from the productivity enhancements offered by advanced applications that are frequently not realized because of inadequate infrastructures.

Extreme Networks' 10 Gigabit infrastructure provides a beneficial underpinning to computing-intensive environments, such as Sun Microsystems' GRID computing architecture, which provides a high-performance clustering environment for a variety of applications, including life sciences, and oil and gas seismic tasks -- all of which are being demonstrated at SunNetwork 2002.

"The SunNetwork Conference provides an exceptional opportunity for customers to see solutions upfront," said Duncan Potter, vice president marketing for Extreme Networks. "We demonstrated maximum scalability with 10 Gigabit technology to show Sun users how to leverage our simplified network platform for improving their productivity and reducing costs."

Industry Tested and Proven 10 Gigabit Technology

Two recent reports from the premier independent test house, The Tolly Group, found Extreme Networks' BlackDiamond(R) 10 Gigabit solution delivers superior performance and provides a more comprehensive solution than those from Cisco Systems and Foundry Networks. The reports state that the QoS and traffic filtering functions on the Extreme Networks 10 Gigabit switch enable network managers to make the most efficient use of bandwidth. In addition, the reports find that the Extreme Networks solution provides a higher throughput than the Cisco 10 Gigabit solution. The Extreme 10 Gigabit solution also stands apart from both the Cisco and Foundry 10 Gigabit solutions because of Extreme's capacity to effectively manage QoS traffic priorities across a 10 Gigabit uplink.

The reports conclude that the Extreme solution "goes a step beyond in performance."
