SEATTLE -- F5 Networks, Inc. (NASDAQ: FFIV), the leading provider of Internet Traffic and Content Management (iTCM) products, today announced that F5 has posted the highest quarterly revenue growth of any vendor in the Layer 4-7 (L4-7) Fixed Server Load Balancing (SLB) switch market. This represents an increase of 89 percent over the last quarter ending March 31, 2002, according to the recent Dell’Oro Group Report. Additionally, F5 has experienced the largest gain in market share over the last quarter, capturing 15 percent of the L4-7 SLB switch market within just 8 months. "When we announced our IP Application Switch family we knew that the technology would be a market disrupter due to its optimized, all-in-one architecture with centralized processing, switch fabric design, and integrated SSL," said Dan Matte, vice president of product management and marketing at F5 Networks. "Customers have enthusiastically embraced F5’s application switches because they clearly outclass the competition and offer an adaptive solution that can evolve with the demands placed on enterprise and service provider networks - saving considerable time and money. We’re particularly pleased with our growth in market share to 15 percent, since we just began shipping the BIG-IP 5000 eight months ago and the BIG-IP 2000 five months ago." The Dell’Oro Report measured market share based on revenue attainment for all the major Layer 4-7 SLB switch manufacturers. According to the Dell’Oro Report, sales of F5’s BIG-IP Application Switches grew to $9.1 million for the quarter, representing an 89 percent growth in revenue over the previous quarter. Of the top four vendors measured in the report, F5 posted the largest gain in market share based on revenue. Besides F5, only one of these four vendors increased its revenue, while the others decreased. The report also reveals that F5 has achieved the greatest increase in market share, up 6.5 percent, over the last quarter.F5 Networks Inc.Dell'Oro Group
