F5 Networks Holds the No. 1 Market Share Position in the Layer 4-7 Ethernet Fixed Switch Market

SEATTLE--Nov. 29, 2005--

  With 47% Market Share F5 Experienced Highest Quarterly Revenue Growth Fueled by Sales of Its Unique BIG-IP Product, According to Dell'Oro Group Research  



F5 Networks, Inc. , the global leader in Application Delivery Networking, today announced its continued domination in the L4-L7 Fixed(1) Server Load Balancing (SLB) switch market. According to a recent Dell'Oro Group Report(2), F5's market share has grown to 47 percent, positioning the company as the clear market leader over Cisco and Nortel.

The market reaction to BIG-IP v9 and F5's unique TMOS architecture has been very positive. That, combined with continued strength of F5's iControl partnerships, helped drive almost 50% of F5's product revenue in the past quarter. In addition, the increasing sophistication of F5's unique iRule application development capability has insured the company's continued successful penetration into larger enterprise accounts and service providers.

"The main reasons F5 continues to grow its revenue in this market over the competition is due to the BIG-IP product's unmatched full proxy architecture, iRule intelligence, application security and acceleration capabilities," said Dan Matte, SVP of Marketing at F5 Networks. "F5's BIG-IP product enables customers to automate functions that previously would have to be done in the application itself, saving them significant development and management costs."

About the BIG-IP Product

Located in the data center in front of servers, firewalls and gateways, F5's BIG-IP allows organizations to extend the benefits of Application Delivery Networking to all of their IP-based applications. Application Delivery Networking allows organizations to ensure quality of service and manageability, apply business policies and rules to content delivery, support increasing traffic volumes, deliver their applications securely, enjoy operational efficiency and cost control, and remain flexible to future application and infrastructure changes to protect their investments. F5's iRules, integrated with BIG-IP and the TMOS platform, allows customers to offload critical functions from applications and run them more efficiently within BIG-IP. F5 recently showcased the power of iRules by launching the "iRule, Do You?" contest. For more details on the results visit http://devcentral.f5.com/Default.aspx?tabid=72.
