"The BIG-IP systems are a huge competitive advantage for us, because they help us provide a better customer experience," Manzoori said.

F5 Networks claims its BIG-IP systems can help reduce page download times by more than 200 percent, and decrease bandwidth usage by 60 to 80 percent.

"For our developers, the BIG-IP systems proved to be straightforward to install into the network," Manzoori said. "They are also fairly easy machines to run and have a GUI that allows them to be managed remotely."

Dan Matte, F5 Networks' vice president of marketing and business development, said the company has been successful at the level above the infrastructure layer where there is "more intelligence" in the network.

Matte attributes much of F5's growth to a drive to consolidate infrastructure and a need to better look at the network.
