“For more than a decade Spirent has pioneered advancements in Ethernet testing and we are delighted to see our leadership position validated by our customers through Frost & Sullivan’s research,” said Bill Burns, CEO, Spirent. “As the industry migrates to ever more complex technologies, we remain focused on delivering world-class products that enable our customers to rapidly deliver new solutions and services.”

This award underscores Spirent’s unmatched Ethernet testing expertise that extends from the lab with product development and verification, to the field for service assurance and to the in-home network to ensure Quality of Experience (QoE) of multiplay applications. Spirent’s Ethernet lab solutions including its flagship product - Spirent TestCenter (TM), and service assurance tools such as Spirent Tech-X Flex, have been designed to test high-speed communication networks that deliver rich media content.

As the industry migrates to 40/100 Gigabit Ethernet networks that support high bandwidth applications, addressing realism will be critical to ensuring service QoE. The emphasis on realism is the reason why service providers and equipment manufacturers across the globe depend on Spirent to address the complexities of high-speed Ethernet testing.

“It is no longer enough to offer test tools that focus solely on performance,” said Jessy Cavazos, industry manager, Measurement & Instrumentation, Frost & Sullivan. “Instead, network equipment vendors and service providers are demanding test solutions that offer enhanced realism as they scale their products and networks. Spirent stands above the crowd in terms of delivering the realism, scalability and the intelligent results required by customers testing Ethernet solutions today.”

Spirent was also recently recognized by Frost & Sullivan as the market leader for enterprise network test and measurement solutions. In addition, it has received numerous other accolades including Test & Measurement World’s 2009 Best in Test Award, and the NGN Leadership Award 2009.
