NetXen Teams with Sigma Resources and Technologies to Deliver Enterprise Class Testing to Meet Fortune 500 Needs

Fully Automated Test Methodology Cuts Test Time by 50 Percent

Santa Clara, Calif. - February 19, 2008 - NetXen, Inc., the leader in multi-protocol 10-Gigabit Ethernet technology, and Sigma Technologies & Resources, a leading supplier of testing technologies for networking, security and wireless, today announced their collaboration on development of a best-of-breed test automation solution for testing NetXen's 10-Gigabit Ethernet Intelligent NIC?products. The new test methodology will enable NetXen to test hundreds of configurations in an automated test bed, which will shorten test cycles and improve product quality, reducing time to market. SigmationTF, Sigma's flagship product, is expected to be fully integrated with NetXen's live production network in 1H 2008.

"Working with Sigma has allowed us to create a powerful test automation infrastructure that cuts our test time dramatically, expands our test coverage and increases overall efficiency," said Walt Wallach, vice president of software engineering at NetXen. "Most test environments lack the power and flexibility needed to adequately test the range of operating system SKUs that are important for today's enterprise data center marketplace. Our automated approach to testing is more complete and faster than alternatives, which brings us tremendous advantages."

Industry analysts agree that enterprises want to control costs, maximize performance and deliver superior products and services. For companies with extensive test environments, working with a third party professional services team has proven to be a significant savings in engineering resources and lab and equipment requirements.

"SigmationTF helped NetXen automate more than 100 operating system variations, including all updates and service packs in two-thirds the normal amount of time," said Jia-Ru Li, Ph.D., vice president of technology of Sigma. "We are extremely pleased to be working with NetXen to extend their already significant test infrastructure to the next level with our automation technology; providing a competitive advantage to NetXen both in terms of time to market and quality."

The NetXen test infrastructure is based upon Sigma's SigmationTF software; a comprehensive test automation framework designed for testing TCP/IP based network products. SigmationTF automates running of tests to enable repeatable regression test methodologies that free test engineers from doing costly, time consuming, and error prone manual testing, and provides comprehensive reporting and archiving of test results. SigmationTF automates the large number of repetitive tests typically required during the test phase of the product life cycle, and later, the regression tests needed as software versions evolve.
