Allied Telesyn AT-8126XL Managed Fast Ethernet Switch Outperforms the Competition in Independent Testing.

LAS VEGAS--(BUSINESS WIRE)--May 12, 1999--

Compared against three other leading commercially-available

24-port Layer 2 switches, the AT-8126XL is the performance leader

Allied Telesyn International (www.alliedtelesyn.com), a worldwide leader in simplifying networking for businesses of all sizes, is pleased to announce today that results of independent laboratory testing (http://www.svnl.com/test_lab_reports.htm) show that Allied Telesyn's AT-8126XL managed 10/100TX switch out performs the leading competition in the 24-port Fast Ethernet switch category.

The testing, performed by The Silicon Valley Networking Lab, Inc. (SVNL) www.svnl.com, compared four market-leading switches: the Cisco 2924XL, the 3Com 3300, the NBase NH2025-GE, and the Allied Telesyn AT-8126XL. When testing was completed, the results showed the Allied Telesyn AT-8126XL switch to be the top-performing switch in its class.

SVNL's tests benchmarked performance of the switches using the RFC 1944/2285 performance suites, as well as by running simulated enterprise applications.

"Our comprehensive testing clearly shows that the Allied Telesyn's AT-8126XL performs as good as or better than those products considered best in class," said Steve Bell, CEO of The Silicon Valley Networking Lab.

Sean Keohane, Senior Vice President of Sales and Marketing for Allied Telesyn, believes that the results from these independent tests speak volumes for Allied Telesyn's switch capabilities.

He said: "Our confidence in this switch as a top performer has been strong from the start and this objective testing now proves it. Combine that proven superiority with the fact that the AT-8126XL costs considerably less than the competitors it out performed, and you have the best value proposition around for this class of product."

In each of five sets of standardized tests (IETF RFCs), Allied Telesyn's AT-8126XL came out on top as the performance and accuracy winner. The managed Fast Ethernet 8126XL switch demonstrated 100% throughput, consistently low latency across all loads (noted as great for voice and video applications), showed no frame loss for all packet sizes, and met tester expectations in HOL blocking tests for frame loss.

In the final standardized test, the full-meshed traffic test, which combines all of the preceding factors into general performance, the AT-8126 "clearly out performed" the other commercially available switches, according to the report.
