Extreme Networks BlackDiamond 12804 Switch Validated with Avaya’s Market-Leading IP Telephony Solutions


New switch evaluated for key requirements that enable a foundation for a converged network infrastructure—leveraging performance and an open approach

16-Aug-2006 - SANTA CLARA, Calif. – Extreme Networks Inc. (Nasdaq: EXTR) and Avaya (NYSE: AV), a leading global provider of business communications applications, systems and services, have successfully completed testing of Extreme Networks’ BlackDiamond® 12K switch with Avaya IP telephony solutions. The companies evaluated performance, scalability and resiliency of the switch in converged Ethernet networks using multiple switching domains and protocols.

The BlackDiamond 12804 was successful in all tested scenarios, interoperating with Avaya Communications Manager IP telephony software, Avaya Media Gateways and Avaya IP phones. As a result, the BlackDiamond 12804 switch was validated as compliant through Avaya’s DeveloperConnection program—an initiative to develop, market and sell innovative third-party products that interoperate with Avaya technology and extend the value of a company’s investment in its network. Extreme Networks is a strategic member of the program.

The BlackDiamond 12804 switch passed 20 of 20 interoperability test scenarios. Highlights of the tests include:

* Fast convergence and enhanced network resiliency and service recovery with Multiple Spanning Tree Protocol (MSTP) and multiple Ethernet automatic protection switching (EAPS) domains, in under 50 milliseconds.
* Network scalability using Provider Bridging (standardized as IEEE 802.1ad) and Provider Backbone Bridging (being standardized as IEEE 802.1ah) to extend enterprise connectivity virtually across multiple locations. This test demonstrates preservation of virtual local area networks (VLANs) and traffic priority across multiple connected sites.
* Quality of Service (QoS) for applications with interoperability of 802.p/Q priority packets at Layers 2/3, and VLAN support with 802.1x authentication for data and voice traffic.

“With these tests, the BlackDiamond 12804 switch is proven to deliver critical voice and data convergence with Avaya’s world-class IP telephony solutions, enabling customers to build a resilient and reliable voice and data network,” said Suresh Gopalakrishnan, vice president of marketing and product management for Extreme Networks. “Our open networking approach, consistent performance and the use of emerging technologies, including Provider Backbone Bridging for network scaling, provide valuable benefits as tested and proven with Avaya.”

“Avaya promotes fully interoperable solutions that help businesses unleash powerful new possibilities, helping them get more out of their network investment and delivering new value to their bottom line,” said Eric Rossman, vice president, developer relations and technical alliances, Avaya. “The successful compliance-testing of Extreme Networks’ BlackDiamond 12804 switch showcases how a best-in-class, converged multivendor network can deliver full-featured enterprise applications across the breadth of an organization—enabling employees and customers to access information from wherever they are, over whatever device they have available.”

As a member of the Avaya DeveloperConnection program, Extreme Networks is eligible to submit products for compatibility testing by the Avaya Solution Interoperability and Test Lab in Lincroft, N.J. There a team of Avaya engineers develops a comprehensive test plan for each application to verify whether it is Avaya compliant. Doing so ensures businesses can confidently add best-in-breed capabilities to their network without having to replace their existing infrastructure—speeding deployment of new applications and reducing both network complexity and implementation costs.
