Xilinx and Allegro Networks Collaborate on New Multi-Router Edge Network Technology

7/26/2002 - Xilinx, Inc. (NASDAQ:XLNX) announced that Allegro Networks, an innovative new edge networking supplier, utilized Xilinx® Virtex-II™ Platform FPGAs in the development of the industry's first multi-router. Allegro's multi-router is a new class of internetworking device that supports the concurrent operation and processing of multiple logically and physically independent routers within a single system. In addition to its own internally-developed ASICs, Allegro Networks selected Xilinx programmable chips to maximize flexibility and time-to-market benefits. Allegro Networks is among a growing number of companies using Xilinx FPGAs to gain a competitive advantage.

"We're building a system that has heretofore never been developed and set out on an aggressive schedule," said Dave Roth, engineering director at Allegro Networks. "We were confident in Xilinx's ability to meet their product road map commitments. As a result of our collaboration, we knew when selecting a certain device, a follow-on device would be there for future product development or enhancements."

In a break from conventional router technology, Allegro Networks' multi-router system provides numerous physical routers and associated route processors within a single system. This allows carriers to lower capital and operational costs at the edge of their network, optimize router provisioning and service delivery times and generate new sources of recurring service revenue. The multi-router utilizes Xilinx Virtex-II FPGAs throughout the system.

"We're seeing an increasing number of innovators such as Allegro Networks using FPGAs to maximize flexibility and reduce time to market. In the face of the current economic downturn, manufacturers are realizing that the high NRE cost and large development team sizes associated with other approaches are extremely prohibitive," said Robert Bielby, senior director of Strategic Solutions at Xilinx.
