Santa Clara, CA, Apr. 28, 2003 - Bay Microsystems Inc., the leader in high performance Internetworking Processors and Traffic Managers, has won the EDN 2002 Innovation of the Year Award in the network processor category for Montego™, its single-chip OC192c/10G internetworking processor/traffic manager and ATM SAR. Sponsored by EDN Magazine, the Innovation Of The Year award recognizes and honors truly outstanding engineering products in the electronics industry introduced in calendar 2002.

"Being nominated for this EDN award is a credit to the outstanding engineering team we have at Bay," said Chuck Gershman, president and CEO of Bay Microsystems. "Winning the award is testimony to EDN's sophisticated readers recognizing a truly innovative 10G NPU, the only one of its kind deployed in a real-world network.
