Santa Clara, CA, Oct. 20, 2003 - Bay Microsystems Inc., a leader in high performance network processing, today announced availability of an interoperability solution with Applied Micro Circuits Corporation (AMCC) products showing, for the first time, a complete system performing 10 Gbps internetworking, traffic management and switching using the Network Processor Forum's standard Common Switch Interface Consortium (CSIX) interface.

Bay's Montego™ Internetworking Processor and AMCC's PRS Q-64G Switch Fabric seamlessly perform line-rate 10 Gbps (OC-192) SAR, traffic management and switching between multiple sources, including IP and ATM. Bay's Internetworking Development System (IDS) powered by Montego has line cards with seamlessly integrated AMCC PRS C192 fabric interface devices connected over a standard CSIX interface. Multiple IDS systems directly connect, at rates of 16Gbps, with AMCC's PRS Q-64G switch reference platform. The solution highlights Montego's complete traffic management capabilities, which include support for 4096 Virtual Output Queues (VOQ) with flow control, multicasting, fine grained traffic shaping, scheduling for tens of thousands of queues, SAR, and flow-based classification, all at full line rate.

"This solution represents much more than just vendor to vendor interoperability. The IDS systems are currently deployed within our customers' mission critical secure networks," said Chuck Gershman, president and CEO of Bay Microsystems. "With the combination of Montego and the PRS, our customers now have a leading-edge, network verified solution for implementation within their high performance networking platforms."

Interoperability with the leading network system OEM platforms has been demonstrated within Service Provider networks for this complete seamlessly integrated solution. Design reference materials available from Bay include Application Notes, Bill of Material (BOM), schematics, mechanical drawings, artwork, advisory notes and more.
