SANTA CLARA, Calif. -- Bay Microsystems, a leader in high performance packet processing, today announced BiscayneÔ, a programmable classification processor that can parse, classify and police packets and cells at rates up to 16 Gbps, at minimum packet size regardless of traffic patterns. At 16Gbps for both ingress and egress, and with power dissipation of only four watts, Biscayne is the industry’s lowest power classification processor.

Biscayne connects seamlessly to Bay’s other Internetworking Processor™ (InP) products, including Montego™, a single chip OC-192c/10G programmable internetworking processor, traffic manager and SAR. Based on the same deterministic, superscalar, pipelined architecture as Montego, Biscayne’s classification and policing functions support a wide range of existing and emerging applications, including Ethernet, IPv6, IPv4, ATM, Packet over SONET, Frame Relay, MPLS and DiffServ.

Biscayne’s unique features include dedicated policing algorithms, such as Committed-Max-Excessive, Dual Token Bucket, and Dual Leaky Bucket, thus supporting Ethernet/Frame Relay, DiffServ and ATM policing. This industry-first policing support allows for policing on a flow or tunnel/trunk basis. Additionally, Biscayne supports Quality of Service (QoS) internetworking, which allows for programmable conversion from any QoS mark to any other QoS mark. Therefore, QoS marks may be translated between protocols by user-defined rules and relative QoS values may be retained across disparate networks.

With this breadth of service support, Biscayne preserves investments in legacy equipment and enables new profitable services within the same equipment. While other classification processors only support parsing and classification tagging, Biscayne also enables modification functionality as well, making it an attractive option for cost-sensitive applications such as access enterprise equipment.

According to recent market research, Ethernet is becoming ubiquitous across most metro and transport platforms, with metro Ethernet switching projected to top $3 billion by 2006, according to Infonetics Research (San Jose, CA). Biscayne enables this market with support for features such as fast path MAC learning and aging, L2VPN, L3VPN, VPLS, VLANs with multiple domains, and more. Additionally, with the proliferation of wireless devices driving the need for more addresses and the US Government requiring IPv6 support, IPv6 is gaining traction. Biscayne addresses the needs of IPv6 enabled switches and routers, including header popping for tunnel termination.

"Bay Microsystems was the first to deliver a single chip 10G network processor, traffic manager, and SAR, and it has now unveiled the industry's fastest classification processor," said Bob Wheeler, senior analyst at The Linley Group. "The combination of Biscayne and Montego should be attractive for deeply encapsulated metro applications. Bay's solution also offers excellent time-to-market through greatly simplified software development."

“Biscayne is another example of the superior Bay technology, which not only satisfies the current market requirements of our existing clients, but grows a family of products that spans a multitude of enterprise and carrier applications from access to long-haul,” said Chuck Gershman, president and CEO of Bay Microsystems. “As we emerge from this long harsh market downturn, only the companies that can enable a wide range of market segments will thrive.”

For high performance applications, Biscayne enhances the classification capabilities of a downstream network processor/traffic manager, while providing direct physical and messaging-based interface between the two devices. With Biscayne, network systems OEMs can accomplish more complex tunnel resolution and routing for products such as multi-protocol edge routers and voice/wireless gateways. Biscayne is capable of classifying extra long headers, such as IPv6; larger stacks of label swapping protocols, such as MLPS; and highly complex and deeply embedded multi-field headers, such as VLAN/SNAP, IPv6/IPv4. In addition, OEMs can now support applications for Ethernet bridges/switches, VLAN forwarding, IETF PPVPN (VPLS, L2/L3VPN), MPLS, VLAN to MPLS mapping, IETF PWE3 (ATM and Ethernet PR tunneling), Legacy UNI (Frame Relay and ATM), and more.

Biscayne supports flexible packet parsing and key generation with direct interfaces to TCAM and SRAM search memories to support more than 400 million searches per second. Use of external memories allows the user to scale the memory to the application, enabling system cost to map directly to performance requirements. Biscayne interfaces to any SPI-4.1, SPI-4.2 or SPI-3 compliant device, thus supporting OC-48 and OC-192 applications.

Bay’s robust simulation and emulation design environment, called the Internetworking Development System (IDS), fully supports Biscayne. It includes Java GUIs, CLI, NextwareÔ API, System Administration Server (SAS), Intermodule Communication, Vxworks OS, Board Support Package (BSP), Diagnostics, TCP/IP Stack and Drivers. The Nextware software programming environment uses a cycle/pipeline accurate C-simulator for quickly applying, verifying and debugging application examples for any traffic pattern and network service.

Biscayne will be available in 166 MHz and 100 MHz versions and priced below $300 in volume quantities. Samples will be available in 1Q04 in an 1156 BGA package.

In a separate release:

Bay Microsystems Inc., a leader in high performance packet processing, today announced availability of an interoperability solution with Applied Micro Circuits Corporation (AMCC) products showing, for the first time, a complete system performing 10Gbps 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 10Gbps (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.
