Cavium Networks Works With Broadcom to Offer Comprehensive Set of Intelligent Switching Reference Designs

Cavium Networks (NASDAQ: CAVM), a leading provider of highly integrated semiconductor products that enable intelligent processing for networking, communications, storage and security applications today announced a comprehensive set of reference designs targeted at intelligent switching and broadband applications. These reference designs will utilize Cavium's market-leading OCTEON Multi-core MIPS64® processor family along with Broadcom's widely adopted enterprise class StrataXGS® and home/SMB ROBOSwitch(TM) Gigabit Ethernet switches, and FASTPATH® networking software. The reference designs aim to reduce engineering development cost and time-to-market for intelligent enterprise switches, Layer 4+ switches, and SOHO/SMB routers.

Today many OEM customers use a combination of Cavium's OCTEON processors and Broadcom's switches in their designs. Each OEM customer has to independently perform hardware and software integration and validation of the combined Cavium and Broadcom solution. This hardware and software integration consumes precious research & development resources, increases the engineering development time, and may not optimally use all of the advanced capabilities available in Cavium's OCTEON processors and Broadcom's StrataXGS and ROBOSwitch families.

The scalable set of reference designs using Cavium and Broadcom silicon addresses the need for pre-integrated, optimized, and validated reference designs addressing enterprise and SMB/home markets.

Enterprise Class Reference Designs

To enable tightly integrated design with seamless interoperability, Broadcom has licensed its HiGig(TM) protocol to Cavium Networks. The HiGig protocol enhances Ethernet switching beyond industry standards with features such as stacking and QoS. Cavium Networks' recently-introduced OCTEON processors and follow-on processors with 10Gigabit interfaces integrate hardware acceleration that supports HiGig protocol and enable intelligent switching applications. Additionally Broadcom will utilize Cavium OCTEON processors in its enterprise reference designs as a control plane and services processor, supporting the complete portfolio of StrataXGS Ethernet switches, which are industry-leading, widely deployed merchant silicon switching solutions.

SMB/Home Reference Designs

Broadcom is also utilizing Cavium OCTEON processors in its SMB switching reference designs as a gateway host processor combined with Broadcom's ROBOSwitch Gigabit Ethernet Switches and FASTPATH networking software.

"We are seeing the rapid adoption of gigabit connectivity with the need for intelligent services at line-rate in both enterprise and SMB/home networks," said Martin Lund, vice president and general manager Network Switching Business Unit, Broadcom Corporation. "Major networking and wireless OEM customers have chosen Broadcom's switches along with Cavium's OCTEON processors. Through our work with Cavium we will enable the quick deployment of intelligent services with the highest performance for our mutual customers."

"Customers are looking for processor solutions that scale from home/SMB to enterprise-class performance with software compatibility and enable intelligent and secure services for converged voice, video and data networks," said Syed Ali, president and CEO at Cavium Networks. "Cavium's OCTEON Multi-core processors with integrated hardware acceleration along with Broadcom's switches enable highly scalable solutions for enterprise, SMB and home markets."

OCTEON Multi-core MIPS64 Processors

The Cavium Networks OCTEON family of Multi-Core MIPS64 processors offers industry leading performance, scalability, low-power and advanced hardware acceleration for intelligent networking applications ranging from 100Mbps to full-duplex 10Gbps. These software-compatible processors, with one to sixteen cnMIPS cores on a single chip, integrate next-generation networking interfaces, memory controller, advanced hardware acceleration for packet processing, QoS, TCP, multi-core scaling, pattern matching, compression/decompression, storage and security with latest processor peripherals in a single chip. Additionally the OCTEON processor family provides leading throughput and general purpose programmability for Layer 2 through Layer 7 processing required for building next-generation intelligent networks.
